METHOD FOR ISOLATING PECTIN FROM SUNFLOWER HEADS Russian patent published in 2005 - IPC

Abstract RU 2247731 C2

FIELD: vegetable raw technology.

SUBSTANCE: invention relates to a method for isolating pectin from the vegetable raw. Method for isolating pectin from sunflower heads involves their milling, denaturation of proteins by heating, hydrolysis-extraction of solid phase, separation of liquid phase and its concentrating and drying. Extraction with dimethylformamide is carried out before hydrolysis-extraction stage followed by extraction with liquid carbon dioxide under above atmosphere pressure. The second extract is separated without change of pressure followed by abrupt drop of pressure over the solid phase up to atmosphere value and feeding the solid phase to hydrolysis-extraction stage. Invention provides improving safety due to exclusion contact of toxic solvent with the end product, reducing time process of hydrolysis-extraction stage and reducing loss of pectin substances.

EFFECT: improved isolating method.
