Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for reducing the bitterness of a magnesium salt useful for foods and medicines, and more particularly, to a method for reducing the bitterness of polyglycerin-condensed ricinoleate with fats and oils. The present invention relates to a method for reducing the bitterness of a magnesium salt, which comprises adding an aqueous solution of a magnesium salt to a mixture, mixing and then emulsifying the mixture to form a water-in-oil emulsion. In the present invention, the term "magnesium salt" means one or a mixture of two or more of magnesium chloride, magnesium sulfate and a substance containing magnesium chloride. This magnesium chloride-containing substance is the remainder obtained by separating and separating a salt portion from seawater, and the main component is magnesium chloride. [0003] In recent years, Japanese dietary habits are rich and excellent in terms of nutritional balance. However, according to the Ministry of Health and Welfare's annual National Nutrition Survey, magnesium, along with calcium, has not reached its target intake of 300 mg / day. It is also said that magnesium deficiency may cause myocardial infarction, angina, and hypertension due to contraction of blood vessels. Therefore, active intake of magnesium has been proposed. [0004] Magnesium chloride and magnesium sulfate have attracted attention as materials to compensate for such magnesium deficiency.
Widely used in food, but due to its inherent bitterness,
In order to reduce the commercial value of a product, its usage is limited, and the expansion of its use is restricted. As a method of reducing the bitterness of a bitter substance such as a magnesium salt, for example, a method of adding a sweetener (aspartame) and a flavoring agent (JP-A-2-56416), a method of adding a cyclodextrin (JP-A-Hei. JP-A-3-236316), a method of adding an alginate (JP-A-4-235136), and a method of adding a gelling agent and a flavoring agent to form a seasoned jelly (JP-A-4-346937). Of adding a glycerin diester of a fatty acid (JP-A-7-5
No. 3416), lecithin (phosphatidylcholine)
(JP-A-62-265234). However, there are many problems that it is difficult to reduce the bitterness of the magnesium salt sufficiently by any of the methods and that the taste quality of the food is easily changed. [0005] Therefore, there is a strong demand for a method for industrially advantageously reducing the bitterness of magnesium salts. The present invention addresses this need,
The details will be described below. The present inventors have made intensive studies to solve the above-mentioned problems, and as a result, added an aqueous solution of magnesium salt to a mixture of polyglycerin condensed ricinoleate and fats and oils. Then, emulsification was carried out to obtain a water-in-oil emulsion, and a method for industrially advantageously reducing the bitterness of the magnesium salt was found, and the present invention was completed. The polyglycerin condensed ricinoleate used in the present invention includes, for example, a condensation reaction of glycerin, a direct synthesis from epichlorohydrin, a method using glycidol, a method using a distillation residue of glycerin,
The polyglycerin and ricinoleic acid (castor oil fatty acid) produced by others are heated and dehydrated to condense 3 to 6 molecules, and then esterified and synthesized. As the polyglycerin condensed ricinoleate, commercially available products (for example, trade name: Sunsoft No.
818H, no. 818DG, no. 818SX manufactured by Taiyo Kagaku Co., Ltd., trade name: SY Glister-CR-300,
(CR-500, CR-ED, manufactured by Sakamoto Yakuhin Kogyo Co., Ltd., trade name: Step PR-6 Kao Food Co., Ltd., etc.)
Can be used freely. The fats and oils used in the present invention include vegetable oils such as corn oil, cottonseed oil, palm oil, coconut oil, soybean oil, rapeseed oil, rice oil, sesame oil, sunflower oil, safflower oil and cocoa butter. Animal fats and oils such as beef tallow, milk fat, lard fat, lard, fish oil, whale oil, etc., and hydrogenation and fractionation of these vegetable fats and animal fats,
One or more fats and oils selected from the group consisting of processed fats and oils which have been subjected to one or more treatments of ester conversion. Next, the production process of the present invention will be described. First, one or a mixture of two or more of magnesium chloride, magnesium sulfate and a substance containing magnesium chloride is added to water to prepare a magnesium salt aqueous solution. At this time, the magnesium salt has a concentration as high as possible, and a saturated aqueous solution is preferable. This is because the addition efficiency is good when adding to foods and pharmaceuticals. If the temperature of the aqueous solution of magnesium salt is equal to or higher than the precipitation temperature of the magnesium salt, for example, if the precipitation temperature of the magnesium salt is 40 ° C., the temperature of the aqueous solution is reduced by about 5 to 10
Maintain a temperature of 45-50 ° C, which is a high temperature. This aqueous magnesium salt solution is added to and mixed with a mixture of polyglycerin-condensed ricinoleate and fats and oils, followed by emulsification to obtain a water-in-oil emulsion. The emulsion particle size at the time of emulsification is preferably 10 μm or less, and more preferably 5 μm or less. 10μ
When the emulsified particle diameter is not less than m, the aqueous phase and the oil phase are separated during storage of the emulsion, resulting in poor stability. Further, the temperature of the mixture of the polyglycerin condensed ricinoleate and the fat or oil must be equal to or higher than the magnesium salt precipitation temperature of the magnesium salt aqueous solution when mixed with the magnesium salt aqueous solution. In the following cases, the magnesium salt in the aqueous magnesium salt solution precipitates upon cooling, and a good emulsion cannot be obtained, so that the bitterness of the magnesium salt cannot be reduced. A known method is used for the emulsification operation. For example, a method using a stirrer such as a propeller type stirrer or a turbine type stirrer, a homogenizer method, an ultrasonic method and the like can be mentioned. In this emulsion, precipitation of the magnesium salt does not occur even if the emulsion is cooled to a temperature lower than the magnesium salt precipitation temperature of the aqueous magnesium salt solution used. The amount of the polyglycerin-condensed ricinoleate used may be in the range of 8 to 80 parts (parts by weight, hereinafter the same) with respect to 100 parts of water used in the mixed system of the magnesium salt and water, and is preferably used. , 10 to 50 parts. When the amount is less than 8 parts, the aqueous solution of magnesium salt cannot be sufficiently emulsified, and the effect of reducing bitterness is hardly obtained.
If the amount is more than 80 parts, an unpleasant taste due to the polyglycerin condensed ricinoleate is felt, and the taste of the food product is deteriorated. The amount of oil and fat used is
The total amount of the polyglycerin condensed ricinoleate and the fat or oil may be 50 parts or more based on 100 parts of water used.
Preferably it is in the range of 80 parts to 150 parts. 5 used
If the amount is less than 0 parts, the emulsifiability of the aqueous magnesium salt solution with the polyglycerin condensed ricinoleate is poor,
The bitterness of magnesium salt cannot be reduced. As described above, a magnesium salt aqueous solution is added to a mixture of polyglycerin condensed ricinoleate and fats and oils, and the mixture is emulsified to form a water-in-oil emulsion. Can be reduced. Here, the object of the present invention has been achieved.
Hereinafter, the present invention will be described in detail with reference to Examples, but the present invention is not limited thereto. EXAMPLE 1 Magnesium sulfate (crystal) (50 parts) was dissolved in water (20 parts) at 70 ° C. to obtain a high concentration magnesium salt aqueous solution (magnesium sulfate precipitation temperature was about 60 ° C.) While maintaining the temperature at 70 ° C., 2 parts of various emulsifiers (see Table 1) and 28 parts of corn oil were mixed, and gradually added to the mixture maintained at 70 ° C., while adding a homomixer (special machine chemical Co., Ltd.) And emulsified, and a water-in-oil emulsion having an emulsified particle size of 0.1 to 5 μm and a magnesium sulfate (crystal) content of 50% (the same applies to the weight% or less) (products of the present invention and test products: these ) And kept at 20 ° C. Separately, an aqueous solution of 0 to 50% (1% interval) of magnesium sulfate (control product: this) was prepared and kept at 20 ° C. Then age 1
In a blinded test, 30 panelists aged 9 to 35 years old were allowed to select which bitterness of the emulsion using the emulsifier corresponded to the bitterness of the aqueous magnesium sulfate solution at the highest concentration. However, the concentration was adjusted to the bitterness of the emulsion. The bitterness reduction rate at that time was determined by the following equation. Reduction rate of bitterness (%) = 100− (salt concentration of magnesium (%) / salt concentration of magnesium (%)) × 10
0 The prepared emulsion was allowed to stand at 20 ° C. for 30 days, and its stability (the number of days until the emulsion separated into an aqueous phase and an oil phase and the presence or absence of precipitation of magnesium salt) was visually observed. Table 1 shows the results. [Table 1] (Note) * Polyglycerin condensed ricinoleate tetraglycerin: SY Glyster CR-310 (manufactured by Sakamoto Pharmaceutical Co., Ltd.)
