Description

[Technical field]

[0001] The present invention relates to an acidic liquid seasoning containing crushed plant material that exhibits excellent foam removal after mixing by stirring or shaking, and a method for producing the same. [Background technology]

[0002] Conventionally, liquid seasonings of various flavors and forms have been used in cooked foods such as salads and fried foods. Among them, seasonings containing ingredients such as grated vegetables and mashed fruits, or crushed plant materials such as purees and pastes in the seasoning liquid meet the preferences of consumers who want to enjoy the change in the taste of the food to be seasoned itself without the trouble of preparing and mixing their favorite crushed plant materials separately from the seasoning liquid.

[0003] In liquid seasonings containing crushed plant material, it is important that the flavor of the seasoning itself is evenly distributed throughout foods such as salads and fried foods with a small amount of use, and that the plant-derived flavor and texture of the crushed plant material blended in the seasoning be pleasantly felt. To date, proposals have been made to thicken the seasoning liquid itself containing crushed plant material with a thickening agent such as gum as a way to prevent the liquid seasoning from dripping from the food to be seasoned, and to adjust the size (particle size) of the crushed plant material or the blending ratio as a way to pleasantly feel the plant-derived flavor and texture of the crushed plant material blended in the liquid seasoning.

[0004] For example, JP 3-228663 A (Patent Document 1) discloses an aerated liquid seasoning containing starch and xanthan gum, and JP 2017-123817 A (Patent Document 2) discloses a liquid seasoning in which the size and amount of vegetables and sesame (crushed plant material) are adjusted.

[0005] However, when the viscosity is increased by using a thickening agent such as a gum, the liquid seasoning foams violently when stirred and mixed, and air bubbles continue to be retained in the liquid seasoning even when the liquid is left to stand after stirring and mixing, which can lead to problems such as reduced productivity, such as the liquid seasoning overflowing from tanks or containers during stirring and mixing or filling into containers in the production process.

[0006] In addition, when consumers use seasonings containing crushed plant materials on foods to be seasoned, such as salads, they generally hold the container in their hands and shake it up and down or side to side before using it so that the crushed plant materials in the seasoning liquid are evenly mixed into the seasoning liquid. However, shaking the seasoning liquid causes the seasoning liquid to foam, and air bubbles are retained in the seasoning liquid, making the seasoning liquid itself whitish and cloudy, and the color of the seasoning liquid fades, which not only prevents the vivid color of the crushed plant materials from being brought out, but also causes the air bubbles to inhibit the expression of the original flavor of the crushed plant materials in the mouth, and the bumpy texture of the air bubbles is strongly felt, making it difficult to feel the pleasant texture of the crushed plant materials.

[63] . Effect of the Invention

[0011] According to the present invention, there is provided an acidic liquid seasoning containing crushed plant material, which has excellent foam-breaking properties after mixing by stirring or shaking. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] The present invention will be described in detail below with reference to specific embodiments. However, the present invention is not limited to the following embodiments, and can be embodied in any form without departing from the spirit of the present invention.

[0013] <Liquid seasoning> According to a first aspect of the present invention, there is provided an acidic liquid seasoning containing crushed plant material, gums, cold water swelling starch, and vinegar, the acidic liquid seasoning having a viscosity and dissociated acetic acid concentration at 20°C within a specified range (hereinafter appropriately referred to as the "liquid seasoning of the present invention").

[0014] The present inventors have conducted extensive research in light of the above-mentioned problems, and have found that, in an acidic liquid seasoning containing crushed plant material, by using gums and cold water swelling starch in combination and adjusting the viscosity and dissociated acetic acid concentration of the seasoning within a predetermined range, foaming during mixing by stirring or shaking is suppressed, and the retention of air bubbles in the liquid seasoning is reduced even when left to stand after mixing, resulting in improved foam breakage. In addition, by improving the foam breakage, the retention of air bubbles in the seasoning liquid is reduced even when left to stand after mixing, so that the preferable color tone of the crushed plant material itself is maintained, and the preferable flavor, texture, and tongue feel of the original plant of the crushed plant material can be obtained without being hindered by air bubbles in the mouth. Furthermore, it has been found that the preferable flavor and texture of the original plant of the crushed plant material can be further improved by adjusting the dissociated acetic acid concentration of the liquid seasoning, and this has led to the completion of the present invention.

[0015] In the present invention, the term "liquid seasoning" refers to a seasoning having fluidity that is used to enhance the deliciousness of dishes and food ingredients. Examples of liquid seasonings include dressings that are poured over vegetables, meat, seafood, etc., as well as sauces, dipping sauces, soups, ponzu sauce, etc.

[0016] <Crushed plant material> The liquid seasoning of the present invention contains crushed vegetable matter. Examples of the "crushed vegetable matter" in the present invention include juice, puree, paste, etc. obtained by processing such as cutting or grinding vegetables or fruits. In addition, examples of the crushed vegetable matter include those which are further concentrated by processing such as heating, and dried vegetables which are dried by hot air drying, freeze drying, reduced pressure heating drying, microwave drying, etc.

[0017] Examples of vegetables include fruit vegetables such as tomatoes, green peppers, paprika, cucumbers, eggplants, and red bell peppers, root vegetables such as onions, ginger, garlic, radishes, and carrots, leafy vegetables such as cabbage, lettuce, spinach, Chinese cabbage, celery, Japanese mustard spinach, bok choy, molokheiya, kale, shiso, Chinese chives, and parsley, stem vegetables such as garlic, asparagus, and bamboo shoots, flower vegetables such as broccoli and cauliflower, and vegetables derived from other mushrooms. Among these, tomatoes, cucumbers, ginger, onions, garlic, carrots, paprika, red bell peppers, and radishes are more preferred. Vegetables are not limited to these, and one or more types can be used in any combination and ratio.

[0018] Examples of fruits include fruits derived from apples, peaches, grapes, acerola, blueberries, pears, oranges, lemons, yuzu, sudachi, limes, mandarins, grapefruits, strawberries, bananas, melons, kiwis, pineapples, blackcurrants, apricots, guavas, plums, mangoes, papayas, lychees, etc. Among these, citrus fruits such as oranges are more preferred. The fruits are not limited to these, and one or more kinds can be used in any combination and ratio. In addition, the crushed plant material obtained from these vegetables and fruits can be blended in the liquid seasoning of the present invention in any combination and ratio.

[0019] In addition, according to the present invention, since foaming and retention of bubbles are suppressed, the color tone of the crushed plant material does not become whitish and cloudy due to bubbles, and a liquid seasoning is obtained in which the vivid color tone of the crushed plant material is retained. This effect is particularly pronounced when using crushed plant material with vivid colors, such as tomatoes, paprika, cucumbers, red peppers, carrots, oranges, and other crushed plant materials with beautiful colors.

[0020] The liquid seasoning of the present invention may contain solid vegetable ingredients and non-vegetable solid ingredients or crushed products thereof in addition to the crushed vegetable ingredients. Examples of solid vegetable ingredients include onions, cucumbers, pickles, carrots, etc. Examples of solid ingredients or crushed products other than vegetable ingredients include solid ingredients or crushed products of animal ingredients such as meat, fish, and shellfish.

[0021] The liquid seasoning of the present invention preferably has a content of crushed plant material within a predetermined range. Specifically, the amount of crushed plant material is usually 0.1% by mass or more, and preferably 0.3% by mass or more, based on the mass of the liquid seasoning. If the amount of crushed plant material is less than this range, the color and flavor of the crushed plant material may be difficult to feel. On the other hand, the amount of crushed plant material is usually 30% by mass or less, and preferably 20% by mass or less, based on the mass of the liquid seasoning. If the amount of crushed plant material is more than this range, the flavor of the crushed plant material itself may be felt too strongly, and the effect of restoring or retaining the flavor of the crushed plant material, which is the effect of the present invention, may be difficult to achieve.

[0022] In addition, the crushed plant material in the liquid seasoning of the present invention may contain solids of a certain size (such as vegetable pieces and fruit pulp), but it is preferable that the crushed plant material of a certain size is contained in a certain amount or more. Specifically, the content of the crushed plant material that does not pass through a 100 mesh sieve (100 mesh on) based on the JIS test sieve standard mesh (here, if the mesh size is, for example, "No. 100", it will be appropriately expressed hereinafter. Also, passing through a mesh of a specific size may be called "mesh pass", and not passing through may be called "mesh on") relative to the total amount of crushed plant material is usually 80% by mass or more, and preferably 90% by mass or more. The desirable flavor originally possessed by the plant is lost in the process of crushing, grinding, and concentrating the plant, but if a certain amount or more of crushed plant material remains, the flavor derived from the crushed plant material is easily expressed even without the present invention, and the above-mentioned effect of the present invention is difficult to obtain. Conversely, when using plant crushed material that has a low content of such large-sized crushed material, in which the crushed plant material itself originally contains almost no solid matter, and in which the plant's original flavor and texture have been lost through processing steps such as crushing and concentration, the above-mentioned effects of the present invention will be more pronounced.

[0023] For the same reason, it is preferable that the liquid seasoning of the present invention contains a certain amount of swollen crushed plant material of a certain size. Specifically, the content of swollen crushed plant material that does not pass through a 100 mesh sieve (100 mesh on) relative to the total amount of the liquid seasoning is usually 0.2% by mass or more, preferably 0.5% by mass or more, and usually 60% by mass or less, preferably 50% by mass or less. If this content is less than the above range, the color tone and flavor of the crushed plant material itself may not be fully felt, and conversely, if it exceeds the above range, the flavor of the crushed plant material itself may become excessive, which may hinder the flavor of the entire seasoning.

[0024] In addition, when adjusting the content of the swollen crushed plant material in the liquid seasoning of the present invention, the crushed plant material alone is sufficiently swollen with water, and the crushed plant material-containing liquid is placed on a 100-mesh sieve, and the water is thoroughly drained, and the mass of the crushed plant material on the sieve is measured to adjust and determine the content. In addition, when measuring the amount of swollen crushed plant material on the 100-mesh sieve in an existing liquid seasoning, for example, the seasoning is appropriately diluted with water (about 10 to 20 times) and then placed on a 100-mesh sieve, and the components that do not pass through the sieve are obtained, and then the components other than the swollen crushed plant material (for example, swollen cold water swelling starch) are identified and removed, and the mass is measured.

[0025] Furthermore, for the same reason, it is preferable that the liquid seasoning of the present invention has a low content of large-sized swollen crushed plant material. Specifically, the content of swollen crushed plant material that passes through a 9-mesh sieve but not through a 100-mesh sieve (9-mesh pass-100-mesh on) is usually 0.2% by mass or more, preferably 0.5% by mass or more, and usually 50% by mass or less, preferably 40% by mass or less, based on the total amount of the liquid seasoning. If this content is less than the above range, the color tone and flavor of the crushed plant material itself may not be fully felt, and conversely, if it exceeds the above range, the flavor of the crushed plant material itself may become excessive, which may hinder the flavor of the entire seasoning.

[0026] In addition, when adjusting the content of the swollen crushed plant material in the liquid seasoning of the present invention, the crushed plant material alone is sufficiently swollen with water, the crushed plant material-containing liquid is placed on a 9 mesh sieve and a 100 mesh sieve, the components that pass through the former sieve and do not pass through the latter sieve are obtained, and the mass of the components that pass through the 100 mesh sieve is measured to adjust and determine the content. In addition, when measuring the amount of swollen crushed plant material that passes through 9 mesh and passes through 100 mesh in an existing liquid seasoning, for example, the seasoning is appropriately diluted with water (about 10 to 20 times) and then placed on a 9 mesh sieve and a 100 mesh sieve, the components that pass through the former sieve and do not pass through the latter sieve are obtained, and the components other than the swollen crushed plant material (for example, swollen cold water swelling starch) are identified and excluded, and the mass thereof is measured.

[0027] Depending on the composition of the liquid seasoning, it may be difficult to identify and exclude other components from the swollen crushed vegetable matter on the 100 mesh or 9 mesh pass / 100 mesh (for example, when crushed ingredients derived from foodstuffs other than plants, such as meat or dairy products, are included). However, it is considered that swollen cold water swelling starch can be relatively easily identified and excluded by visual inspection (from other components including swollen crushed vegetable matter). Therefore, in such cases, it is preferable to obtain all components of the liquid seasoning on the 100 mesh or 9 mesh pass / 100 mesh, and to have all components except for swollen cold water swelling starch (which will include swollen crushed vegetable matter) satisfy the above-mentioned specified range.

[0028] Specifically, the content of 100 mesh-on components excluding cold water swelling starch after swelling in the entire acidic liquid seasoning is usually 0.2% by mass or more, preferably 0.5% by mass or more, and usually 60% by mass or less, preferably 50% by mass or less. If this content is below the above range, the color and flavor of the crushed plant material itself may not be fully felt, and conversely, if it exceeds the above range, the flavor of the crushed plant material itself may become excessive, hindering the flavor of the entire seasoning.

[0029] Furthermore, the content of components that pass through a 9 mesh and are on through a 100 mesh, excluding cold water swelling starch after swelling, in the entire acidic liquid seasoning is usually 0.2% by mass or more, preferably 0.5% by mass or more, and usually 50% by mass or less, preferably 40% by mass or less. If this content is less than the above range, the color and flavor of the crushed plant material itself may not be fully felt, whereas if it exceeds the above range, the flavor of the crushed plant material itself may become excessive, hindering the flavor of the entire seasoning.

[0030] <Chewing gum> The liquid seasoning of the present invention contains gums as a thickening agent. Examples of "gums" in the present invention include xanthan gum, guar gum, gellan gum, locust bean gum, gum arabic, tamarind seed gum, tara gum, tragacanth gum, starch (including starch that is not a "cold water swelling starch" as defined separately below, and processed starch), and the like. Among them, xanthan gum, tamarind seed gum, and guar gum are preferred, and xanthan gum is more preferred. Only one type of gum may be used alone, or two or more types may be used in any combination and ratio.

[0031] The content of gums in the liquid seasoning of the present invention is not limited, but is usually 0.05% by mass or more, preferably 0.1% by mass or more, and usually 5% by mass or less, preferably 3% by mass or less, in terms of the mass ratio of dry gums to the entire liquid seasoning. If the content is less than the above range, it may not be possible to obtain a viscosity that does not drip from the food to be seasoned, and conversely, if it exceeds the above range, the foam may not break off well, and the flavor and texture of the crushed plant material may not be easily felt.

[0032] <Cold water swelling starch> The liquid seasoning of the present invention contains cold water swelling starch as a thickener. In the present invention, "cold water swelling starch" refers to starch that absorbs cold water at 25°C, swells, and increases in mass by more than twice. By using cold water swelling starch as a thickener in combination with the above gums and adjusting the viscosity and dissociation acetic acid constant of the liquid seasoning as described below, a liquid seasoning that has viscosity but is excellent in foam-breaking properties can be obtained. Examples of cold water swelling starch include crosslinked starch such as gelatinized starch, phosphate crosslinked starch, acetylated adipic acid crosslinked starch, acetylated phosphate crosslinked starch, acetylated oxidized starch, sodium octenyl succinate starch, acetate starch, oxidized starch, hydroxypropyl starch, hydroxypropylated phosphate crosslinked starch, phosphate monoesterified phosphate crosslinked starch, and phosphorylated starch. Only one type of cold water swelling starch may be used alone, or two or more types may be used in any combination and ratio.

[0033] More specifically, the "cold water swelling starch" to be used is one in which, when swollen in a 1% by mass aqueous solution, the component that passes through a 4 mesh screen or turns on through a 100 mesh screen is usually 80% by mass or more, and preferably 90% by mass or more. If the size is smaller than the size listed below, it is difficult to obtain the effects of preventing foam loss when stirred or shaken, and reducing the retention of air bubbles in the seasoning liquid, and the air bubbles in the seasoning liquid become an obstacle, making it difficult to express the plant-derived flavor originally possessed by the crushed plant material in the mouth, and the bumpy texture of the air bubbles becomes noticeable, making it difficult to feel the desirable texture of the plant itself originally possessed by the crushed plant material.

[0034] The content of cold water swelling starch in the liquid seasoning of the present invention is not limited, but the content of cold water swelling starch in a dry state in the entire liquid seasoning is usually 0.05% by mass or more, preferably 0.1% by mass or more, and usually 5% by mass or less, preferably 3% by mass or less. If the content is less than the above range, the effect of improving foam breaking after stirring / shaking and mixing may not be sufficiently obtained, and conversely, if it exceeds the above range, the flavor and texture of the seasoning may be impaired.

[0035] In addition, the total content of gums and cold water swelling starch in the liquid seasoning of the present invention is not limited, but is usually 0.2% by mass or more, preferably 0.3% by mass or more, and usually 10% by mass or less, preferably 7% by mass or less, in terms of the ratio of the total mass of gums and cold water swelling starch in a dry state to the entire liquid seasoning. If this ratio is below the above range, it may not be possible to impart a viscosity that prevents dripping from the food to be seasoned, and conversely, if it exceeds the above range, bubbles may break off when mixed by stirring or shaking, and the retention of bubbles in the seasoning liquid may not be reduced properly, and not only may the flavor derived from the plants originally possessed by the crushed plant material be difficult to exhibit in the mouth due to the obstruction of the bubbles, but also the lumpy texture of the bubbles may be strongly felt, resulting in an unpleasant feel on the tongue, making it difficult to obtain a favorable texture of the crushed plant material itself.

[0036] The content ratio of the gums to the cold water swelling starch in the liquid seasoning of the present invention by dry mass is not limited, but is usually at least 0.04, and preferably at least 0.05, and is usually at most 5, and preferably at most 4. If this ratio is less than the above range, or conversely, if it exceeds the above range, it may be difficult to improve the foam breaking down when mixed by stirring or shaking.

[0037] In addition, the liquid seasoning of the present invention preferably contains a certain amount of cold water swelling starch in a swollen state of a predetermined size. Specifically, the content of cold water swelling starch in a swollen state that passes through a 4 mesh sieve but not through a 100 mesh sieve (4 mesh pass-100 mesh on) relative to the total amount of the liquid seasoning is usually 0.5% by mass or more, preferably 1% by mass or more, and usually 50% by mass or less, preferably 40% by mass or less. If this content is less than the above range, it may be difficult to obtain an improvement effect on foam cutting, and conversely, if it exceeds the above range, foam cutting may be poor, and the plant-derived flavor and texture originally possessed by the crushed plant material may be difficult to feel.

[0038] The content of swollen cold water swelling starch in a liquid seasoning that passes through 4 mesh and is on through 100 mesh can be obtained, for example, by diluting the seasoning appropriately (about 10 to 20 times) with water, placing it on a 4 mesh sieve and a 100 mesh sieve, obtaining the components that pass through the former sieve and do not pass through the latter sieve, identifying and excluding other components (for example, crushed vegetable material in a swollen state), and measuring the mass of the obtained swollen cold water swelling starch.

[0039] Furthermore, when adjusting the content of swollen cold water swelling starch in the liquid seasoning of the present invention, the crushed material-containing liquid in which cold water swelling starch has been sufficiently swollen with water is placed on a 4 mesh sieve and a 100 mesh sieve, respectively, and the components that pass through the former sieve but do not pass through the latter sieve are obtained, and the mass that has been placed on the 100 mesh sieve can be measured to adjust and determine the content.

[0040] In addition, the liquid seasoning of the present invention preferably contains a certain amount of components that do not pass through a 100 mesh sieve (for example, crushed vegetable matter or cold water swelling starch). Specifically, the content of components that do not pass through a 100 mesh sieve (100 mesh on) relative to the total amount of the liquid seasoning is usually 1% by mass or more, preferably 2% by mass or more, and usually 80% by mass or less, preferably 75% by mass or less. If this content is less than the above range, it may be difficult to obtain an improvement effect on foam cutting, and conversely, if it exceeds the above range, the fluidity of the liquid seasoning itself may not be maintained. In addition, the amount of 100 on components relative to the liquid seasoning may be determined, for example, by diluting the seasoning with water appropriately (about 10 to 20 times) and then placing it on a 100 mesh sieve, obtaining the components that do not pass through the sieve, thoroughly draining the water, and then measuring the mass.

[0041] <Vinegar> The liquid seasoning of the present invention contains vinegar. The "vinegar" in the present invention includes brewed vinegar produced from grains such as rice and wheat or fruit juice as raw materials, and synthetic vinegar produced by adding seasonings such as sugar to a diluted solution of glacial acetic acid or acetic acid, or by adding brewed vinegar to it, and both can be used. Examples of brewed vinegar include rice vinegar, grain vinegar (brown rice vinegar, black vinegar, sake lees vinegar, malt vinegar, pigeon barley vinegar, soybean vinegar, etc.), fruit vinegar (apple vinegar, grape vinegar, lemon vinegar, kabosu vinegar, plum vinegar, wine vinegar, balsamic vinegar, etc.), sake vinegar produced by acetic acid fermentation using ethanol as a raw material, Chinese vinegar, sherry vinegar, etc., and examples of synthetic vinegar include glacial acetic acid or acetic acid appropriately diluted with water. These vinegars may be used alone or in combination of two or more kinds. Among them, in the present invention, it is preferable to use brewed vinegar or synthetic vinegar with a high acetic acid concentration, which has a high acetic acid content and a weak flavor derived from the raw material. The content of vinegar in the liquid seasoning of the present invention is not limited, but may be adjusted according to the acetic acid concentration, pH, and dissociated acetic acid concentration described below.

[0042] <Acetic acid and dissociated acetic acid concentration> The liquid seasoning of the present invention contains acetic acid. The acetic acid is mainly derived from the above-mentioned vinegar, but may be derived from other components. By including acetic acid, the vegetable or fruit flavor of the crushed plant material is more pleasant to taste. Furthermore, the flavor lost in the process of making the crushed plant material is restored by including acetic acid, and the flavor is perceived as being fresher. In the liquid seasoning of the present invention, acetic acid refers to a mixture of acetic acid molecules (CH3COOH) and acetate ions (CH3COO - The acetic acid content refers to the total concentration of these. In particular, acetic acid derived from vinegar, which is a food, is preferable.

[0043] The content of acetic acid in the liquid seasoning of the present invention is not particularly limited, but from the viewpoint of enhancing the taste of salads and cooked foods to be seasoned, the mass ratio to the seasoning is usually 0.1 mass% or more, and preferably 0.15 mass% or more. If the content of acetic acid is below the above range, the flavor of acetic acid may not be felt sufficiently, and the taste of the seasoning may become dull. On the other hand, from the viewpoint of taste balance, the mass ratio to the seasoning is usually 15 mass% or less, and preferably 10 mass% or less. If the content of acetic acid exceeds the above range, the sour taste and acetic acid odor tend to be more prominent than the flavor of the crushed plant material, and the flavor balance of the entire seasoning may be lost.

[0044] The liquid seasoning of the present invention is characterized in that the dissociated acetic acid concentration is within a predetermined range. In the present invention, "dissociated acetic acid concentration" means the concentration of dissociated acetic acid. Specifically, it is known that acetic acid molecules exist in an aqueous solution in dissociated and undissociated forms, and that the two are in a resonance state. Here, the dissociated acetic acid concentration is defined as [A - ], proton concentration is [H + 〕 and the concentration of undissociated acetic acid (i.e., acetic acid concentration - dissociated acetic acid concentration) is [AH], then the two coexist in equilibrium as shown in the following equation.

number

number

[0045] Specifically, the dissociated acetic acid concentration of the liquid seasoning of the present invention is usually 0.16% by mass or less, preferably 0.15% by mass or less, and more preferably 0.13% by mass or less. By setting the dissociated acetic acid concentration to the above range or less, the plant-derived flavor lost during processing steps such as crushing and concentration of the crushed plant material is restored, and the tendency to be able to feel a fresh plant-like flavor is further increased. On the other hand, the lower limit of the dissociated acetic acid concentration is not particularly limited, but it is usually 0.002% by mass or more, preferably 0.005% by mass or more, and more preferably 0.01% by mass or more, for the reason of improving the flavor of the seasoning as a whole. The dissociated acetic acid concentration of the liquid seasoning can be calculated by measuring the acetic acid concentration and pH of the liquid seasoning and using the above formula 2.

[0046] <ph> The pH of the liquid seasoning of the present invention is not particularly limited as long as it is an acidic value (less than pH 7). Usually, it may be determined from the viewpoint of the balance between flavor and taste and the above-mentioned dissociated acetic acid concentration. However, although not particularly limited, it is usually 2.2 or more, preferably 2.5 or more, and more preferably 2.8 or more, and is usually 4.8 or less, preferably 4.6 or less, and more preferably 4.4 or more.

[0047] <Viscosity> The liquid seasoning of the present invention preferably has a viscosity within a predetermined range in order to suppress foaming after stirring and mixing or shaking and the effect of retaining bubbles. Specifically, the viscosity of the liquid seasoning at 20°C is usually 500 mPa·s or more, preferably 600 mPa·s or more, more preferably 700 mPa·s or more, and is usually 10000 mPa·s or less, preferably 9500 mPa·s or less, more preferably 9000 mPa·s or less. If the viscosity of the liquid seasoning at 20°C is less than the above range, it may not be possible to prevent the crushed plant matter in the liquid seasoning or the liquid seasoning itself from dripping. On the other hand, if it exceeds the above range, there may be cases where the foam disappears when stirring and mixing or shaking, or the retention of bubbles in the seasoning liquid is not properly reduced.

[0048] In the present invention, the viscosity of a liquid seasoning at 20°C can be measured using a method known to those skilled in the art. Examples of such a measurement method include measurement using various viscometers such as a commercially available B-type viscometer (representing a single cylindrical rotational viscometer, also known as a Brookfield rotational viscometer, for example, "B-II" manufactured by Toki Sangyo Co., Ltd.). Specifically, an appropriate amount of liquid seasoning adjusted to 20°C is filled into a measurement container of a B-type viscometer, the container is set in the B-type viscometer, and the viscosity can be measured at an appropriate rotation speed using a rotor suitable for the viscosity to be measured.

[0049] <Forms of liquid seasonings and other ingredients> The liquid seasoning of the present invention may be any type of liquid seasoning, such as a non-oil type that does not contain fats or oils, a low-oil type that has a reduced amount of fats and oils (10% by mass or less), or an oil type that contains fats and oils (including emulsified and separated types), although the non-oil type, which allows the flavor of the crushed vegetable material to be more easily felt, is preferred.

Here, the mixing may be performed by stirring or shaking, and may be performed while heating as necessary. The raw materials may be mixed and stirred according to a conventionally known method, but the temperature in the above-mentioned mixing and stirring step is usually 35°C or higher, and preferably 40°C or higher. When mixing is performed while heating, the upper limit of the heating temperature is usually 100°C or lower, and preferably 90°C or lower, and more preferably 85°C or lower, in order to suppress dissolution of the cold water swelling starch.

[0069] After being made into a uniform liquid by the above process, the liquid is filled into a container as is or after being subjected to a sterilization treatment such as heat sterilization or membrane filtration sterilization, in the same manner as for general liquid seasonings. The container used for the liquid seasoning of the present invention is not particularly limited in terms of material or shape, and examples thereof include plastic containers, pouches (polyethylene pouches, aluminum pouches), PET bottles, steel cans, aluminum cans, bottle containers, and the like.

That is, the crushed plant material, gums, cold water swelling starch, vinegar, and optionally other ingredients are mixed so that the viscosity at 20°C and the dissociated acetic acid concentration are within the above-mentioned ranges. This makes it possible to improve at least one of the color, flavor, and texture of the crushed plant material in an acidic liquid seasoning containing the crushed plant material, and / or improve the foam-breaking after mixing by stirring and shaking. These methods (methods for improving the color, flavor, and texture of the plant, and methods for improving the foam-breaking after mixing by stirring and shaking) are also included in one aspect of the present invention.

[0072] <Summary> According to the present invention, an acidic liquid seasoning is provided that has excellent foam breaking after stirring and mixing or shaking, has a favorable flavor and texture that the crushed plant material originally had, and maintains a vivid color. The acidic seasoning containing the crushed plant material of the present invention has excellent foam breaking when stirred and mixed, so that the seasoning liquid is less likely to flow out of the tank or container due to foaming after stirring and high bubble retention, which is seen in conventional acidic liquid seasonings containing crushed plant material, and the decrease in productivity is improved. In addition, by suppressing foaming caused by shaking the liquid seasoning before pouring it over the food material and the subsequent bubble retention, the color tone that the crushed plant material originally has does not become cloudy white due to the bubbles, and the color development does not decrease. Furthermore, by improving the retention of bubbles in the seasoning liquid, the original flavor of the crushed plant material can be strongly felt without being hindered by the bubbles in the mouth, and the original favorable texture of the crushed plant material can be felt without being hindered by the bumpy texture of the bubbles. EXAMPLES

[0073] The present invention will be described in more detail below with reference to examples. However, these examples are merely illustrative and are not intended to limit the present invention in any way.

[0074] [Example 1] Examination of thickener content and viscosity (1) Preparation of test samples Tomato paste (crushed vegetable matter), salt, sugar, brewed vinegar (acidity 15%), and water were mixed in the amounts shown in Table 1 below, and xanthan gum (gums) and cold water swelling starch were mixed in different combinations and ratios, thoroughly stirred and mixed at 60°C until homogeneous, then sterilized at 90°C for 5 minutes and bottled to prepare acidic liquid seasoning test samples No. 1 to 8. When the entire amount of the tomato paste was placed on a 100 mesh sieve, 90% by mass or more was passed through the 100 mesh sieve.

[0075] (2) Test item evaluation procedure [Viscosity measurement] The viscosity of the test sample prepared in (1) below was measured by the following procedure: A "B-II" manufactured by Toki Sangyo Co., Ltd. was used as a Brookfield viscometer, and an appropriate amount of the test sample adjusted to 20°C was filled into the measurement container of the Brookfield viscometer, the container was set in the Brookfield viscometer, and the viscosity was measured at an appropriate rotation speed using a rotor suitable for the viscosity to be measured.

[0076] [Measurement of pH and calculation of dissociated acetic acid concentration] The pH of the test seasonings prepared in (1) below was measured using a pH meter. The acetic acid concentration of the seasonings was calculated from the content and acidity of the vinegar used. The dissociated acetic acid concentration was calculated from the pH and acetic acid concentration of the seasonings obtained using the following formula.

number

[0077] [Measurement of content of all components on 100 mesh screen] For the test samples prepared in (1) below, the content of all components on a 100 mesh screen relative to the test seasoning was measured by the following procedure: The test seasoning was diluted 10 times with water and then placed on a 100 mesh sieve, and the components that did not pass through the 100 mesh sieve were obtained and their mass was measured to determine the content relative to the seasoning.

[0078] [Measurement of cold water swelling starch content after swelling] The content of cold water swelling starch after swelling was measured for the test samples prepared in (1) below by the following procedure. First, the test seasoning was diluted 10 times with water and placed on 100 mesh and 4 mesh sieves, and the components that did not pass through the 100 mesh sieve but passed through the 4 mesh sieve were obtained. Here, judging from the composition of the test sample, the components that did not pass through the 100 mesh sieve were considered to be only the cold water swelling starch after swelling and the crushed vegetable matter, so these were visually identified, and only the cold water swelling starch components after swelling were separated and obtained. In addition, the same amount of dry cold water swelling starch used in the test seasoning was separately prepared, and after absorbing a sufficient amount of cold water (25°C) to swell, the components that did not pass through the 100 mesh sieve were obtained by the same procedure. The masses of both components obtained were measured and found to be almost the same. Therefore, for simplicity, the value obtained by the latter procedure was used as the mass of the cold water swelling starch after swelling in the following, and the content relative to the seasoning was calculated.

[0079] [Measurement of plant crushed material content after swelling] The content of crushed vegetable matter after swelling was measured for the test sample prepared in (1) below by the following procedure. First, the test seasoning was diluted 10 times with water and placed on 100-mesh and 9-mesh sieves, and the components that did not pass through the 100-mesh sieve but passed through the 9-mesh sieve were obtained. Here, judging from the composition of the test sample, the only components that did not pass through the 100-mesh sieve were thought to be cold water swelling starch and crushed vegetable matter after swelling. Therefore, these were visually identified, and only the components of the crushed vegetable matter after swelling were separated and obtained. In addition, the same amount of crushed vegetable matter as that used in the test seasoning was separately prepared, and after it was allowed to absorb a sufficient amount of water to swell, the components that did not pass through the 100-mesh sieve were obtained by the same procedure. When the masses of both components were measured, they were found to be almost the same. Therefore, for simplicity, the value obtained by the latter procedure was used as the mass of the crushed plant material after swelling, and the content relative to the seasoning was calculated.

[0080] [Sensory test] The test products prepared in (1) below were subjected to sensory tests for "froth-cutting ability after shaking" and "color tone after shaking". The sensory tests were performed by five experienced panelists, and the evaluation criteria for each test item were as follows. Each evaluation was performed on a three-level scale: "good", "average", and "bad". When the majority (three out of five) of the panelists rated "good" and no one rated "bad", the effect of the present invention was deemed to be recognized. The panelists who performed the sensory tests were experienced panelists who were familiar with commercially available liquid seasonings that are normally distributed in the general public, and who had a thorough understanding of the general levels (evaluation of "average") of froth-cutting ability, color tone, flavor, and texture.

[0081] (Easy foam removal after shaking) The bottle containing the test product was shaken up and down over a width of 30 cm at a speed of two strokes per second for 15 seconds, and then left to stand for 3 minutes. After that, the appearance of the liquid seasoning in the container was visually inspected and evaluated using the following scale. : Good (virtually no foaming is observed at the top of the liquid, and almost no foam is observed in the liquid.) ○: Normal (Foam over 1 cm is seen at the top of the liquid, and bubbles are seen in most of the liquid.) ×: Poor (Intense bubbling over 2 cm is observed at the top of the liquid, and bubbles are observed throughout almost the entire liquid portion)

[0082] (Color after shaking) The bottle containing the test product was shaken up and down over a width of 30 cm at a speed of two strokes per second for 15 seconds, and then left to stand for 3 minutes. After that, the appearance of the liquid seasoning in the container was visually inspected and evaluated using the following scale. ◎: Good (There is virtually no change in color before and after shaking, and no turbidity occurs after shaking.) ○: Normal (there is a slight color change before and after shaking, but no turbidity occurs after shaking) ×: Poor (there is a clear change in color before and after shaking, and the mixture becomes cloudy after shaking)

[0083] (3) Evaluation results of test items The compositions of test samples No. 1 to 8, the results of viscosity measurements, the contents of cold water swelling starch and crushed vegetable material after swelling, and the results of sensory tests are shown in Table 1. In addition, in the following tables and in other tables, "content" refers to the content in the entire seasoning unless otherwise specified. [Table 1]

[0084] As shown in Table 1 above, in liquid seasonings that use tomato paste as the crushed vegetable matter and are blended with salt, sugar, brewed vinegar (acidity 15%), and cold water swelling starch, when xanthan gum (gums) and cold water swelling starch are used as thickeners and the dissociated acetic acid concentration is adjusted to 0.15% by mass or less, in the liquid seasonings of test samples No. 3 to 6 and 8, which have a viscosity in the range of 500 to 10,000 mPa·s, foaming after mixing is suppressed, foam retention in the liquid is reduced, and foam tends to break down easily. In addition, there was no whitish turbidity due to air bubbles after shaking, and there was almost no change in color before and after shaking, and the vivid color derived from the crushed vegetable matter was maintained. On the other hand, test sample No. 1, which had a viscosity of less than 500 mPa s, test sample No. 7, which had a viscosity of more than 10,000 mPa s, and test sample No. 2, which did not use cold water swelling starch as a thickener, were poor in terms of foam cutting and were also unsatisfactory in terms of other evaluation items.

[0085] [Example 2] Examination of the content of crushed plant material (1) Preparation of test samples According to the blending amounts shown in Table 2 below, salt, sugar, brewed vinegar (acidity 15%), xanthan gum (gums), cold water swelling starch, and water were blended together with the above tomato paste A (crushed vegetable material) in different blending amounts, thoroughly stirred and mixed at 60°C until homogeneous, then sterilized at 90°C for 5 minutes and bottled to prepare acidic liquid seasoning test samples Nos. 9 to 11. When the entire amount of the above tomato paste A was placed on a 100 mesh sieve, 90% by mass or more was passed through the 100 mesh sieve.

[0086] (2) Test item evaluation procedure For test samples No. 9 to 11 prepared in (1) below, the viscosity was measured, the contents of cold water swelling starch and crushed plant material after swelling were measured, and a sensory test was performed in the same manner as in Example 1 (2).

[0087] (3) Evaluation results of test items The compositions of test samples Nos. 9 to 11, the results of viscosity measurements, the contents of cold water swelling starch and crushed vegetable material after swelling, and the results of sensory evaluation are shown in Table 2 below. [Table 2]

[0088] As shown in Table 2 above, in liquid seasonings containing tomato paste as the crushed vegetable matter, salt, sugar, brewed vinegar (acidity 15%), and cold water swelling starch, when xanthan gum (gums) and cold water swelling starch were used as thickeners, and the dissociated acetic acid concentration was adjusted to 0.15% by mass or less and the viscosity to 500-10,000 mPa·s, the liquid seasonings No. 9-11, in which the tomato paste content was in the range of 0.3-20% by mass (100 mesh on and 9 mesh pass·100 mesh on after swelling were both in the range of 0.6-40% by mass), showed a tendency for foaming to be suppressed after stirring and mixing, as well as a decrease in foam retention in the liquid and a tendency for foam to break down easily. In addition, the color tone after shaking did not become whitish due to air bubbles, and there was almost no change in color tone before and after shaking, and the vivid color derived from the crushed vegetable matter was maintained.

[0089] [Example 3] Study on dissociated acetic acid concentration (1) Preparation of test samples According to the amounts shown in Table 3 below, the above tomato paste A (crushed vegetable matter), salt, sugar, xanthan gum (gums), cold water swelling starch, and water were mixed, along with varying amounts of brewed vinegar (acidity 15%) and sodium citrate, if necessary, for pH adjustment. The mixture was thoroughly stirred and mixed at 60°C until homogeneous, then sterilized at 90°C for 5 minutes and bottled to prepare acidic liquid seasoning test samples No. 12 to 17.

[0090] (2) Test item evaluation procedure For test samples No. 12 to 17 prepared in (1) below, the viscosity was measured, the contents of cold water swelling starch and crushed plant material after swelling were measured, and a sensory test was performed in the same manner as in Example 1 (2).

[0091] (3) Evaluation results of test items The compositions of test samples Nos. 12 to 17, the results of viscosity measurements, the contents of cold water swelling starch and crushed vegetable material after swelling, and the results of sensory tests are shown in Table 3 below. [Table 3]

[0092] As shown in Table 3 above, in liquid seasonings containing tomato paste as crushed vegetable matter, salt, sugar, brewed vinegar (acidity 15%), and cold water swelling starch, when xanthan gum (gums) and cold water swelling starch were used as thickeners and the viscosity was adjusted to 500-10,000 mPa·s, the liquid seasonings No. 12, 13, 16, and 17, which had a dissociated acetic acid concentration in the range of 0.15 mass% or less, showed a tendency to suppress foaming after stirring and mixing, to reduce foam retention in the liquid, and to improve foam removal. In addition, the color tone after shaking was not whitish due to air bubbles, and there was almost no change in color tone before and after shaking, and the vivid color derived from the crushed vegetable matter was maintained. On the other hand, the liquid seasonings No. 14 and 15, which had a dissociated acetic acid concentration of more than 0.15 mass%, showed poor foam removal and were insufficient in terms of other evaluation items.

[0093] [Example 4] (1) Preparation of test samples According to the blend amounts shown in Tables 4-1 and 4-2 below, test samples No. 18 to 27 of acidic liquid seasonings were prepared by varying the types and amounts of crushed plant matter, gums, and vinegar, and blending other ingredients in addition to salt, sugar, and water.

[0094] (2) Test item evaluation procedure For test samples No. 18 to 27 prepared in (1) below, the viscosity was measured, the contents of cold water swelling starch and crushed plant material after swelling were measured, and a sensory test was performed in the same manner as in Example 1 (2).

[0095] (3) Evaluation results of test items The compositions, viscosity measurement results, contents of cold water swelling starch and crushed vegetable material after swelling, and sensory test results of test samples No. 18 to 27 are shown in Tables 4-1 to 4-4 below. [Table 4-1] [Table 4-2] [Table 4-3] [Table 4-4]

[0096] As shown in Tables 4-1 to 4-4 above, in all of the test samples No. 18 to 27, foaming after stirring and mixing was suppressed, foam retention in the liquid was reduced, and the foam tended to break down easily. In addition, the color tone after shaking and mixing was not whitish and cloudy due to bubbles, and there was almost no change in color tone before and after shaking and mixing, so the vivid color derived from the crushed plant material was maintained. In addition, the test samples using tomato puree, cucumber, red pepper, carrot, and orange, which are crushed plant materials with vivid colors, maintained the vivid color derived from the crushed plant material in particular. [Industrial Applicability]

[0097] The present invention can be widely used in the food industry for acidic liquid seasonings containing crushed plant material, and is therefore of great industrial utility.< / ph>
