Description

  The present invention relates to a hermetically sealed beverage containing fat-soluble vitamins, a method for producing the same, and a method for stabilizing fat-soluble vitamins in beverages filled in hermetically sealed containers.

  Vitamins are neither a component of the body nor a source of energy, but these are essential enzyme action, metabolic regulation action, physiological action, etc. for conducting healthy activities. It has been known for a long time to have a very important relationship. Therefore, taking these vitamins appropriately is extremely important for maintaining and improving health, and with the recent increase in health orientation, vitamins were included to intentionally compensate for this. Many foods and drinks have been proposed.

  Vitamins are classified into fat-soluble vitamins such as vitamins A, D and E, and water-soluble vitamins such as vitamins B and C, but fat-soluble vitamins have been reported to be easily adsorbed by plastics. Therefore, when fat-soluble vitamins are blended in various foods and drinks, filled in plastic containers and stored for a long time, fat-soluble vitamins are adsorbed to the container, and the content of fat-soluble vitamins decreases over time. There was a problem.

  As a means for preventing such fat-soluble vitamins from adsorbing to the container, adsorption using acrylonitrile resin, ethylene-vinyl alcohol copolymer laminated glass container, and aluminum packaging material A method for preventing adsorption (Patent Document 1), a method of using a plastic containing polyethylene naphthalate in a portion in contact with the composition in a container filled with a composition containing fat-soluble vitamins (Patent Document 2) ) Etc. have been reported. However, it is not preferable to perform special processing on the container because it increases costs.

  On the other hand, the present applicants add polyglycerin fatty acid ester and lecithin to a packaged beverage containing fat-soluble vitamins as a means for preventing the adsorption of fat-soluble vitamins to the container without modifying the container. Report a method for stabilizing fat-soluble vitamins (Patent Document 3). However, since lecithin may affect the flavor of the product, the amount used may have to be limited, and further improvement has been demanded.

  Furthermore, in the beverage of the present invention, various existing substances having an antioxidant action can be blended for the purpose of suppressing deterioration of fat-soluble vitamins. Examples of the substance having an antioxidative action include ascorbic acid, sodium ascorbate, erythorbic acid, sodium erythorbate and the like, and ascorbic acid and sodium ascorbate are particularly preferable. The amount of the substance having an antioxidative action added to the beverage of the present invention is not particularly limited, but is usually about 0.01% to 0.07%, preferably about 0.01% to 0.05%. do it.

  There is no restriction | limiting in particular in the mixing | blending order and mixing method for manufacturing this invention drink, It can manufacture by a well-known method. That is, the beverage of the present invention is prepared by appropriately mixing fat-soluble vitamins and polyglycerin unsaturated fatty acid ester having an unsaturated fatty acid as a constituent fatty acid with optional components necessary for beverage production, sterilizing, and filling a sealed container. Can be manufactured.

  Polyglycerin unsaturated fatty acid ester having unsaturated fatty acid added to the beverage of the present invention as a constituent fatty acid is generally generally used as a food emulsifier, and has the ability to dissolve fat-soluble vitamins in water. It is also possible to use it as a raw material for the emulsification treatment performed to improve it. Therefore, before blending this into the beverage of the present invention, all or part of the polyglycerin unsaturated fatty acid ester having an unsaturated fatty acid as a constituent fatty acid is mixed with fat-soluble vitamins in advance and emulsified. Also good.

  In addition, the effect which inhibits adsorption | suction to the container inner surface of the fat-soluble vitamin of this invention drink is acquired even if it mix | blends polyglycerin unsaturated fatty acid ester which uses unsaturated fatty acid as a constituent fatty acid. Therefore, the beverage of the present invention is preferably prepared by mixing fat-soluble vitamins and polyglycerin unsaturated fatty acid ester having an unsaturated fatty acid as a constituent fatty acid together with an optional component from the viewpoint that workability is not complicated. .

  EXAMPLES Hereinafter, although an Example is given and this invention is demonstrated further in detail, this invention is not restrict | limited at all by these Examples.

Example 1
Preparation of hermetically sealed beverage:
Fructose-glucose liquid sugar (H-100; manufactured by Nippon Shokuhin Kako Co., Ltd.) 120 g, fermented milk (manufactured by Yakult Honsha) 17 g, skim milk powder (manufactured by Yotsuba Milk Industry Co., Ltd.) 6 g, anhydrous citric acid (manufactured by Junsei Chemical Co., Ltd.) 1.5 g, soybean Polysaccharides (SM-1200; manufactured by San-Ei Gen FFI Co., Ltd.) 1.5 g, flavors (produced by Yakult Materials Co., Ltd.) 1.5 g, and vitamin D preparation (Dry D ₃ -S50T; manufactured by Riken Vitamin Co., Ltd.) 0.016 g The emulsifiers shown in Table 1 were mixed, and purified water was added to make the total amount 1000 g. Next, homogenization was performed with a homogenizer (H20 type; manufactured by Sanwa Kikai Co., Ltd.) under conditions of 15 MPa, followed by sterilization at 90 ° C. for 10 seconds using an HTST sterilizer (model 25HV; manufactured by Micro Thermics). Immediately cooled to obtain a beverage.

  The beverage obtained above is aseptically filled in a paper container (made by Nippon Paper Pack Co., Ltd.) whose inner surface is coated with polyethylene so as not to enter air, and then heat-sealed, and a sealed container-packed beverage (practical product 1, 2 and comparative products 1 and 2) were obtained. About these sealed container-packed drinks, the vitamin D content in the drinks immediately after production and after storage for 1 month at 37 ° C. was measured. The results are also shown in Table 1. The vitamin D content was measured by a conventional method using high performance liquid chromatography (LC-10A series; manufactured by Shimadzu Corporation).

  As shown in Table 1, hermetically sealed beverage containing vitamin D, which is a fat-soluble vitamin, and polyglycerin unsaturated fatty acid ester containing oleic acid, which is an unsaturated fatty acid, as a constituent fatty acid (Examples 1 and 2) , The decrease in vitamin D content due to storage at 37 ° C. for 1 month was suppressed. On the other hand, the vitamin D content of vitamin D, which is a fat-soluble vitamin, and a sealed container-packed beverage (Comparative Product 1) containing a polyglycerin saturated fatty acid ester containing stearic acid, which is a saturated fatty acid, as a constituent fatty acid The effect of suppressing the decrease was not recognized. Moreover, about the product 1 and 2, when flavor evaluation was performed after one month preservation | save at 37 degreeC, all had favorable flavor.

  ADVANTAGE OF THE INVENTION According to this invention, the reduction | decrease of the fat-soluble vitamins with time by the preservation | save of the sealed container-packed drink containing fat-soluble vitamins can be suppressed.

Therefore, the present invention can be used as a beverage for supplementing fat-soluble vitamins that are extremely important in maintaining and promoting health.
