以猪脂肪、氢氧化钠、氯化钙为原料，在实验室条件下探索脂肪酸钙的加工工艺和加工过程。利用正交试验设计(L1645)对脂肪酸钙的加工工艺系数进行反复筛选，探索脂肪酸钙的最佳加工工艺参数。结果表明，脂肪酸钙的最佳加工工艺参数为氢氧化钠用量占脂肪重的27%、氯化钙用量占脂肪重的25%、皂化反应时间为5 h、复分解温度为90 ℃、用水量为脂肪的4倍。

This study used pig fat， sodium hydroxide， and calcium chloride as the main material. The parameters of processing technique of calcium fatty acids were determined and the optimal process condition was recommended by the orthogonal design L1645. The results show that the processing technology parameter of fatty acid calcium in experiment condition were: dosage of sodium hydroxide accounted for 27% of fat mass， dosage of calcium chloride accounted for 25% of fat mass， saponification reaction time of 5 h， double replacement reaction temperature was 90 ℃， the usage amount of water was 4 times of fat mass.
