METHOD FOR PRODUCING PECTIN PREPARATION Russian patent published in 2005 - IPC

FIELD: technology of natural substances.

SUBSTANCE: invention describes a method for producing pectin preparation that involves milling and mixing sunflower heads and citrus husks in the ratio by mass from 9:1 to 9:1, hydrolysis-extraction of mixture, separation of liquid phase and isolation of the end product from its. Before mixing the raw is extracted successively with ethyl acetate and mixture of liquid acetylene and carbon dioxide taken in the ratio by mass from 3:7 to 7:3 under above atmosphere pressure. After separation of the second extract pressured is dropped to atmosphere value and hydrolysis-extraction is carried out by successive carrying out the process in direct flow and in countercurrent with intermediate squeezing out and using water as an extractant at stage of countercurrent carrying out the process and using extract separated after direct flow stage with addition of acid at the stage of direct flow. Method provides enhancing quality of the end product due to elimination of undesirable taste and odor being without deterioration of technological properties and without reducing the specific yield of pectin.

EFFECT: improved producing method.
