Description

The present invention relates to a dairy beverage with reduced salty taste while maintaining a constant sodium concentration, and a method for reducing the salty taste of a dairy beverage.

Against the background of recent health-consciousness and diversification of palatability, milk-based drinks have been developed to suit a wide variety of targets.For example, as disclosed in Patent Document 1, milk-based drinks with unique palatability A milk-based drink has been developed that has the appearance required for a sports drink while maintaining a good milky texture, and has high thirst-quenching properties that can quench your thirst and make it drinkable like a sports drink. ing.
In addition, when sweating due to exercise, etc., it has been recommended to replenish an appropriate amount of water and salt to prevent the sodium and water balance in the body from being disrupted, and sports drinks and oral rehydration solutions have been recommended. ing. In addition, oral rehydration solutions are used to maintain the balance of sodium and water in the body when a person is dehydrated due to diarrhea, vomiting, or fever due to a cold or the like. Furthermore, due to the effects of global warming in recent years, opportunities to be exposed to high temperature and/or high humidity environments have increased in daily life, resulting in an increase in health damage caused by heatstroke, and the Ministry of the Environment has As one of the useful preventive measures, adequate hydration and salt supplementation are widely advocated. As one measure to prevent heat stroke, it is recommended to take sports drinks or oral rehydration solutions containing 40 to 80 mg/100 ml of sodium as appropriate.

However, it is generally said that humans can perceive a salty taste from a sodium concentration of about 20 mg/100 ml, and if a high concentration of sodium is added, the salty taste becomes too strong, making it difficult to drink. Therefore, for example, in Patent Document 2, a salty functional drink containing at least one mineral component selected from the group consisting of calcium, magnesium, potassium, and sodium is added to an herb extract obtained from herbs by steam distillation or the like. A beverage is disclosed that can provide a balanced flavor while masking the salty taste by adding . Furthermore, in Patent Document 3, by adding a certain amount of trehalose to a salty beverage containing at least one mineral component selected from sodium, potassium, magnesium, and calcium, the salty taste caused by the mineral component can be reduced. Techniques for improving bitterness have been described. Furthermore, in Patent Document 4, in order to suppress the salty taste caused by metal ions and chloride ions generated from mineral components, D-psicose is added and the content ratio of chloride ions and D-psicose is adjusted. The technology is described.
From the above, there is a need to develop a beverage that contains a certain concentration of sodium, is drinkable, and has high palatability.

[7] A method for reducing the salty taste of a dairy beverage having a sodium concentration of 40 to 90 mg/100 ml and containing 0.5 to 2.0 mass% nonfat milk solids (SNF), comprising:
Including the step of adding magnesium so that the magnesium concentration is 2 to 7 mg / 100 ml,
A salty flavor for a milk-based beverage, which may include a step of adding potassium so that the potassium concentration is 10 to 20 mg/100 ml, and/or a step of adding calcium so that the calcium concentration is 8 to 15 mg/100 ml. Reduction method.

The present invention can provide a new milk-based beverage that maintains a sodium concentration of 40 to 90 mg/100 ml, has a reduced salty taste, and does not impair the palatability and good milk feel characteristic of milk-based drinks.

The present invention provides a dairy product containing 0.5 to 2.0% by mass non-fat milk solids (SNF), a sodium concentration of 40 to 90 mg/100 ml, and a magnesium concentration of 2 to 7 mg/100 ml. Regarding beverages. The milky beverage preferably has a potassium concentration of 10 to 20 mg/100 ml, and preferably a calcium concentration of 8 to 15 mg/100 ml.
The dairy beverage of the present invention contains a milk component. The milk component of the milky beverage may be anything that contains non-fat milk solids, and its origin and form of raw materials are not limited. For example, the milk component may be derived from either animal milk or vegetable milk. Examples of animal milk include cow's milk, goat's milk, sheep's milk, and horse's milk, and examples of plant milk include soy milk. Examples of the form of milk components include whole fat milk, skim milk, whey, milk protein concentrate, buttermilk powder, evaporated milk, skim sweetened condensed milk, whole fat sweetened condensed milk, fresh cream, and fermented milk. . Milk reconstituted from powdered milk or concentrated milk can also be used. Among these, skim milk is preferred, and skim milk powder is particularly preferred because of its ease of handling. Further, the milk component may be derived from a single type of raw material or from multiple types of raw materials. Furthermore, as the milk component, acidic milk obtained by fermenting raw milk using lactic acid bacteria and yeast to form a liquid or paste may be used.
The dairy beverage of the present invention contains 0.5-2.0% by weight non-fat milk solids (SNF), more preferably 0.6-1.0% by weight SNF. When the content of SNF is less than 0.5% by mass, it is difficult to obtain the salty taste reducing effect, and there is a possibility that the palatability and milky taste as a milk-based beverage may not be imparted. On the other hand, if the content of SNF exceeds 2.0% by mass, the milk flavor will become strong, and the thirst quenching property may be reduced in terms of drinking in large quantities. The content of SNF can be adjusted by adjusting the form and amount of milk used as a raw material, and can be determined, for example, by calculation based on the raw materials used in production or by a general standard method such as the Kjeldahl method. Note that the milk solid content (total amount of SNF and milk fat content) contained in the dairy beverage may be less than 3% by mass.

The sodium concentration of the dairy beverage of the present invention is 40 to 90 mg/100 ml, more preferably 50 to 60 mg/100 ml. If the sodium concentration is less than 40 mg/100 ml, there is a risk that the amount of sodium suitable for preventing heatstroke may not be provided to the person taking it, and if it exceeds 90 mg/100 ml, the salty taste will be too strong and it will be difficult to drink. There is a risk that it will happen. The sodium contained in the milk beverage can be adjusted by adding a sodium salt while considering the amount of sodium derived from milk components, for example, skim milk powder. As sodium salts, for example, sodium chloride, sodium citrate, sodium bicarbonate, sodium malate, sodium tartrate, sodium lactate, sodium gluconate, sodium ascorbate, sodium glutamate, sodium aspartate, etc. can be used. The sodium in the milk drink of the present invention is preferably derived primarily from sodium chloride, and particularly preferably from common salt containing sodium chloride. The salt to be used is not particularly limited as long as it is salt used for food such as natural salt, rock salt, sea salt, and refined salt. The milky beverage of the present invention contains 0.07 to 0.2% by mass/volume of sodium chloride, more preferably 0.1 to 0.15% by mass/volume of sodium chloride, and has a sodium concentration of 40 to 40% by volume. Preferably it is 90 mg/100 ml. By containing 0.07 to 0.2% by mass/volume of sodium chloride, the milk-based beverage of the present invention has the advantage that a more natural flavor can be obtained and a milk-based beverage with high palatability can be obtained. The sodium concentration of the present invention can be, for example, a value theoretically calculated from the amount of sodium salt added in the beverage.

The magnesium concentration of the milk drink of the present invention is 2 to 7 mg/100 ml, more preferably 3 to 6 mg/100 ml. If the magnesium concentration is less than 2 mg/100 ml, there is a risk that the salty taste of the milk beverage cannot be sufficiently suppressed, and if it exceeds 7 ml/100 ml, there is a risk that mineral tastes such as bitterness and astringency will become stronger. Magnesium in the milk beverage of the present invention can be adjusted by adding magnesium salt in addition to magnesium derived from milk components. Examples of magnesium salts include magnesium chloride, magnesium chloride hexahydrate, magnesium L-glutamate, magnesium silicate, magnesium oxide, magnesium hydroxide, magnesium stearate, magnesium carbonate, magnesium sulfate, trimagnesium phosphate, and phosphorus. Magnesium monohydrogen acid and the like can be used. It is preferable that the magnesium in the milk drink of the present invention is mainly derived from magnesium chloride hexahydrate. The magnesium concentration of the present invention can be, for example, a value theoretically calculated from the amount of magnesium salt added in the beverage.

The potassium concentration of the milk drink of the present invention is 10 to 20 mg/100 ml, more preferably 11 to 15 mg/100 ml. If the potassium concentration is less than 10 mg/100 ml, it may not be possible to sufficiently suppress the salty taste of the milk drink, and if it exceeds 20 ml/100 ml, there is a risk that mineral taste such as salty taste will become stronger. The potassium content of the milk-based beverage of the present invention can be adjusted by adding potassium salt in addition to the potassium derived from milk components. Examples of potassium salts include potassium alginate, potassium chloride, monopotassium citrate, tripotassium citrate, potassium gluconate, potassium L-glutamate, potassium DL-bitartrate, potassium hydrogentartrate, potassium nitrate, potassium hydroxide, Potassium sorbate, potassium carbonate, potassium lactate, norbixin potassium, potassium pyrosulfite, tetrapotassium pyrophosphate, potassium ferrocyanide, potassium polyphosphate, potassium metaphosphate, potassium aluminum sulfate, potassium sulfate, tripotassium phosphate, hydrogen phosphate Dipotassium, potassium dihydrogen phosphate, etc. can be used. It is preferable that the potassium in the milk drink of the present invention is mainly derived from potassium chloride. The potassium concentration of the present invention can be, for example, a value theoretically calculated from the amount of potassium salt etc. added in the beverage.

The calcium concentration of the dairy beverage of the present invention is 8 to 15 mg/100 ml, more preferably 9 to 12 mg/100 ml. If the calcium concentration is less than 8 mg/100 ml, there is a risk that the salty taste of the milk beverage cannot be sufficiently suppressed, and if it exceeds 15 ml/100 ml, there is a risk that the mineral taste such as a coarse taste will be strong. Calcium in the milk drink of the present invention can be adjusted by adding calcium salts in addition to calcium derived from milk components. Examples of calcium salts include L-calcium ascorbate, calcium alginate, calcium chloride, calcium carboxymethyl cellulose, calcium lactate, calcium citrate, calcium gluconate, calcium L-glutamate, calcium silicate, calcium acetate, calcium saccharin, and calcium chloride. Calcium, calcium hydroxide, calcium stearate, calcium stearoyl lactate, calcium sorbate, calcium carbonate, calcium pantothenate, calcium dihydrogen pyrophosphate, calcium ferrocyanide, calcium propionate, calcium sulfate, tricalcium phosphate, monophosphate Calcium hydrogen, calcium dihydrogen phosphate, etc. can be used. It is preferable that the calcium in the milk drink of the present invention is mainly derived from calcium lactate. The calcium concentration of the present invention can be, for example, a value theoretically calculated from the amount of calcium salt etc. added in the beverage.

In the present invention, the sugar content of a milky beverage is synonymous with the Brix (also expressed as Brix or Bx) value. That is, in the present invention, the sugar content is the reading of a sugar refractometer at 20°C, for example, the solid content measured at 20°C using a brand name "Digital Refractometer Rx-5000" (manufactured by Atago). be able to. The sugar content is preferably 3 to 13°, more preferably 5 to 10°. Furthermore, the degree of sweetness of the milk beverage as an evaluation of palatability is preferably from 4 to 9, particularly preferably from 5 to 7. When the sweetness level is less than 4, it is difficult to obtain the salty taste reducing effect, and there is a possibility that the palatability as a milk-based drink may not be imparted. On the other hand, if the sweetness level is more than 9, although the effect of reducing the salty taste can be obtained, there is a risk that the drinkability will be lowered. In the present invention, the degree of sweetness is defined, for example, by the method described in the Examples below.
The sugar content and sweetness level in the present invention can be adjusted to the above values by using a known sweetener. For example, sugars such as sucrose, glucose, granulated sugar, fructose, lactose, and maltose, high-fructose corn syrup, and high-fructose corn syrup; low-intensity sweeteners such as xylitol, D-sorbitol; thaumatin, stevia extract, glycyrrhizin It is preferable to adjust high-intensity sweeteners such as acid disodium, acesulfame potassium, sucralose, aspartame, saccharin, neotame, and saccharin sodium singly or in combination of two or more as appropriate; Adjustment with acesulfame potassium, sucralose, and aspartame is particularly preferable from the viewpoint of palatability such as the natural sweetness and refreshing sourness required for dairy drinks. Furthermore, from the viewpoint of improving thirst quenching properties (drinkability in gulps), it is more preferable to keep the sweetness level as low as possible without using a high-intensity sweetener. Furthermore, the sugar content and sweetness level may be adjusted by adding fruit juice, vegetable juice, etc. that may contain sugar content.

In the present invention, the sweetness level of a beverage is a parameter indicating the intensity of sweetness of the beverage, and is expressed as a relative value when the sweetness level of sucrose is 1. Calculated based on "sweetness level". Specifically, it is identified by the following method.
An aqueous solution is prepared for each sweetener contained in the beverage, and a concentration X that provides the same sweetness as a 1% by mass sucrose aqueous solution is determined. Then, "1 (mass %)/X (mass %)" is determined, and this value is defined as the "sweetness level of each sweetener." The total value of the "sweetness level of each sweetener" contained in the beverage is the "sweetness level of the beverage."
In addition, specific values of the sweetness degree of the sweetener that can be used in the present invention are described below.
Sucrose: 1
Fructose: 1.2
Glucose: 0.6
Fructose glucose liquid sugar (55% isomerized sugar): 0.75
Acesulfame potassium: 200
Sucralose: 600
Aspartame: 200

The milk drink of the present invention may contain citric acid and/or phosphoric acid as an acidulant. Citric acid and/or phosphoric acid may be added to milk drinks as their salts. Citric acid is preferably added as anhydrous citric acid, and as the citrate salt sodium citrate, especially trisodium citrate, can be used. As the phosphoric acid, liquid phosphoric acid (85%) and salts such as disodium hydrogen phosphate (anhydrous) can be used. The citric acid concentration in the milk drink is preferably 0.04 to 0.3% by mass/volume, more preferably 0.07 to 0.3% by mass/volume, and 0.1 to 0% by mass/volume. More preferably, it is .25% by weight/volume. Further, the phosphoric acid concentration in the milk drink is preferably 0.04 to 0.3% by mass/volume, more preferably 0.07 to 0.3% by mass/volume, and 0.1% by mass/volume. More preferably, it is 0.25% by mass/volume. When the milk drink contains both citric acid and phosphoric acid, the combined amount is preferably 0.04 to 0.3% by mass/volume, and 0.07 to 0.3% by mass/volume. It is more preferable that the content is 0.1 to 0.25% by mass/volume.

It is more preferable that the milk drink of the present invention contains lactic acid and/or malic acid in addition to citric acid and/or phosphoric acid as a sour agent. Lactic acid and/or malic acid may be added to milk drinks as their salts.
In addition, fruit juices such as citrus fruit juices such as oranges, lemons, and grapefruits, grapes, peaches, and apples may be used as optional acidic ingredients as long as they do not impair the effects of the present invention or the specified physical properties. , fruit juice such as banana may be added.

In the milk-based beverage of the present invention, the amount of acidulants such as citric acid, phosphoric acid, lactic acid, and malic acid is adjusted so that the acidity is 0.1 to 0.3% by mass. The content is preferably set to 0.15 to 0.25% by mass. By adjusting the acidity within this range, there is an advantage that it has the refreshing sour taste required for dairy drinks. In the present invention, acidity corresponds to citric acid acidity, and is defined, for example, by the method described in the Examples below.

In addition, in the milk-based beverage of the present invention, the chlorine ion content (in terms of mass) is greater than the sodium content (in terms of mass), and by having such a composition, the salty taste is suppressed and the flavor as a beverage is improved. It has the advantage of being well balanced.

Furthermore, the dairy beverage of the present invention may contain various flavors such as fruit flavors and plant flavors as additives, but it is particularly preferable to include yogurt flavor. In order to bring out the milk taste in the milk-based drink of the present invention, when the milk-based drink is made to have a flavor similar to that of yogurt, a particularly salty taste reduction effect can be obtained, improving the yogurt flavor and providing a good milky texture. While achieving this goal, it is possible to provide a milk-based beverage with a good aftertaste and high palatability.

The milky beverage of the present invention has a pH of 3.0 to 4.5, preferably 3.3 to 3.9. If the pH exceeds 4.5, the stability of milk proteins may be impaired and precipitation may increase; if the pH is less than 3.0, the sour taste may be felt strongly, making it less drinkable. In addition, there is a risk that the milk flavor of milk-based beverages may deteriorate more easily during storage.

Moreover, it is preferable that the milk-based beverage of the present invention contains a milk protein stabilizer. As the stabilizer, any thickening polysaccharide that can be used in foods and beverages can be used without particular limitation, but soybean polysaccharide is particularly preferred. Thickening polysaccharides may be used alone or in combination of two or more.
Soybean polysaccharides are water-soluble polysaccharides obtained from soybeans, and the main component is hemicellulose, which is further composed of saccharides such as galactose, arabinose, galacturonic acid, rhamnose, xylose, fucose, and glucose. This soybean polysaccharide can be obtained by extracting, refining, and sterilizing okara (fibrous pomace) produced during the production of soybean oil and isolated soybean protein from soybeans. In addition, commercially available soybean polysaccharides may be used, such as the product name "SM-700", the product name "SM-900", and the product name "SM-1200" (all of which are manufactured by San-Eigen F.F. (manufactured by Ai Co., Ltd.).
The blending ratio of the milk protein stabilizer can be appropriately determined depending on the type thereof, etc., within a range that does not impair the effects of the present invention. The lower limit of the mixing ratio is usually 0.01 based on the total mass of the drink, in order to maintain the stability of milk protein well and obtain a good appearance as an anti-thirst drink. Mass/volume %, preferably 0.05 mass/volume %, the upper limit of which is usually 0.3 mass/volume %, preferably 0.2 mass/volume %. If the blending ratio of the stabilizer is increased, the flavor and texture peculiar to the stabilizer may become stronger.
The water used in the present invention is not particularly limited, and for example, ion exchange water can be used.

The present invention also provides a method for reducing the salty taste of a dairy beverage having a sodium concentration of 40 to 90 mg/100 ml and containing 0.5 to 2.0 mass% nonfat milk solids (SNF), the method comprising: It includes a step of adding magnesium so that the concentration is 2 to 7 mg/100 ml, a step of adding potassium so that the potassium concentration is 12 to 20 mg/100 ml, and/or a step of adding potassium so that the concentration is 9 to 15 mg/100 ml. The present invention also relates to a method for reducing the salty taste of a dairy beverage, which may include the step of adding calcium to a volume of 100 ml. The amount of each component added is as described above.

The dairy beverage of the present invention has a sodium concentration of 40 to 90 mg/100 ml, and a magnesium concentration in a dairy beverage containing 0.5 to 2.0 mass% milk solids nonfat (SNF), and as necessary. By adjusting the potassium concentration and/or calcium concentration accordingly, and including citric acid and/or phosphoric acid and lactic acid and/or malic acid as acidulants as necessary, an unexpected salty taste reduction effect can be provided. At the same time, it is possible to maintain excellent palatability (good aftertaste, ease of drinking, favorable milk taste, etc.). Furthermore, since the milk-based beverage according to the present invention has a certain amount of sodium concentration, it is not only delicious, but can also be ingested for the purpose of preventing the sodium and water balance in the body from being disrupted due to sweating or the like.

In addition, in the milk-based beverage of the present invention, homogenization treatment and sterilization treatment can be added as appropriate and necessary in the manufacturing process.
Homogenization treatment can usually be performed using a homogenizer. Homogenization conditions are not particularly limited, but conditions of a temperature of 5 to 25°C and a pressure of 10 to 50 MPa are preferred. Further, the homogenization treatment is preferably performed before the sterilization treatment.
The sterilization treatment can be performed, for example, by heat sterilization at 65° C. for 10 minutes, which has a sterilization value equal to or higher than that. The method of sterilization treatment is not particularly limited, and methods such as ordinary plate sterilization, tubular sterilization, retort sterilization, batch sterilization, and autoclave sterilization can be employed.
Methods for filling containers with the milky beverage of the present invention after sterilization include, for example, hot-packing the beverage into containers and cooling the filled container, or cooling the beverage to a temperature suitable for filling the container. This can be carried out by aseptically filling containers that have been previously cleaned and sterilized.
