METHOD FOR PRODUCING CROSS-LINKED STARCH Russian patent published in 2022 - IPC C08B31/18 C08B30/12 A23L29/219 A23L5/20 

FIELD: food industry.

SUBSTANCE: invention relates to a method for producing cross-linked starch for long-term storage conditions when it is used as an ingredient in food products and using food products containing the specified cross-linked starch. The method for producing cross-linked starch includes stages of a) obtaining a suspension containing native granular starch obtained from starch-containing raw materials, b) alkalizing the suspension by adding ammonia or by adding one or more compounds capable of releasing or forming ammonia in the suspension, where ammonia added to the suspension or ammonia released or formed in the suspension is present in the amount relatively to the starch suspension of 0.05-3.0% wt./wt. of the starch dry matter (DM), c) bringing the pH of the suspension to a value from 7 to 10, d) adding at least one oxidizer, which is a source of active chlorine, to the suspension for reaction with the specified ammonia, where the oxidizer is added in the amount of 0.1-4% wt./wt. of starch dry matter (DM), e) adding at least one organic acid or bisulfite to the suspension in order to remove any residual oxidant, foreign taste and undesirable odor, and f) adding at least one antioxidant to the suspension in order to stabilize the achieved starch cross-linking during long-term storage in a warehouse.

EFFECT: providing a method for obtaining cross-linked starch that retains its degree of cross-linking when stored under normal conditions in warehouses and in vehicles.
