FIELD: vegetable raw technology.

SUBSTANCE: invention relates to a method for preparing pectin from vegetable raw. Method for preparing pectin involves milling and mixing sunflower heads and citrus husks, hydrolysis-extraction of mixture, separation of a liquid phase and isolation of the end product from its. Sunflower heads and citrus husks are extracted with dimethylformamide and liquid acetylene before mixing separately and successively under the above atmosphere pressure and corresponding extracts are separated. After separation of the second extract pressure is dropped abruptly to atmosphere value and 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.
