Description

  The present invention relates to a powder composition for a water electrolyte supplement drink and a water electrolyte supplement drink.

The most common component of the human body by weight is water, accounting for 50-70% of body weight. It is essential to maintain the water content of the human body, as excessive dehydration of over 2% of body weight has been reported, including many reports of decreased endurance performance. Moreover, the osmotic pressure of plasma is in the range of 275-295 mOsm / kgH ₂ O, and it is necessary to keep the ratio of water and electrolyte constant. For this purpose, a water / electrolyte supplement beverage in which components are combined so that water and electrolyte can be replenished simultaneously is known (see, for example, Patent Document 1).

  On the other hand, when a person takes water or an electrolyte solution, the kidney functions to return the water content and electrolyte concentration of the human body to a certain balance. However, if a large amount of water or electrolyte solution is ingested at one time, there is a drawback in that the kidneys are burdened because their body balance is lost due to a rapid change in the concentration of water and electrolyte.

  Athletes are known to adopt a method called water loading that stores water and electrolytes in advance in order to compensate for any loss of water due to sweating. Ingestion is considered inappropriate, and it is considered useful to take small amounts over time. In addition, elderly people tend to have a lower moisture content in the body, and thus a lower proportion of moisture per body weight. For this reason, even if the amount of water in the body is slightly reduced, it tends to be dehydrated and it is desirable to frequently replenish water and electrolytes, but it is often difficult to replenish water and electrolytes on a daily basis. In this case as well, there is a need for a method that can retain moisture and electrolytes in the body without burdening the body even if a certain amount of moisture and electrolytes are consumed at once.

  The present invention solves the problem of burden on the body at the time of intake of water and electrolyte by relaxing the absorption rate of water and electrolyte in the small intestine after ingestion of the water electrolyte supplement drink, and can easily replenish water and electrolyte The purpose is to provide ingested goods.

As a result of diligent efforts to solve the above-mentioned problems, the present inventors have obtained a powder for water electrolyte supplemented beverage according to the present invention in which a certain amount of guar gum enzyme degradation product and a certain amount of sodium salt are added to the powder for water electrolyte supplemented beverage. The present inventors have found that the water and electrolyte absorption rate in the small intestine at the time of ingestion of a water electrolyte supplement drink obtained by hydrating can be reduced, and the burden on the body at the time of water intake can be reduced, and the present invention has been completed.
That is, the present invention relates to a powder composition for a water electrolyte supplement drink and a water electrolyte supplement drink.

  The powder composition for a water electrolyte replenishing beverage and the water electrolyte replenishing beverage of the present invention have an advantage that even if a large amount of water and electrolyte are ingested at one time, it is difficult to place a burden on the body. By using the powder composition for a water electrolyte replenishing beverage and the water electrolyte replenishing beverage of the present invention, it is possible to reduce the burden on the body at the time of taking the water electrolyte and replenish water and electrolyte.

Hereinafter, the present invention will be described in detail.
The powder composition for a water electrolyte supplemented beverage in the present invention contains 10 to 55%, more preferably 20 to 30%, of a guar gum enzyme degradation product, and is further considered to affect the water absorption rate. Contains 1.2 to 3.5% sodium salt, more preferably 1.3 to 2.7% sodium salt. If the concentration of the guar gum enzyme degradation product is low, the effect of reducing the absorption rate of moisture and electrolytes in the small intestine is not sufficient, and if the concentration is high, the viscosity of the beverage becomes high and there is a drawback that it is difficult for people to drink. Furthermore, it is more preferable to contain 0.2 to 0.4% of calcium salt as an equivalent amount of calcium.

  The water in the food and drink is divided into free water that easily moves and evaporates due to changes in the environment and temperature and humidity, and bound water that is strongly bound to proteins and carbohydrates that are ingredients of the food and drink. Due to its nature, bound water is considered to be slowly absorbed in the small intestine when ingested compared to free water. Examples of the carbohydrate that binds to water include a guar gum enzyme degradation product contained in the product of the present invention. The ratio of free water and bound water can be estimated by measuring the water activity when the water content in the food or drink is low. However, in the case of a beverage having a high water content such as the product of the present invention, it can be estimated by measuring the nuclear magnetic resonance of the beverage by NMR or MRI and measuring the water diffusion coefficient. The water diffusion coefficient in the water electrolyte supplemented beverage is not particularly limited, but it is preferably 75-95% and more preferably 80-90% when pure water is 100%. The method for measuring the water diffusion coefficient is not particularly limited, but the MRI method and the NMR method are usually used, and the MRI method is preferable for measuring an aqueous solution containing a plurality of components.

The absorption rate of water and electrolyte when the beverage of the present invention is ingested is related to the osmotic pressure of the water electrolyte supplemented beverage. Although method for measuring osmotic pressure are not particularly limited, can be conveniently measured by an automatic osmometer, osmotic pressure of the water electrolyte supplement drink is 180-250mOsm / kgH ₂ O is desirably are 200-230mOsm / kgH ₂ O It is more desirable.

  The method for measuring the electrolyte absorption rate is not particularly limited, but it can be measured by using an animal or the like and using a non-absorbable / non-fermentable chemical substance such as polyethylene glycol (PEG) as an index. For example, a water electrolyte supplemented beverage that has been added with polyethylene glycol is injected into the stomach with an oral sonde. The amount of absorption in the small intestine can be measured by subtracting the amount of PEG and electrolyte remaining in the stomach and small intestine from the amount of PEG and electrolyte injected into the stomach. When SD male rats are used, the water absorption rate in the small intestine is desirably 2.0 to 3.0 g / 8 minutes, and more desirably 2.2 to 2.7 g / 8 minutes. In the same manner, the absorption rate of sodium ions in the small intestine is preferably 45 to 75 μg / 8 minutes, and more preferably 55 to 70 μg / 8 minutes. When measured by this method, a commercially available general water electrolyte supplemented beverage has a water absorption rate of about 5-8 g / 8 minutes in the small intestine and a sodium ion absorption rate of about 150-190 μg / 8 minutes.

  The method for preparing the powder composition for a water electrolyte supplement beverage of the present invention is not particularly limited, such as the order of mixing the guar gum enzyme degradation product, sodium salt, and other components. Desirably 20-80 parts, more desirably 35-65 parts of the prepared powder composition for a water electrolyte replenishing beverage is dissolved in 1000 parts of water to prepare a water electrolyte replenishing beverage.

  The product of the present invention can contain inorganic substances such as potassium, calcium, chlorine, magnesium, citric acid, and phosphorus as other components. From the viewpoint of reducing the taste of the water electrolyte supplement beverage and the burden on the body, the concentration of the electrolyte component is as follows: potassium 1.2 to 2.4%, calcium 0.2 to 0.4%, chlorine 3. It is desirable to contain 5 to 4.5%, magnesium 0.05 to 0.15%, citric acid 4.8 to 9.6%, and phosphorus 0.05 to 0.2%. Furthermore, from the viewpoint of the taste of the water electrolyte supplemented beverage, it is desirable to contain a saccharide, and it is even more desirable to contain ascorbic acid. The carbohydrate is not particularly limited, but sucrose and glucose are preferable from the viewpoint of availability.

The guar gum enzymatic degradation product is produced by enzymatically degrading guar gum with β-galactomannanase derived from Aspergillus or Rhizopus, more preferably β-galactomannanase derived from Aspergillus, purifying and powdering.
Sodium salts are not particularly limited, but include sodium chloride, trisodium citrate, sodium acetate, sodium sulfate, sodium carbonate, sodium hydroxide, and the like. Sodium and trisodium citrate are preferred.

The raw materials for potassium, calcium, chlorine, magnesium, citric acid, and phosphorus are not particularly limited as long as they are food raw materials, but sodium chloride, potassium chloride, trisodium citrate, citric acid are easy to obtain. Tricalcium phosphate is desirable.
Examples of other components that can be used in combination include artificial sweeteners such as aspartame, acesulfame potassium, sucralose, and fragrance.

Pure water was measured for comparison.

The powder compositions of Example 1-3 and Comparative Example 1 were similarly dissolved in water, and the osmotic pressure was measured with an automatic osmometer.
Absorption of water and sodium ions by animal testing with rats was conducted by dissolving polyethylene glycol (hereinafter PEG) at a concentration of 2 g / L in each beverage in which the powder composition of Example 1-3 and Comparative Example 1 was similarly dissolved. The speed was compared.

  Eight-week-old SD male rats were divided into 6 groups (6 rats in each group), and about 9 ml of each test solution was injected via oral sonde under consciousness. Eight minutes after injection, the contents of the stomach and small intestine were collected. Based on the weight and PEG concentration in the contents of the stomach and small intestine, the residual amount and disappearance amount (water absorption amount) of the stomach and small intestine were calculated. Sodium ion concentration was measured using an ion chromatograph (761 Compact IC, Metrohm), and PEG concentration was measured according to the method of Malawer.

The water / sodium absorption rate in the small intestine was compared with Comparative Example 1 and a significant difference test was performed by Student's t test, and a risk rate of 5% or less was regarded as a significant difference.
