摘要
采用α-淀粉酶和糖化酶协同水解作用生产大麦保健茶,并且对酶解参数进行研究。试验以大麦汁中还原糖含量作为考察指标,选取双酶比例,酶促反应温度和反应时间3个参数进行研究。得到最优的试验条件为α-淀粉酶为4 U/g,糖化酶为6 U/g,酶促反应温度为40℃,时间为40 min。双酶水解体系具有反应温度低、时间短、酶促反应效率高的优点。
Barley health beverage was produced by synergistic hydrolysis with α-amylase and glucoamylase,and the parameters were determined through orthogonal test.Using reducing sugar content as index,the ratio of two enzyme,reaction temperature and time was optimized.The results indicated that the optimum processing parameters were α-amylase 4 U/g,glucoamylase 6 U/g,temperature 40 ℃,time 40 min.The advantages of synergistic hydrolysis with α-amylase and glucoamylase were efficient with lower temperature and shorter time.
