METHOD FOR PRODUCTION OF PECTIN EXTRACT FROM SOYA BEAN SHELLS Russian patent published in 2015 - IPC A23L1/524 

FIELD: food industry.

SUBSTANCE: method envisages soya bean fruit envelope drying and milling into 1-4 mm particles and removal of impurities. Then one proceeds with hydrolytic extraction with an organic acid during 120 min and liquid phase separation once the hydrolytic extraction process is over. Prior to drying, the raw material is washed. Hydrolytic extraction is with a 0.3 solution of amber acid at a temperature of 80-85°C, duty of water being 1:10.

EFFECT: invention allows to solve the task of processing secondary raw material resources of soya seeds production and preservation of pectin physicochemical properties, to impart consumer properties to the target product through application of amber acid as a hydrolysing agent ensure the maximum yield of pectin substances.
