METHOD FOR PRODUCTION OF PECTIN PREPARATION FROM CITRUS REFUSES Russian patent published in 2005 - IPC

FIELD: technology for production of pectin extract from vegetable raw materials.

SUBSTANCE: claimed method includes hydrolysis-extraction and liquid phase separation wherein citrus refuses are forehead subsequently extracted with dimethyl formamide and mixture of liquid acetylene and carbon dioxide in mass ratio from 3:7 to 7:3. Hydrolysis-extraction is subsequently carried out in forward flow and backflow with intermediate pressing. As extractants in backflow process water and in forward flow process extract separated after backflow stage are used, respectively.

EFFECT: decreased pectin losses without deterioration of organoleptic characteristics.
