METHOD FOR PRODUCING MODIFIED STARCH Russian patent published in 2022 - IPC C08B30/02 C08B30/14 

FIELD: foodstuffs.

SUBSTANCE: invention relates to the food industry and is intended for producing modified starch. The method for producing modified starch consists in gelatinising a starch suspension forming a gel, freezing and defrosting said gel. Potato starch, and/or corn starch, and/or tapioca starch, and/or wheat starch, and/or rye starch, and/or barley starch, and/or triticale starch, and/or rice starch, and/or sorghum starch, and/or pea starch are used for modification. 1 to 30% water and starch paste is prepared from starch, slowly adding starch suspension to boiling water and simultaneously mixing thoroughly. The water and starch paste is then cooled to a temperature of 20 to 25°C, frozen at a temperature of -5 to -70°C, defrosted at a temperature of +20 to +30°C, dehydrated and dried at a temperature of no more than +60°C, followed by crushing using a hammer crusher to particles of 0.1 to 1.0 mm in size, sieving through a sieve with holes no bigger than 1.0 mm, and removing metallomagnetic impurities.

EFFECT: execution of the invention allows for production of cryogenically modified resistant starch by a highly efficient and resource-saving method.
