Description

[Technical Field]

[0001] The present invention relates to an instant acidic beverage composition for preparing an acidic milk beverage by dissolving it in animal milk or vegetable milk, and a method for producing the same. [Background technology]

[0002] Instant beverage compositions, which contain soluble solids from beverages as their main ingredients, are generally in the form of powders that can be dissolved in a liquid such as water to prepare instant beverages. These compositions have recently become extremely popular due to their ease of preparation. In particular, by dissolving the instant beverage composition in milk, a beverage having the richness and flavor of milk can be easily prepared.

[0003] On the other hand, unlike water, milk contains various components including proteins. Therefore, depending on the composition of the instant beverage composition, it may interact with the components contained in the milk, resulting in a loss of beverage quality. In particular, when preparing an acidic beverage such as an acidic milk beverage, the instant acidic beverage composition for preparing the acidic beverage contains a large amount of acidic components such as organic acids, and dissolving this in milk causes a rapid drop in pH. As a result, the proteins in the milk aggregate and separate into curds and whey, making it impossible to prepare an acidic beverage.

[0004] Several methods have been reported for suppressing the formation of curd when an instant acidic beverage composition is dissolved in milk. For example, Patent Document 1 discloses a method of coating a powder composition with a solution of an organic acid and a buffer dissolved in water, followed by drying. The presence of the organic acid together with the buffer on the surface of the powder composition makes it possible to prepare a beverage that has a moderate sourness but suppresses the formation of curd when dissolved in milk. Furthermore, Patent Document 2 discloses a powder composition for instant acidic beverages obtained by coating a powder composition containing a finely powdered acidulant with a binder liquid containing an emulsifier, followed by drying. Because this powder composition contains the acidulant in the form of a fine powder, curd is less likely to form when dissolved in milk. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 61-1346 [Patent Document 2] Japanese Patent Application Laid-Open No. 2016-21878 Summary of the Invention [Problem to be solved by the invention]

[0006] The powder composition for an instant acidic beverage obtained by the method described in Patent Document 1 has the problem that it tends to caking during storage due to the organic acid on the surface of the powder, resulting in reduced solubility. On the other hand, the powder composition for an instant acidic beverage described in Patent Document 2 is less likely to caking during storage because the acidulant is present inside the powder particles and the surface is coated with an emulsifier. However, while this powder composition can suppress the formation of curds when a cup of milk is mixed in small amounts in several batches with the amount required to prepare one cup of beverage, it has the problem that curds are likely to form when the cup of milk is mixed all at once.

[0007] The present invention aims to provide an instant acidic beverage composition for preparing an acidic milk beverage by dissolving it in one or more types of milk selected from the group consisting of animal milk and plant milk, which inhibits the formation of curd when dissolved in milk all at once with only manual stirring and also inhibits solidification during storage, and a method for producing the instant acidic beverage composition. [Means for solving the problem]

[0008] As a result of extensive research aimed at solving the above problems, the present inventors have found that by incorporating dextrin and pectin and coating the surfaces of the solid particles with an organic acid, it is possible to suppress both solidification during storage and the formation of curd when the solid particles are dissolved all at once in milk, and have completed the present invention.

[0010] The present invention provides a powder composition for an instant acidic beverage for preparing an acidic milk beverage, which is resistant to solidification during storage and is resistant to the formation of curds even when dissolved all at once in one or more types of milk selected from the group consisting of animal milk and plant milk. Furthermore, the powder composition for an instant acidic beverage can be used to produce an acidic milk beverage. DETAILED DESCRIPTION OF THE INVENTION

[0011] In the present invention and the present specification, the term "animal milk" refers to mammalian milk. Examples of animal milk include cow's milk, goat's milk, sheep's milk, and horse's milk. In the present invention and this specification, the term "plant-based milk" refers to a liquid obtained by extracting components containing protein and fat from plant-derived raw materials such as beans, nuts, grains, etc. with water. Examples of plant-based milk include soy milk, peanut milk, almond milk, cashew nut milk, macadamia nut milk, walnut milk, coconut milk, rice milk, oat milk, and corn milk. In the present invention and this specification, "milk" is a general term for animal milk and plant milk.

[0012] In this invention and this specification, "powder" means a granular material (consisting of many solid particles with a distribution of different sizes, with some interaction between the individual particles). Also, "granules" are aggregates of particles (granular granulations) granulated from powder. Powder also includes granules.

[0013] In the present invention and this specification, the term "powder composition for instant acidic beverages" refers to a powdered composition that can be dissolved or dispersed in a liquid such as water or milk to prepare an acidic beverage. The term "acidic beverage" refers to a beverage with a pH of 5.5 or less.

[0014] In the present invention and the present specification, the term "acidic milk beverage" refers to an acidic beverage made primarily from milk. Examples of acidic milk beverages include beverages obtained by blending an acidulant with milk and, if necessary, also blending ingredients that impart flavor or taste, such as sweeteners, fruit juice, or flavorings. Specific examples include drinking yogurt, strawberry milk, lemon milk, and lassi.

[0015] The method for producing a powder composition for instant acidic beverages according to the present invention (hereinafter sometimes referred to as the "production method according to the present invention") is a method for producing a powder composition for instant acidic beverages for dissolving in milk to prepare an acidic milk beverage, and is characterized by preparing a powder mixture containing dextrin and pectin, and granulating the powder mixture with a binder liquid containing an organic acid. This method produces a powder composition consisting of powdery solid particles containing dextrin and pectin, at least a portion of whose surface is coated with an organic acid.

[0016] The powder composition obtained by the production method of the present invention (powder composition for instant acidic beverages of the present invention) has an organic acid present on the surface of its solid particles, so that curd formation is suppressed even when it is mixed all at once with a large amount of milk, and it dissolves easily even when mixed with milk by manual stirring. Note that manual stirring refers to stirring by hand using a spoon or the like. Furthermore, because the powder composition contains pectin, solidification during storage is suppressed, even though the surfaces of the solid particles are coated with an organic acid. In other words, the powder composition for instant acidic beverages produced by the production method of the present invention is an excellent powder composition for instant acidic beverages, in that the formation of curd is suppressed when it is dissolved all at once in milk by manual stirring alone, and solidification during storage is also suppressed.

[0017] The milk used to prepare an acidic milk beverage by dissolving the powder composition for an instant acidic beverage according to the present invention may be animal milk or plant milk. It may be one type of milk or a mixture of two or more types of milk. It may also be milk that has been subjected to various processes, such as reducing the amount of specific ingredients such as fat or lactose, or adding functional ingredients. It may also be milk prepared by dissolving powdered milk, such as skim milk powder or soy milk powder, in water.

[0018] Pectin includes HM (high methoxyl) pectin, which has an esterification degree (the proportion of methyl galacturonate in the entire pectin molecule) of 50% or more, and LM (low methoxyl) pectin, which has an esterification degree of less than 50%. The pectin used in the present invention may be either HM pectin or LM pectin, or a mixture of both. HM pectin is preferred over LM pectin as the pectin to be contained in the powder composition for instant acidic beverages according to the present invention, as it is less likely to gel in the presence of calcium ions and therefore produces a beverage with a smoother texture.

[0019] The pectin content of the powder composition for an instant acidic beverage according to the present invention is not particularly limited as long as it is an amount that can suppress solidification during storage. The pectin content of the powder composition for an instant acidic beverage according to the present invention is preferably 0.1 to 10% by mass, more preferably 0.5 to 5% by mass, and even more preferably 1 to 2% by mass, based on the total mass of the composition.

[0020] Dextrin is a substance obtained by decomposing starch by an enzymatic reaction or acid treatment to reduce its molecular weight. The degree of reduction in molecular weight is expressed by the DE (Dextrose Equivalent) value. The dextrin used in the present invention may be one with a low DE value and relatively little sweetness, or one with a high DE value and relatively strong sweetness. The DE value of the dextrin used in the present invention is preferably 4 to 40, more preferably 8 to 35, and even more preferably 9 to 30. The dextrin used in the present invention may be one obtained by decomposing starch by an enzymatic reaction or acid treatment and then subjecting it to various purification methods, or commercially available dextrin may also be used.

[0021] The dextrin content of the powder composition for instant acidic beverages according to the present invention is not particularly limited as long as it is an amount that allows sufficient amounts of pectin and organic acid to be contained. The powder composition for instant acidic beverages according to the present invention preferably contains 10 to 70% by mass of dextrin relative to the total mass of the composition, more preferably 25 to 65% by mass, and even more preferably 40 to 60% by mass. By containing a sufficient amount of dextrin, a powder composition that is less likely to solidify can be obtained.

[0022] The organic acid used in the present invention is not particularly limited as long as it is an organic acid used in foods and beverages. Furthermore, the organic acid contained in the powder composition for instant acidic beverages according to the present invention may be one type or two or more types. That is, the organic acid used as a raw material in the production method according to the present invention may be one type or two or more types. Examples of organic acids used in foods and beverages include citric acid, lactic acid, malic acid, succinic acid, acetic acid, tartaric acid, gluconic acid, glucono-delta-lactone, phytic acid, adipic acid, and ascorbic acid, and preferably one or more types selected from the group consisting of citric acid, malic acid, and lactic acid.

[0023] The organic acid content of the powder composition for instant acidic beverages according to the present invention is preferably an amount such that, when the powder composition is dissolved in milk, the pH of the milk becomes 5.5 or less, preferably 5.0 or less, and more preferably 4.5 to 5.5. The content of the organic acid in the powder composition for instant acidic beverages according to the present invention is preferably 1 to 6% by mass, more preferably 1 to 5.5% by mass, and even more preferably 1 to 3% by mass, based on the total mass of the composition.

[0024] The powder composition for instant acidic beverages according to the present invention preferably further contains a pH adjuster in addition to dextrin, pectin, and organic acid. The pH adjuster contained in the powder composition for instant acidic beverages according to the present invention is not particularly limited as long as it can be added to foods and beverages, but examples thereof include sodium salts of organic acids, potassium salts of organic acids, sodium salts of inorganic acids, and potassium salts of inorganic acids. Among these, sodium and potassium salts of citric acid, gluconic acid, succinic acid, acetic acid, lactic acid, malic acid, tartaric acid, phosphoric acid, and carbonate are preferred. The powder composition for instant acidic beverages according to the present invention may contain one or more pH adjusters.

[0025] The powder composition for an instant acidic beverage according to the present invention may further contain, in addition to dextrin, pectin, and organic acid, one or more members selected from the group consisting of emulsifiers and sweeteners.

[0026] The emulsifier contained in the powder composition for instant acidic beverages according to the present invention is not particularly limited as long as it can be added to foods and beverages, but one that is easily soluble in water is preferred. For example, an appropriate hydrophilic emulsifier can be selected from among food emulsifiers. Examples of the hydrophilic emulsifier include polyglycerol fatty acid esters, glycerol fatty acid esters, polyglycerol condensed ricinoleic acid esters, sucrose fatty acid esters, propylene glycol fatty acid esters, sorbitan fatty acid esters, enzymatically decomposed lecithin, and organic acid monoglycerides. The emulsifier contained in the powder composition for instant acidic beverages according to the present invention may be one type or two or more types.

[0027] The powder composition for instant acidic beverages according to the present invention contains a sweetener, enabling the production of an acidic milk beverage with an excellent balance of sweetness and sourness. The sweetener contained in the powder composition for instant acidic beverages according to the present invention is not particularly limited as long as it can be added to foods and beverages. It can be appropriately selected and used taking into consideration the desired product quality of the acidic milk beverage produced by dissolving the powder composition in milk. Specific examples of sweeteners contained in the powder composition for instant acidic beverages according to the present invention include sugars such as sugar, sucrose-type liquid sugar, oligosaccharides, and glucose-fructose liquid sugar; sugar alcohols such as erythritol, trehalose, and sorbitol; and high-intensity sweeteners such as aspartame, acesulfame potassium, sucralose, and stevia. The sugar may be granulated sugar, white sugar, or powdered sugar. The powder composition for instant acidic beverages according to the present invention may contain one type of sweetener or two or more types of sweeteners.

[0028] The powder composition for an instant acidic beverage according to the present invention may further contain other ingredients, such as flow improvers, excipients (excluding dextrin), thickeners (excluding pectin), antioxidants, salts (minerals), fruit juice, flavorings, etc., to the extent that the effects of the invention are not impaired.

[0029] Examples of flow improvers contained in the powder composition for an instant acidic beverage according to the present invention include processing preparations such as fine silicon oxide and tricalcium phosphate. The inclusion of a flow improver further improves the solidification resistance of the powder composition for an instant acidic beverage according to the present invention. The powder composition for an instant acidic beverage according to the present invention may contain one type of flow improver or two or more types of flow improvers.

[0030] Examples of excipients contained in the powder composition for instant acidic beverages according to the present invention include starch, starch hydrolysates (excluding dextrin), sugars, dietary fiber, etc. Examples of starch include edible starches such as tapioca starch, glutinous rice starch, rice starch, potato starch, wheat starch, corn starch, waxy corn starch, taro starch, and sago starch. These starches may also be subjected to processing such as hydroxypropylation, acetylation, and phosphoric acid monoesterification, or cross-linking. Examples of starch hydrolysates include powdered syrup and starch syrup. Examples of sugars include lactose, maltose, sucrose (sugar), trehalose, and oligosaccharides. Examples of dietary fiber include indigestible dextrin and cellulose. The powder composition for instant acidic beverages according to the present invention may contain one type of excipient or two or more types of excipients.

[0031] Examples of thickeners contained in the powder composition for instant acidic beverages according to the present invention include water-soluble dietary fibers (excluding pectin), such as soybean dietary fiber (soluble soybean polysaccharides), polydextrose, indigestible dextrin, galactomannan, inulin, guar gum, xanthan gum, gum arabic, and carboxymethylcellulose (CMC). The thickener contained in the powder composition for instant acidic beverages according to the present invention may be one type or two or more types.

[0033] In the production method of the present invention, a powder mixture containing dextrin and pectin is first prepared. This powder mixture is a raw material for granulation and serves as a granulation core for the powdered solid particles in the powder composition for an instant acidic beverage. In the present invention, the powder mixture may contain one type of powder raw material other than dextrin and pectin, or two or more types of powder raw materials other than dextrin and pectin. The powder raw materials other than dextrin and pectin are not particularly limited as long as they are powders. For example, it is preferable that the powder mixture further contains a sweetener, an excipient, etc. in addition to dextrin and pectin.

[0034] The binder liquid used in the production method according to the present invention is prepared by dissolving an organic acid in an aqueous solvent. The aqueous solvent may be any edible aqueous solvent, such as water or various buffer solutions, and is generally water.

[0035] The binder liquid preferably further contains a pH adjuster, and the presence of the pH adjuster together with the organic acid on the surfaces of the powdered solid particles in the powder composition for an instant acidic beverage more effectively suppresses the formation of curd when the composition is mixed with milk.

[0036] The content of the organic acid in the binder liquid can be appropriately adjusted taking into consideration the amount sprayed onto the granulation core, etc., so that the amount of organic acid contained in the entire powder composition obtained by spraying the binder liquid onto granulation cores consisting of the powder mixture and drying it is an amount that can adjust the pH of the milk in which the powder composition is dissolved to 5.5 or less, preferably 5.0 or less.

[0037] When the binder liquid contains a pH adjuster, the content of the pH adjuster in the binder liquid can be appropriately adjusted taking into consideration the amount sprayed onto the granulation cores, etc., so that the amount of pH adjuster contained in the entire powder composition obtained by spraying the binder liquid onto granulation cores made of the powder mixture and drying it falls within the desired range.

[0038] In addition to the organic acid and the pH adjuster, the binder liquid may contain one or more water-soluble components, such as an emulsifier and an excipient, within the range that does not impair the effects of the present invention.

[0039] The powder mixture is granulated using the binder liquid to produce solid particles (organic acid-coated granules) containing dextrin and pectin, which are the main components of the powder composition for instant acidic beverages according to the present invention, and at least a portion of the surface of which is coated with an organic acid. While known wet granulation methods such as fluidized bed granulation, tumbling granulation, and extrusion granulation can be used for the granulation, fluidized bed granulation is preferred because it produces granules with sufficient internal voids, improved wettability with water, and improved solubility in aqueous media such as milk. Fluidized bed granulation can be carried out by conventional methods using a commercially available fluidized bed granulator.

[0040] The organic acid-coated granules produced by the production method of the present invention may be used as a powder composition for an instant acidic beverage as is, or may be mixed with other powders to produce a powder composition for an instant acidic beverage. The powder composition for an instant acidic beverage thus obtained is resistant to solidification during storage, and even when mixed with a relatively large amount of milk at once, the formation of curd is suppressed and the solubility in milk is good.

[0041] Other powders that can be mixed with the organic acid-coated granules to produce the powder composition for an instant acidic beverage according to the present invention include flow improvers, flavors, sweeteners, minerals, excipients, etc. As these powders, those listed above can be used.

[0042] The powder composition for an instant acidic beverage containing the organic acid-coated granules produced by the production method of the present invention can be individually packaged in a small pouch or the like so that a single serving is consumed, or it can be packaged in a container such as a bottle so that several servings are consumed by shaking or spooning the beverage out of the container when consumed and supplied as a commercial product.

[0043] The individually packaged type is a stick-shaped aluminum pouch, a one-portion cup, etc., filled with the contents of one cup of cocoa drink. The individually packaged type has the advantage of being easy to handle and hygienic, as each cup is sealed. [Example]

Water was used as the solvent for the binder liquid. 500 g portions of the powder mixture and binder liquid were taken as prescribed and subjected to fluidized bed granulation using a fluidized bed granulator (FLO-1; manufactured by Freund Corporation). A portion of the granules obtained by granulation was used as the granules themselves as a powder composition for an instant acidic beverage. Part of the granulated granules was mixed with fine silicon oxide to prepare a powder composition for an instant acidic beverage.

[0046] <Solidification test> A caking test for examining the caking resistance of the powder composition was carried out as follows. First, 14 g (one serving) of the powder composition to be evaluated was stored in an aluminum three-sided pouch and stored for 8 hours in an environment of 60° C. Thereafter, the state of solidification of the powder composition was visually confirmed and evaluated according to the following criteria.

[0047] Solidification evaluation criteria 0 points: No solidification was observed. 1 point: Fine granular solidification can be seen in some areas. 2 points: Large granular solidification can be seen in some areas. 3 points: Several large solidified particles were observed, and few fine particles were observed. 4 points: All powder has solidified into one lump.

[0048] <Milk solubility test> A milk solubility test to examine the solubility of the powder composition in milk was carried out as follows. First, 14 g (one serving) of the powder composition to be evaluated was weighed into a 200 mL beaker, and 120 mL (one serving) of refrigerated milk was poured into the beaker. The mixture was manually stirred with a spoon at a speed of 120 rpm. The solubility in milk was evaluated based on the state of the mixture after stirring, according to the following criteria.

[0049] Milk solubility evaluation standard 0 points: High solubility (all powder was dissolved after 30 stirrings). 1 point: The solubility is somewhat high (all the powder was dissolved after 50 stirrings). 2 points: Solubility is slightly low (all the powder was dissolved after 70 stirrings). 3 points: Low solubility (after 70 stirrings, aggregates (curds) were observed and the solution was heterogeneous).

[0050] [Example 1] Powder compositions for instant acidic beverages were produced according to the formulations in Tables 1 to 3, and their solidification properties and milk solubility were examined.

[0051] In Tables 1 to 3, dextrin A (DE=9) is "Max 1000" (Matsutani Chemical Industry Co., Ltd.), dextrin B (DE=18) is "TK-16" (Matsutani Chemical Industry Co., Ltd.), dextrin C (DE=30) is "SPD" (Showa Sangyo Co., Ltd.), thickener A (HM pectin) is "YM-150-LJ" (Sansho Co., Ltd.), thickener B (LM pectin) is "LM-106AS-YA-J" (Sansho Co., Ltd.), and thickener C (guar gum) is "PROCOL The thickeners used were "Echo Gum RF" (manufactured by San-ei Gen F.F.I.), thickener D (xanthan gum) was "Echo Gum T / Keltrol T" (manufactured by San-ei Gen F.F.I.), thickener E (CMC) was "Sunrose F50MC" (manufactured by Nippon Paper Industries Co., Ltd.), diglycerin fatty acid ester was "DO-100V" (manufactured by Riken Vitamin Co., Ltd.), and microcrystalline silicon dioxide was "Silopage 720" (manufactured by Fuji Silysia Chemical Co., Ltd.).

[0052] [Table 1]

[0053] [Table 2]

[0054] [Table 3]

[0055] The powder compositions of Test Plots 1 to 13 and 16 to 18, in which an organic acid was added to the binder liquid, exhibited excellent milk solubility, and even when one cup of powder (14 g) was mixed all at once with one cup of milk (120 mL) and manually stirred, no curd formation was observed. In contrast, the powder compositions of Test Plots 14, 15, and 19, in which an organic acid was added to the dispersion mixture rather than the binder liquid, exhibited curd formation, confirming poor milk solubility.

[0056] The powder compositions of Test Plots 1 to 13, in which pectin was blended into the dispersion mixture, also had good resistance to solidification. In contrast, the powder composition of Test Plot 16, in which no pectin was blended, and the powder compositions of Test Plots 17 and 18, in which other thickeners were blended into the dispersion mixture instead of pectin, had very poor resistance to solidification.

[0057] Comparing the results of the powder compositions in Tests 1 to 13, it was found that the effects of improving milk solubility and caking resistance were achieved with both HM pectin and LM pectin, regardless of the type of organic acid. It was also confirmed that caking resistance was further improved by adding particulate silicon dioxide, a flow improver.
