METHOD TO PRODUCE PECTIN FROM PLANT RAW MATERIALS Russian patent published in 2017 - IPC C08B37/06 

FIELD: food industry.

SUBSTANCE: invention relates to food, pharmaceutical and biochemical industries. Method of pectin production includes extraction of pectin-containing pomaces by solution of food or mineral acid with pH of 0.8-3.2 and hydraulic module of 1:(15-45) for 1-6 hours at temperature of 70-95°C, filtration of produced extract, its treatment. Then extract is concentrated on a cascade of ion-exchange and adsorption columns, ultrafiltration and diafiltration plants with polymer membranes with cut off at 20-100 kDa. Produced pectin solution is dried at temperature of 45-95°C to produce pectin in drying belt vacuum deviced with subsequent grinding of pectin or devices of spray type. Besides, removal of ballast substances in ion exchange and adsorption processes is carried out on cation exchange resins AMBERLITE® FPC23 H, anion exchange resins AMBERLITE® FPA90 Cl and adsorption resins AMBERLITE® FPX66.

EFFECT: invention makes it possible to increase yield of pectin, extent of purity and to produce pectin with specified molecular mass.
