Easily dispersible granules of soybean protein and methods for preparing the same

摘要

An easily dispersible granule of soybean protein comprises powdery soybean protein whose surface is coated with a carbohydrate, which is not readily digestible, wherein the carbohydrate is present in an amount of at least 5 parts by weight per 100 parts by weight of the powdery soybean protein. A method for preparing such an easily dispersible granule of soybean protein in which powdery soybean protein is granulated while the powder is sprayed with an aqueous solution containing a carbohydrate which is not readily digestible and which is characterized by using at least 5 parts by weight of the hardly digestible carbohydrate per 100 parts by weight of the powdery soybean protein is also disclosed. An Alternative method involves spraying a dry mix of soybean protein and not readily digestible carbohydrate with lecithin in water, and removing the water from the resultant lecithin-coated mix.
