本实验采用经180尤左右煎炸时间超过13h的植物油为原料,通过静止,过滤,脱色脱臭后,以皂化温度,碱液浓度,碱与地沟油之比为实验因素,皂综合品质评分为实验指标进行单因素实验,并在单因素实验的基础上设计响应面优化实验,得出最优制皂条件为:皂化温度95.66℃,碱液浓度31.94%,地沟油与碱的比为0.53,最优的皂化度可达96.8276.
Based on the single factor experiment,this paper designs the response surface method to research the soap producing echnology by waste cooking oil,and the results show that the optimized soap producing conditions:saponification temperature of 95.66℃,alkali concentration of 31.94%,waste cooking oil/alkali ratio of 0.53,optimized saponification degree of 96.8276.
