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

FIELD: technology of natural substances.

SUBSTANCE: invention describes a method for preparing the pectin preparation involving milling and mixing sunflower heads and citrus husks taken in the ratio by mass from 1:9 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 acetone and mixture of liquid acetylene and carbon dioxide taken in the ratio by mass from 3:7 to 7:3. Then the prepared solid phase is mixed and subjected for hydrolysis-extraction successively in direct flow and in countercurrent with intermediate squeezing out. Water is used as an extractant at stage of countercurrent carrying out the process, and extract separated after countercurrent stage is used at stage of direct flow with addition of acid. Method 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.
