西番莲果皮中果胶的复合酶法提取工艺研究
Research on the compound enzymatic extraction process of pectin from passionflower peel
摘要
Abstract
Passionflower peel was used as raw materials in the reseach.With enzyme solution pH,hydrolysis time,hydrolysis temperature,enzyme concentration and ratio of liquid to material as single factors,the effects of four kinds of enzyme (cellulase,hemieellulase and lignin enzymes,amylase) on pectin extraction from the passionflower peel were studied.And the enzyme combination consists cellulose,hemicellulase and lignin enzymes were determined.Through L9 (34) orthogonal experiment and response surface test,the enzymatic hydrolysis and enzyme concentration were optimized.the optimal enzymatic hydrolysis conditions were as follows:cellulose enzymes 0.8 g/100 g,hemicellulase 1.2 g/100 g,and lignin 0.2 g/100 g,ratio of liquid to material(mL/g)6∶ 1,pH value 4,extraction lasts for 3.5 h under the temperature of 40 ℃,the pectin gain rate can reach 2.63％ ±0.021％.关键词
