METHOD FOR EXTRACTION OF PECTIN SUBSTANCES IN NATIVE STATE FROM ROSEHIP FRUIT SHELLS Russian patent published in 2013 - IPC A23L1/524 

FIELD: food industry.

SUBSTANCE: invention relates to food industry. The method envisages preliminarily soaking of milled rosehip fruit shells with water during an hour at a temperature of 20°C at water duty equal to 6. Then one performs extraction under the action of ultrasound at 22 kHz, at power equal to 20 W and energy density equal to 0.2 W/cm³ during 10 minutes. Then the produced mixture is subjected to fermentative hydrolysis using Pectofoetidin P10x enzyme preparation in a dosage equal to 0.03% of the fruit shells weight at a temperature of 40°C in accordance with the optimum of the preparation pectinesterase activity during 1 hour. Then the extract is separated from the solid phase.

EFFECT: invention allows to increase the target product yield, enhance its complexing ability, reduce consumption of energy and material resources.
