METHOD FOR EXTRACTION OF PROTEIN, STARCH AND FIBER FROM BUCKWHEAT Russian patent published in 2022 - IPC C08B30/04 A23J1/12 

FIELD: food industry.

SUBSTANCE: invention relates to the food industry, in particular to a method for the extraction of protein, starch, and fibers from buckwheat groats or flour. The method includes a) obtaining an aqueous suspension from buckwheat flour or from buckwheat groats at a temperature of less than 50°C, with a pH value from 7 to 9; b) fractionating the aqueous suspension by density to obtain a light fraction containing proteins, soluble carbohydrates, and salts and a heavy fraction containing starch and fibers; c) treating the light fraction to isolate proteins; d) treating the heavy fraction to separate starch from fibers. In this case, the stage a) of obtaining the aqueous suspension provides for a stage of adding water to buckwheat flour or to buckwheat groats in a ratio of 4:1 (wt./wt.) at a temperature in the range from a room temperature to 50°C.

EFFECT: method allows for isolation of components without the use of organic solvents and organic reagents, i.e., by the “clean label” principle.
