Description

Technical Field

[0001] The present invention relates to an oil-in-water emulsified composition and a beverage comprising the emulsified composition. Background Art

[0002] Milk proteins such as casein have both high emulsification and solubility, and therefore are widely used as raw materials for creamers used in coffee and black tea. In addition, it is known that the dispersion stability of oil droplets in beverages is improved by combining highly hydrophilic sucrose fatty acid esters with milk proteins. In this case, it is known that excellent effects can be achieved by adding sucrose fatty acid esters in an amount less than that of milk proteins (for example, Patent Documents 1 to 3). In addition, foods that combine highly hydrophilic sucrose fatty acid esters with milk proteins have also been studied (Patent Documents 4 and 5). If people who are allergic to milk consume the above-mentioned beverages and foods using milk proteins, it will become a serious problem, and therefore, beverages and foods using plant proteins are sought.

[0003] In place of milk protein, plant-derived proteins such as soy protein and pea protein may be used.

[0004] For example, Patent Documents 6, 7, and 8 propose oil-in-water emulsion compositions containing pea protein and an emulsifier such as sucrose fatty acid ester.

[0015] Problem that the invention aims to solve

[0016] However, conventional oil-in-water emulsion compositions containing plant-derived proteins such as soybean protein and pea protein and sucrose fatty acid ester all have the problem of agglomeration and oil-fat separation due to shaking during circulation, resulting in a decrease in quality.

[0017] The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide an oil-in-water emulsion composition and a beverage using the same, which stabilizes the emulsified state and has better circulation stability even when pea protein and / or broad bean protein and sucrose fatty acid ester are used.

[0018] Solutions for solving problems

[0019] The present inventors have focused on the technology of the existing oil-in-water emulsion composition, which is to mix a large amount of plant-derived proteins such as soybean protein and pea protein, and a small amount of sucrose fatty acid ester with high hydrophilicity. Soy protein contains high molecular weight proteins such as β-conglycinin (molecular weight of about 150,000) and glycinin (molecular weight of about 43,000), and pea protein contains a large amount of convicilin (molecular weight of about 75,000) and vicilin (molecular weight of about 45,000). Compared with milk protein, which contains a large amount of lower molecular weight proteins such as casein (molecular weight of 25,000) and β-lactoglobulin (molecular weight of about 18,300), these proteins are not easily dispersed in water and have weak emulsification power. Therefore, it is believed that the existing oil-in-water emulsion composition is prone to aggregation and oil separation.

[0020] The present inventors have found that the above-mentioned problems can be solved by adding pea protein and / or broad bean protein so that the sucrose fatty acid ester has a specific small amount of sucrose fatty acid ester in the monoester composition and by mixing pea protein and / or broad bean protein with the sucrose fatty acid ester in a specific ratio, thereby obtaining an emulsified composition having a more highly stabilized emulsified state and excellent circulation stability.

[0021] The present invention has been accomplished based on such findings, and the following is the gist of the present invention.

[0023] [2] The oil-in-water emulsion composition according to [1], wherein the content of milk protein is 0.5% by mass or less.

[0024] [3] The oil-in-water emulsion composition according to [1] or [2], which does not contain milk protein.

[0027] [6] The oil-in-water emulsion composition according to any one of [1] to [5], wherein the content of the oil and fat is 25 to 50% by mass.

[0028] [7] The oil-in-water emulsion composition according to any one of [1] to [6], further comprising a glycerol fatty acid ester.

[0029] [8] A beverage comprising the oil-in-water emulsion composition according to any one of [1] to [7].

[0030] [9] A beverage comprising 0.2 to 42% by mass of the oil-in-water emulsion composition according to any one of [1] to [7].

[0031]

[10] A beverage comprising: water, oil, pea protein and / or broad bean protein, and sucrose fatty acid esters, wherein the ratio of sucrose fatty acid monoesters contained in the sucrose fatty acid esters is 3 to 45% by mass relative to all sucrose fatty acid esters, and the amount of the sucrose fatty acid esters is 1 to 30 parts by mass relative to 1 part by mass of the total amount of the pea protein and the broad bean protein.

[0032] Effects of the Invention

[0033] According to the present invention, it is possible to provide an oil-in-water emulsion composition having a highly stabilized emulsified state and excellent circulation stability, and a beverage containing the same.

[0034] Furthermore, according to the embodiment [6], an emulsified composition having a higher oil concentration can be obtained, thereby improving the transport efficiency per unit oil and reducing the storage space of the oil-in-water emulsified composition.

[0039] <Oil and fat>

[0040] The higher the oil content of the water-in-oil emulsion composition of the present embodiment, the more it can improve the transport efficiency of the unit oil and reduce the storage space of the water-in-oil emulsion composition. From this viewpoint, the oil content of the water-in-oil emulsion composition is preferably 25% by mass or more, more preferably 31% by mass or more, and further preferably 33% by mass or more. On the other hand, from the viewpoint of fully obtaining the stability improvement effect during circulation brought about by the pea protein and / or broad bean protein and sucrose fatty acid ester used in the present invention, the oil content of the water-in-oil emulsion composition is preferably 50% by mass or less, more preferably 46% by mass or less, further preferably 41% by mass or less, and most preferably 38% by mass or less.

[0041] Therefore, the oil-in-water emulsion composition of the present embodiment may contain lipid-containing components such as fats and oils and milk components described below so that the fat content of the resulting beverage falls within the above-described preferred range.

[0042] The oil content of the oil-in-water emulsion composition can be calculated from the oil ratio of each component contained in the oil-in-water emulsion composition and the content rate of the component.

[0043] As the fat, known fats and oils can be used. For example, it can be animal fats and oils such as fish oil, tallow, lard, milk fat (butter, anhydrous butter), horse oil, snake oil, egg oil, egg yolk oil, tortoise oil, mink oil, etc. When making food for people with milk allergies, it is preferred to use vegetable fats and oils, and soybean oil, corn oil, cottonseed oil, rapeseed oil, sesame oil, perilla seed oil, rice bran oil, sunflower seed oil, peanut oil, olive oil, palm oil, palm kernel oil, rice germ oil, wheat germ oil, brown rice germ oil, coix seed oil, garlic oil, macadamia nut oil, avocado oil, Vegetable oils and fats such as evening primrose oil, safflower oil, camellia oil, coconut oil, castor oil, linseed oil, and cocoa butter: and those obtained by hydrogenation or transesterification thereof, such as MCT (medium-chain fatty acid oil) obtained by oil processing such as purification, deodorization, fractionation, hardening, and transesterification of the liquid or solid forms of these vegetable oils and fats, hardened oils such as hardened coconut oil and hardened palm kernel oil, processed oils, liquid oils obtained by further fractionation of these oils, solid fats, etc.; medium-chain fatty acid triglycerides, etc.

[0044] Among these, corn oil, cottonseed oil, rapeseed oil, perilla seed oil, rice bran oil, sunflower seed oil, olive oil, palm oil, palm kernel oil, rice germ oil, brown rice germ oil, coix seed oil, garlic oil, avocado oil, evening primrose oil, safflower oil, camellia oil, coconut oil, castor oil, linseed oil, cocoa butter, and hydrogenated or transesterified products thereof are preferred from the viewpoint of not containing allergenic substances. Furthermore, palm kernel oil, coconut oil, and hydrogenated or transesterified products thereof are preferred from the viewpoint of flavor or oxidative degradation when prepared as an oil-in-water emulsion composition, and hardened palm kernel oil and hardened coconut oil obtained by hydrogenating palm kernel oil and coconut oil are most preferred.

[0045] The oil-in-water emulsion composition of the present embodiment may contain only one of these fats and oils, or may contain two or more of them.

[0046] In the oil-in-water emulsion composition of the present embodiment, such fat is used in a manner such that the fat content in the oil-in-water emulsion composition and the beverage is within the above-mentioned suitable range, calculated in total with the lipids contained in other lipid-containing components, such as the milk / soy milk components described later.

[0047] Among them, when vegetable oils and fats are used, from the perspective of having a light taste when consumed as a beverage and easily becoming a preferred flavor, it is preferably contained in 50% by mass or more of the oil and fat in the oil-in-water emulsion composition, more preferably 70% by mass or more, and most preferably 90% by mass or more.

[0051] <Sucrose fatty acid ester>

[0052] The sucrose fatty acid ester used in the present invention has a ratio of sucrose fatty acid monoester to the total sucrose fatty acid ester of 3 to 45% by mass. Pea protein and broad bean protein have a high molecular weight and low hydrophilicity compared to ordinary milk protein, and therefore, by using a sucrose fatty acid ester having a ratio of sucrose fatty acid monoester in the above range, these proteins can be arranged at the oil-water interface.

[0053] For the ratio of the sucrose fatty acid monoester contained in the sucrose fatty acid ester, from the viewpoint of the circulation stability of the oil-in-water emulsion composition, relative to all sucrose fatty acid esters, preferably 9% by mass or more, more preferably 15% by mass or more, further preferably 20% by mass or more, and particularly preferably 25% by mass or more. On the other hand, preferably 45% by mass or less, more preferably 42% by mass or less. That is, preferably 9 to 45% by mass, more preferably 15 to 45% by mass, further preferably 20 to 42% by mass, and particularly preferably 25 to 42% by mass. The ratio of sucrose fatty acid monoester can be obtained based on the area ratio of the chromatogram when tetrahydrofuran (THF) or the like is used as an eluent and GPC analysis is performed. In addition, when a plurality of sucrose fatty acid esters whose ratios of sucrose fatty acid monoesters are known are used in combination, the ratio of the sucrose fatty acid monoester in the oil-in-water emulsion composition can be calculated from their blending ratios.

[0054] The structural unit derived from the fatty acid in the sucrose fatty acid ester uses a known fatty acid such as palmitic acid, stearic acid, and oleic acid. Specific examples of sucrose fatty acid esters include sucrose palmitate, sucrose stearate, sucrose myristate, and sucrose oleate. Among these, sucrose palmitate and sucrose stearate are preferred from the viewpoint of the flavor and stability of the oil-in-water emulsion composition, and sucrose stearate is most preferred.

[0055] Sucrose fatty acid ester is a known food emulsifier per se, and commercially available sucrose fatty acid ester can be used. For example, "Ryoto syuga ester S-1670", "Ryoto syuga ester S-1570", "Ryoto syugaester P-1670", "Ryoto syuga ester M-1695", "Ryoto syuga ester S-1170", "Ryoto syuga ester S-970", "Ryoto syuga ester S-770", "Ryoto syuga ester S-570", "Ryoto syuga ester S-370", "Ryoto syuga ester S-270", "Ryoto syuga ester L-595" (above, manufactured by Mitsubishi Chemical Corporation, trade names); "DK ester SS", "DK ester F-160", "DK ester F-140", "DK ester F-110" (above, manufactured by Dai-ichi Kogyo Seiyaku Co., Ltd., trade names); and the like can be cited. In the oil-in-water emulsion composition of the present embodiment, the sucrose fatty acid ester may be contained alone or in combination of two or more types, as long as the sucrose fatty acid monoester ratio is in the range of 3 to 45% by mass.

[0056] As the sucrose fatty acid ester, a sucrose fatty acid ester having a high selectivity for monoester produced by irradiating microwaves as described in Japanese Patent No. 5945756 can be used.

[0057] The content of sucrose fatty acid esters having a sucrose fatty acid monoester ratio of 3 to 45% by mass in the oil-in-water emulsion composition of the present embodiment is preferably 0.05% by mass or more, further preferably 0.1% by mass or more, more preferably 0.4% by mass or more, further preferably 0.7% by mass or more, and particularly preferably 1% by mass or more. On the other hand, the content of sucrose fatty acid esters having a sucrose fatty acid monoester ratio of 3 to 45% by mass in the oil-in-water emulsion composition of the present embodiment is preferably 5% by mass or less, more preferably 4% by mass or less, and further preferably 3% by mass or less. By making the sucrose fatty acid ester content within the above-mentioned preferred range, an appropriate stability improvement effect during circulation based on the sucrose fatty acid ester can be obtained, and there is a tendency to maintain the appropriate flavor of the oil-in-water emulsion composition.

[0105] It should be noted that the content of fat and oil and pea protein and / or broad bean protein in the beverage can be obtained by calculation from the protein ratio in the protein-containing components in the beverage and the content rate of the components.

[0106] In addition, the beverage of this embodiment may contain sucrose fatty acid esters other than those derived from the oil-in-water emulsion composition of one embodiment of the present invention. The sucrose fatty acid esters other than those derived from the above-mentioned oil-in-water emulsion composition can be the same as those described above. Among these, sucrose palmitate and sucrose stearate are preferred from the viewpoint of the flavor and stability of the beverage, and sucrose palmitate is most preferred.

When other products are used as food emulsifiers, the HLB can also refer to the catalog value. When the catalog value is unclear, or when the food emulsifier is synthesized and used by itself, the HLB can be determined according to a known method. The calculation methods of HLB include the Atlas method, the Griffin method, the Davis method, the Kawakami method, etc., and there is also a method of determining it by the retention time in high performance liquid chromatography.

[0112] Coffee or coffee beverages usually contain coffee ingredients. As coffee ingredients, coffee ingredients derived from coffee extract are usually used. As coffee beans for making coffee extract, any coffee beans can be used, for example, Arabica species from Brazil, Colombia, Peru, Kilimanjaro, etc., Robusta species from Indonesia, Uganda, etc., which can be used alone or in combination. The roasting conditions, grinding conditions, extraction conditions, etc. of coffee beans can also be arbitrarily selected.

[0113] There is no particular restriction on the amount of coffee extract to be added, and it is generally used in a manner that is about 0.3 to 1.5% by mass of the beverage of this embodiment, based on the solid content of the coffee extract in the beverage.

[0115] <Method for producing oil-in-water emulsion composition>

[0116] The oil-in-water emulsion composition according to one embodiment of the present invention is produced, for example, as follows.

[0117] First, a mixing step is performed in which a fat-containing component such as vegetable fat, pea protein and / or broad bean protein, sucrose fatty acid ester, and the like, and any compounding agent components are mixed together with water or the like as required to prepare a mixed solution.

[0118] Next, an emulsification step is performed in which the obtained mixed solution is stirred and emulsified. As the emulsification method, a homogenization emulsification method commonly used in food can be used. For example, a method using a homogenizer, a method using a colloid mill, and a method using a homogenizer mixer can be mentioned. The homogenization emulsification treatment is usually carried out at 40 to 80°C.

[0119] The emulsification step may be performed only once, or may be performed two or more times (multiple times).

[0120] The multiple emulsification step refers to the operation of introducing the treated material into an emulsifier multiple times, performing emulsification treatment under predetermined conditions, and then taking out the emulsified material. The emulsifiers used in the multiple emulsification treatments may be the same or different.

[0121] In the production of the oil-in-water emulsion composition according to one embodiment of the present invention, it is preferred to perform the emulsification step twice or more from the viewpoint of emulsion stability.

[0122] In the case of mass production in a factory, the emulsification treatment is preferably a high-pressure emulsification treatment because of its higher production efficiency and greater processing capacity per unit time.

[0123] High-pressure emulsification treatment, for example, is the following treatment: by using a pump to deliver liquid to the gap, flow path, nozzle, etc. of a narrow homogenizing valve, the pressure of the treated object, which is in a high-pressure state, is reduced at one time, and the flow rate is accelerated under the energy of the pressure difference, so that the treated object collides with the valve, ring, or each other at high speed, thereby generating turbulence, cavitation, and shear force, and using their energy, the treated object is subdivided and emulsified.

[0124] Specifically, the high-pressure emulsification is performed under a treatment pressure of preferably 10 MPa or more, more preferably 15 MPa or more, at the time of high-pressure emulsification in a one-stage process, and under a treatment pressure of preferably 10 MPa or more, more preferably 15 MPa or more, at least in one stage of high-pressure emulsification in a two-stage or other multi-stage process. The higher the treatment pressure of the emulsification treatment, the more sufficiently fine particles of the oil and fat can be formed and uniformly emulsified and dispersed, which is preferred.

[0125] In terms of emulsification stability, there is no particular upper limit on the processing pressure, but it is usually 200 MPa or less in terms of the pressure resistance of the emulsifier used and industrial practicality. Ideally, the processing pressure is preferably 100 MPa or less, more preferably 80 MPa or less, further preferably 50 MPa or less, and most preferably 45 MPa or less.

[0126] Examples of commercially available emulsifiers used in the high-pressure emulsification treatment include valve-type emulsifiers such as GAURIN 125T and 132T manufactured by SPX Corporation and HV-5H and HV-5E manufactured by IZUMI FOOD MACHINERY Co., Ltd., nozzle-type emulsifiers such as NanoVater manufactured by Yoshida Machine Co., Ltd. and Star burst 100 manufactured by Suginoo Machine Limited, and chamber-type emulsifiers such as Microfluidizer manufactured by Powrex Corp.

[0127] The processing capacity per unit time in the high-pressure emulsification treatment is usually 0.1 ton / hour or more, preferably 1 ton / hour or more, more preferably 5 tons / hour or more, and most preferably 10 tons / hour or more. By achieving such a processing capacity, the high-pressure emulsification treatment can be carried out without reducing the production efficiency. The upper limit of the processing capacity per unit time in the high-pressure emulsification treatment is not particularly limited, but is usually 500 tons / hour or less.

[0128] The emulsification treatment time for each treatment varies depending on the treatment amount and treatment pressure, and is generally 0.005 hours or more, preferably 0.01 hours or more, and most preferably 0.1 hours or more, and is generally 20 hours or less, preferably 10 hours or less, more preferably 5 hours or less, particularly preferably 2 hours or less, and most preferably 1 hour or less, in order to obtain good emulsification stability without impairing productivity, particularly in the case of mass production in a factory.

[0129] The temperature during the high-pressure emulsification treatment is usually 30°C or more, preferably 40°C or more, more preferably 50°C or more, and usually 100°C or less, preferably 90°C or less, more preferably 80°C or less. When the treatment temperature is above the lower limit, it is preferred in terms of emulsification efficiency. In addition, in terms of the operability of the emulsion, the treatment temperature is preferably below the upper limit. The treatment temperature may be different or the same each time.

[0130] In addition, the pH of the treated material during the emulsification treatment is usually 5.0 or more, preferably more than 5.0, more preferably 5.2 or more, further preferably 5.5 or more, and particularly preferably 6.0 or more, and is usually 9.0 or less, preferably 8.0 or less, from the perspective of fully dispersing the emulsifier used in water and emulsifying the oil efficiently. The pH of the treated material can be adjusted by adding a pH adjuster such as baking soda, phosphate, or other additives to the treated material.

[0131] In the method for producing the oil-in-water emulsion composition, for example, a pre-emulsification step may be performed before the emulsification step of the high-pressure emulsification treatment described above. This step may be performed using a paddle mixer, a homomixer, an ultrasonic homogenizer, a colloid mill, a kneader, an in-line mixer, a static mixer, a scraped-surface heat exchanger (onlator), or the like.

[0132] In addition, the pre-emulsification can be carried out under low pressure or normal pressure. The temperature is usually 30°C or higher, preferably 40°C or higher, more preferably 50°C or higher, and usually 100°C or lower, preferably 90°C or lower, more preferably 80°C or lower. The treatment time is usually 0.005 hours or more, preferably 0.01 hours or more, and on the other hand, it is usually 20 hours or less, preferably 10 hours or less. That is, the treatment time is usually 0.005 to 20 hours, preferably 0.01 to 10 hours.

[0133] After the emulsification process, a sterilization process such as UHT sterilization and retort sterilization is performed. Usually, retort sterilization is performed at 110 to 140°C, for example, 121°C, for 10 to 40 minutes. On the other hand, UHT sterilization used in PET bottle beverages, etc. is an ultra-high temperature sterilization at a higher temperature, for example, a sterilization temperature of 120 to 150°C, and a sterilization value (Fo) at 121°C equivalent to 10 to 50. UHT sterilization can be performed by a known method such as a steam injection method in which water vapor is directly blown into the beverage, a direct heating method such as a steam injection method in which the beverage is sprayed into water vapor and heated, and an indirect heating method using a surface heat exchanger such as a plate or tube. For example, a plate sterilizer can be used.

[0134] The obtained emulsified composition can be filled into cans, bottles, plastic bottles, paper bags, plastic containers, etc. These filled materials can be distributed.

[0135] <Drink production method>

[0136] The method for producing a beverage according to one embodiment of the present invention may be a known method. For example, the method includes a step of mixing the emulsified composition obtained above with other beverage materials. The beverage according to one embodiment of the present invention may be obtained from the mixture obtained through the same steps as the emulsification step and sterilization step in the emulsified composition.

[0137] It should be noted that the manufactured beverage is suitable for container-packed beverages, for example, canned beverages, plastic bottle beverages, paper bag beverages, bottled beverages, plastic container beverages, etc.
