| 摘 要： | 研究了混合溶剂浸提富含黄酮、VE的麦胚油。对正己烷、正己烷/乙酸乙酯、正己烷/正丁醇、正己烷/丙酮、甲醇/丙酮、异丙醇/1,2-二氯乙烷6种浸出溶剂进行筛选,发现正己烷/丙酮浸出效果较理想。兼顾提油效率、所提麦胚油的VE含量和黄酮含量,采用单因素实验和正交实验得出正己烷/丙酮浸出麦胚油的理想工艺条件为:浸出温度45℃,浸出溶剂滴速5.5 mL/min(原料100g),浸出时间45 min。该条件下,脱脂麦胚残油率0.354%,麦胚油VE含量3.794 9 g/kg,黄酮含量10.29 g/kg。

| Abstract: | Technical conditions of extracting vitamin E and flavonoids rich oil from wheat germ were investigated. Six different extracting solvents of n-hexane, mixed solvent of n-hexane and ethyl acetate, mixed solvent of n-hexane and butanol, mixed solvent of n-hexane and acetone, mixed solvent of methanol and acetone, mixed solvent of isopropanol and 1,2-dichloroethane were selected to investigate the extracting effect, and the mixed solvent of n-hexane and acetone was the ideal solvent. The process parameters were optimized for preparing wheat germ oil with maximum retention of the functional substances (V_E, flavonoids). The optimal extraction conditions were established through single factor experiments and orthogonal experiments as follows: extracting temperature 45 ℃, dropping rate of solvent 5.5 mL/min for 100 g wheat germ, extracting time 45 min. Under these conditions, the residual oil in wheat germ meal was 0.354%, and the content of V_E and flavonoids in the oil were 3.794 9 g/kg and 10.29 g/kg, respectively. |
