中文摘要: 以离心沉淀率为检测指标,研究复配酶制备燕麦浊汁的酶解工艺。采用单因素试验,考察复配酶的添加量、酶解温度、酶解pH值、酶解时间4个因素对燕麦浊汁稳定性的影响,并通过正交试验确定燕麦浊汁酶解的最佳工艺参数:复配酶添加量0.3%,酶解pH 6.4,酶解温度55℃,酶解时间80 min。在此工艺条件下,燕麦浊汁离心沉淀率为17.6%。
Abstract:Efficacy of turbid oat juice hydrolysis using a mixture of enzymes was assessed by determining centrifugal sedimentation rates.Using single factor and orthogonal test methods,the effects of enzyme mixture concentration,enzymolysis temperature,enzymolysis pH,and enzymolysis time on turbid oat juice stability were analyzed.The optimum processing parameters were 0.3% enzyme mixture,pH 6.4,55℃,for 80 min.Under these conditions,the centrifugal sedimentation rate of turbid oat juice was 17.6%.
