摘要
Abstract
The extraction of olive leaves was hydrolyzed by hydrochloric acid and p-glycosidase respectively to prepare hydroxytyrosol.The orthogonal design was adopted to find out the optimal processing conditions of both methods.Results showed that the optimal hydrochloric hydrolysis conditions were as follows; hydrochloric acid concentratio 0.2mol/L, ratio of solvent volume to extract of olive leaves (mL/mg) 50:1 ,and hydrolyzing for 6h at 80℃.The optimal enzymatic hydrolysis conditions were as follows: pH 7.0, enzyme concentration 25U/mg,and hydrolyzing for 5h at 50℃.ln view of production cost and the yield of hydroxytyrosol, the method of hydrochloric acid was better than the method of enzymatic hydrolysis.关键词
