Optimization of Aqueous Enzymatic Extraction of Polysaccharides from Rapeseed Meal by Response Surface Methodology
摘要
Abstract
The aqueous enzymatic extraction of polysaccharides from rapeseed meal was optimized by response surface methodology. One-factor-at-a-time method was employed to investigate the effects of five operating parameters on polysaccharide yield. The optimum ratio of water to material was 25:1 (mL/g). Further, a quadratic polynomial regression model describing polysaccharide yield as a function of enzyme dosage, pH, temperature and extraction time was developed using the SAS software based on a Box-Behnken experimental design. The results of response surface analysis showed that the optimal extraction conditions were extraction at 62℃and pH 6.7 for 79 min with an enzyme dosage of 256 U/g, resulting in a polysaccharide yield as high as 9.01%.关键词
