Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the production of easily soluble combined powder, and in particular, to the easily soluble combined powder, which is characterized by spraying ethanol while maintaining the combined powder in a fluid state in a container. The present invention relates to a method for producing clothing powder.

Conventionally, when dispersing and dissolving the Gofuku powder in water or hot water, the Gofuku powder floats on the water surface and does not settle even when added to the water or hot water, and even when stirred vigorously, it only partially dissolves, resulting in a large amount of water. The problem was that the parts formed clumps and floated on the water surface or at the bottom and were not easily dispersed and dissolved.

This phenomenon occurs because the lipids contained in large amounts in the synthetic resin powder repel water. Currently, as a method to improve the disadvantage of difficulty in dispersing and dissolving in water or hot water, there is a method of increasing dispersion and solubility by using sugar solution or paste as a binder and forming it into granules using a granulator or granulator. However, the Hefei granules granulated by these methods still do not have satisfactory dispersion and solubility. Therefore, an object of the present invention is to provide a method for producing an easily soluble powder that is easily dispersed and dissolved in water or hot water.
In particular, the purpose is to produce a fine-grained, easily soluble combined powder.

As a result of our research on the production of this easily soluble glutinous powder, we focused on ethanol, which has polar lipids, and by using this ethanol as a medium to act on the lipids present in large amounts in the particles of glutinous powder, it is easy to produce. They discovered that the powder can be dispersed and dissolved in the powder, and succeeded in developing the production of easily soluble powder.

That is, the present invention involves spraying ethanol while holding a fat-impregnated powder in a fluid state in a container, and spraying ethanol containing an ethanol-soluble emulsifier while holding a fat-impregnated powder in a fluid state in a container. The present invention relates to a method for producing easily soluble fat-containing powder, which does not grow into granules but remains in the form of fine particles before treatment. The fat-containing powder used in the present invention is a fine powder dried by various drying methods such as spray drying, film drying, foam drying, vacuum drying, ultrasonic drying, high frequency drying, freeze drying, and vacuum freeze drying, and has a low lipid content. is 3% or more.

Powders with a lipid content of 3% or less are granulated into granules when treated with ethanol, and although they settle in water, their solubility is extremely poor. The present invention involves fluidizing such a fat-impregnated powder using a powder flow device such as a granulator, a granulator, or a Stephan cutter, and spraying ethanol or emulsifier-containing ethanol onto the fat-impregnated powder. Once the ethanol solution has been evenly distributed, the fat-impregnated powder is dried at 50 to 80'C until the ethanol scent disappears to form a product.

In this case, the ethanol to be sprayed is preferably 30 to 99.5% at a ratio of 50 to 400 mt per 1k9 of fat-containing powder. This is because if the amount and concentration of ethanol are below or above this level, the product powder will be difficult to dissolve and lumps will form. Also, the amount of emulsifier added is 0.5 to 5%.
is preferred, and suitable emulsifiers include lecithin, glycerin fatty acid ester, sucrose fatty acid ester, and the like. When dissolving an emulsifier in ethanol, it is desirable to leave an emulsifier that is difficult to dissolve, such as lecithin, in the ethanol for about one hour, remove insoluble matter by filtration, etc., and use the emulsifier as an ethanol solution containing the emulsifier. In addition, in the present invention, even if the fat-containing powder is treated with ethanol, the protein content is as shown in Table 1.
As shown in Table 1, almost no changes were observed, and there was no problem in dissolving the protein in ethanol.

The protein content shown in Table 11 is obtained by dissolving the treated soymilk powder and soymilk beverage powder by adding 9 times more water to 3000r'Pml.
This is the protein content of the supernatant obtained by centrifugation for 3 minutes. Next, examples of the present invention will be described.

Example 1 Put 1k9 of soy milk powder (containing 12% fat) into a powder flow device to fluidize the soy milk powder, spray 100 ml of 95.5% ethanol solution there, and spread the ethanol solution evenly over the soy milk powder. After flowing, 50-8
It was dried at 00C until the smell of ethanol disappeared.

The soy milk powder obtained in this way is smooth fine particles, the same state as before alcohol treatment, with no change in flavor or color, easily dispersed and dissolved in water with just a gentle stirring, and no lumps. It did not occur. It also dissolved well in hot water. Example 2 1k9 of soy milk powder (containing 12% fat) was placed in a powder fluidizer to flow the soy milk powder, and 60 ml of an emulsifier-containing ethanol solution containing 5 da of lecithin dissolved in 100 ml of a 95.5% ethanol solution was added thereto. After spraying and fluidizing the powder until the emulsifier-containing ethanol solution was evenly spread over the soy milk powder, it was dried at 50 to 80°C until the ethanol scent disappeared.

The soybean milk powder thus obtained was a smooth, fine powder with no change in flavor or color, and was easily dispersed and dissolved in water or hot water by gentle stirring, and no lumps were formed. Examples 3 to 8 Whole milk powder (contains 25% fat), soy milk drink powder (30% fat)
, containing 20% carbohydrates) and cocoa powder (containing 22% fat) were added to 100 ml of 95.5% ethanol and 60 ml of ethanol containing an emulsifier in the same manner as in Examples 1 and 2.
1.

The obtained whole milk powder, soy milk beverage powder, and cocoa powder are all smooth, fine powders with no change in flavor or color, and can be easily dispersed and dissolved in water or hot water by just stirring lightly, and there are no lumps. No such symptoms occurred. Next, a comparative example is given for reference. Comparative Example 1 Put 1k9 of soy milk powder (containing 12% fat) into a powder flow device to fluidize the soy milk powder, spray 100 wLL of water there, and fluidize the powder until the water is evenly distributed over the soy milk powder. It was dried at 50-80°C.

The soy milk powder obtained in this way is granulated into granules, and even when stirred in water or hot water, only a portion dissolves, but the majority settles and floats on the bottom, making it extremely difficult to dissolve. It became difficult. Comparative Example 2 1 kg of skim milk powder (containing 1% fat) was placed in a powder flow device to flow the skim milk powder, and 100 mL of 95.5% ethanol solution was sprayed there, and the powder was poured until the ethanol solution was evenly spread over the skim milk powder. After fluidizing, 50~
It was dried at 80°C.

The skim milk powder obtained in this way is granulated into grains, and even when stirred in water or hot water, only a portion dissolves, but the majority settles and floats on the bottom, making it extremely difficult to dissolve. It became difficult. As is clear from the above Examples and Comparative Examples, according to the present invention, easily soluble fat-containing powder that can be easily dispersed and dissolved in water or hot water from fat-containing powder, especially fat-containing powder with fine particles. There is an advantage that you can get
