摘要
本文研究了超声波处理后,用硫酸铝沉淀法从佛手瓜中提取果胶的新方法。正交试验结果表明,超声波处理的最佳条件为超声波处理时间 40 min,功率为 60 %,温度 65℃。此条件下的果胶产率为 3.48%。而普通盐析法的果胶产率为 0.58%。
In this essay, we extract pectin from chayote with ultrasonic wave and salting-out way. By orthogonal design experiment, the best condition is obtained, that is, ultrasonic wave time 40 min, power 60%, and temperature 65℃ , and the rate of production is 3.48% on this condition.
