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 of mixture, separation of a liquid phase and isolation of the end product from its. Before mixing sunflower heads and citrus husks are extracted with ethyl acetate and liquid carbon dioxide separately and successively under the above atmosphere pressure. The second extract is separated without pressure change followed by dropping pressure over a solid phase up to atmosphere value and feeding a solid phase to hydrolysis-extraction. Invention provides enhancing quality of the end product due to elimination of undesirable taste and odor and without deterioration of its technological properties and without reducing the specific yield of pectin.

EFFECT: improved preparing method.
