为降低酸值,将烧碱与纯碱分别用于高酸值压榨花生油的脱酸过程,通过对比研究了不同条件对两种方法脱酸的影响,并确定纯碱脱酸的最佳条件为:碱液浓度20%~25%,加碱量小于理论值的1.5倍,温度20~30℃,搅拌时间20~25 min。综合比较来看,纯碱脱酸效果要优于烧碱。
為降低痠值,將燒堿與純堿分彆用于高痠值壓榨花生油的脫痠過程,通過對比研究瞭不同條件對兩種方法脫痠的影響,併確定純堿脫痠的最佳條件為:堿液濃度20%~25%,加堿量小于理論值的1.5倍,溫度20~30℃,攪拌時間20~25 min。綜閤比較來看,純堿脫痠效果要優于燒堿。

The caustic soda and soda were respectively used to reduce the acid value of peanut oil with high acid value. The effects of different conditions on the two deacidification process were comparatively studied and the optimum deacidificating conditions using soda were:concentration 20%~25%,1.5 times less than the theoretical value of the alkali,temperature 20~30℃,the stirring time 20~25 min. Compared comprehensively,the deacidification effect using soda is superior to the caustic soda.
