澄清型香蕉汁的制备中,果胶酶应用的工艺条件对产品的品质有很大影响。分别考察了果胶酶的添加量、温度、反应时间等因素对香蕉汁澄清度的影响,并通过正交试验发现,反应温度55℃,反应时间为150 min,果胶酶质量浓度为0.09 g/L,果汁的透光率最大为76.74%。
The effect on banana juice clarification is studied by using pectinase.Separ-ately is studied the influence factors of banana juice clarification such as pectinase add volume,temperature and so on.The results indicate that the juice is treated at 55 ℃ for 150 min,in the condition of 0.04% pectinase usage,the transmittance of juice is 76.74%.
