Description

TECHNICAL FIELD The present invention relates to a water dispersibility improver for soy protein-containing powder.

Soybean protein-containing powders are widely used in processed meat and processed marine products because of their properties such as heat coagulability, water retention and oil retention. In addition, soy protein-containing powder is dispersed in water and drunk for the purpose of promoting muscle synthesis and supplying protein for cosmetic effects. However, the soy protein-containing powder has poor dispersibility in water, and when added to water, the wet part forms a film, which inhibits the penetration of water into the interior, resulting in "mamako" (or " There is a problem that it forms lumps called "lumps" and does not disperse uniformly.

As a method for improving the water dispersibility of the soy protein-containing powder, for example, water, glycerin fatty acid ester, sorbitan fatty acid ester, propylene glycol fatty acid ester, and/or sugar are added to the raw soy protein powder when performing fluidized bed treatment. A method for producing powdered soybean protein, which comprises spraying a water-containing liquid containing an ester as a surfactant (Patent Document 1). Soybean protein powder containing polyglycerin fatty acid ester composed of glycerin (Patent Document 2), powdered soybean protein obtained by adhering polyglycerin fatty acid ester to soybean protein having a water-soluble nitrogen index (NSI) of 50 to 85 White (Patent Document 3) and the like have been proposed.

However, since the formation of "mamako" may not be sufficiently suppressed even by the above methods, a new method capable of improving the water dispersibility of soy protein-containing powder has been desired.
