Optimization of enrichment and purification technology of α-linolenic acid in Eucommia seed oil by the urea adduction fractionation method
摘要
Abstract
Quadratic rotation-orthogonal combination design was applied to optimize the enrichment and purification techniques of α-linolenic acid in Eucommia ulmoides seed oil by the method of urea adduction fractionation.By taking α-linolenic acid purity as the investigation index,the effects of four process parameters named ratio of urea to fatty acid,ratio of 95％ ethanol to fatty acid,inclusion temperature and inclusion time on the enrichment results were investigated and the two times multiple regression equation model of α-linolenic acid purity was established based on the single factor experiments.The results showed that the optimum levels of the four parameters were as follows:3∶1,9∶1,-9.0℃ and 17.0h,respectively.Under the optimum enrichment conditions,the purity of α-linolenic acid was up to 82.63％.Urea adduction fractionation was an effective method for the enrichment of α-linolenic acid in Eucommia ulmoides seed oil.关键词
