METHOD OF PREPARING FRUIT OR VEGETABLE POMACE FOR THE PRODUCTION OF SORBENTS Russian patent published in 2018 - IPC A23L33/10 

FIELD: food industry.

SUBSTANCE: invention relates to the preparation of pomace from fruits or vegetables for the production of a sorbent used in the production of food products in the formulation of which no dyes are used, and also in the pharmaceutical industry. Method is characterized in that during an hour after the juicing, oxidation of polyphenols in the pomace is inhibited by spraying them with an aqueous solution of sodium chloride with a mass fraction of 0.15–0.50 % of dry matter. In this case, solution and pomace are used in a ratio of 1:1 with continuous stirring for 10–15 minutes and pressed. Then pomace is treated with a solution of ascorbic acid with a concentration of 0.09–0.20 % for 10–15 minutes with continuous stirring, dried at a temperature of not higher than 50 °C to a humidity of 7–8 % and ground to a powder.

EFFECT: invention ensures the production of a sorbent retaining its sorption properties for a long time and not changing its color.
