响应面法提高巨峰葡萄榨汁率的研究

摘要

通过响应面法,研究果胶酶酶用量、酶解时间和酶解温度对巨峰葡萄榨汁率的影响,并对其工艺进行条件优化.结果表明,最佳工艺条件为酶用量0.044 ml/kg,酶解时间97.5 min,酶解温度57 ℃.在此条件下,榨汁率达87.35%.%The effects of pectinase enzyme usage, reaction time and temperature on the extraction yield of juice from Kyoho were investigated based on response surface methodology. Results showed that the optimum condition was as follows: usage of 0.044 ml/kg, reaction time of 97.5 min and temperature of 57 ℃. Under this condition, juice yield reached 87.35％.
