摘　　要：天然维生素E具有较高的生物活性和抗氧化性,大量富集于油脂脱臭馏出物中。本研究采用分子蒸馏技术对大豆油脱臭馏出物(SODD)中的天然维生素E进行提取,利用高效液相色谱方法检测VE含量。通过单因素实验和正交实验得到最佳工艺条件为:蒸馏温度210℃,刮膜转速450 r/min,流量为3.7 g/min,压强为10 Pa,此条件下可制备得到质量分数达40%的天然维生素E产品。Natural vitamin E(VE)has high biological activity and antioxidant activity which is widely present in oil deodorized distillates.In this study,the natural vitamin E in soybean oil deodorized distillate(SODD)was extracted by molecular distillation technique,and the VE content was determined by high performance liquid chromatography.The optimum conditions were obtained by single factor test and orthogonal test as follows:distillation temperature 210℃,scraping speed 450 r/min,flow rate 3.7 g/min,pressure 10 Pa.under these conditions,natural vitamin E productswith purity up to 40%could be prepared.This study can provide reference for the industrial production of natural vitamin E with molecular distillation technology.
