Study on extraction of cod oil by enzymatic hydrolysis
摘要
Abstract
Co d oil was extracted by papain hydrolysis.The technology was optimized by single factors and response surface tests according to the extraction rate.The technology was compared with tradition-al dilute alkaline hydrolysis in the aspects of cod oil extraction rate and quality.The result showed that the optimum condition of enzymatic technology was as follows:ratio of solid to liquid 1 ∶1 .5,pH 6.5, the quantity of enzyme 3 270 U /g,temperature 50 ℃and enzymolysis time 2 h.The extraction rate of the optimal technology could reach 93.44% and the obtained fish oil had good quality with acid value 5.49 mg /g,iodine value 148.31 g /100 g and peroxide value 7.49 meq /kg.The extraction rate and quality of cod oil extracted by the enzymatic hydrolysis was prior to that extracted by the diluted alkaline hydrolysis method.关键词
