摘要
Abstract
Response surface analysis was used to optimize the enzymatic conditions of nature milk flavor essence.The cream was used as raw material,palatase 20,000L was selected as the lipase used for enzymolysis reaction and the sensory evaluation as the major index.According to the single factor test and analysis method a 4 × 3 factorial central composite design was employed to optimize hydrolysis of cream for polynomial models of multiple regression analysis,the factors contained substrate concentration,pH,hydrolysis temperature and hydrolysis time.Results showed that the optimum conditions were hydrolysis temperature 61.0 ℃,hydrolysis time 3.60 h,pH 7.92,and substrate concentration 36.0%,the enzymatic product had a rich and pleasant butter flavor.关键词
