摘要

FIELD: food industry. ^ SUBSTANCE: invention relates to a method for producing pectin extract. Method involves dosing apple pulps and their mixing with cherry plum puree taken in the ratio 1:4 followed by addition of citric and succinic acids taken in the ratio 3:2 and in the amount 0.01-0.02% of the raw mass. Then method involves extraction in combination with acid-thermal hydrolysis of raw at hydromodulus 1:6, at temperature 80-90°C for 120-140 min at pH = 2-2.5. Prepared extract is separated and filtered off. Invention provides increasing yield of pectin substances and enhancing quality of pectin. ^ EFFECT: improved preparing method of pectin. ^ 3 tbl, 4 ex
