METHOD FOR PREPARING PECTIN Russian patent published in 2005 - IPC

FIELD: vegetable raw technology.

SUBSTANCE: invention relates to a method for isolating pectin from vegetable raw. Method for preparing pectin involves milling and mixing sunflower heads and citrus husks, hydrolysis-extraction, separation of a liquid phase and isolation of the end product from its. Sunflower heads and citrus husks are extracted with dimethylformamide and mixture of liquid acetylene and carbon dioxide before mixing separately and successively taken in the mass ratio acetylene : carbon dioxide from 3:7 to 7:3 under the above atmosphere pressure and corresponding extracts are separated. After separation of the second extract pressure is dropped abruptly up to atmosphere value, solid phases of sunflower heads and citrus husks are mixed and fed to hydrolysis-extraction. Invention provides enhancing quality of the end product due to elimination of undesirable taste and odor being without deterioration of its technological properties and without reducing the specific yield of pectin.

EFFECT: improved preparing method.
