摘要

为提高香榧(Torreya grandis)油提取率和了解香榧油具体成分,以香榧为试验材料,采用单因素试验,研究料液比、超声功率和超声时间对香榧油提取率的影响;采用响应面法优化香榧油提取工艺,加入不同表面活性剂和助表面活性剂,确定香榧油微乳制备工艺.结果表明,在超声时间25 min、超声功率352 W和料液比1∶15 g/mL的条件下,香榧油提取率为48.92％.GC-MS分析结果表明,香榧油以棕榈油酸、硬脂酸、油酸、亚油酸、二十碳二烯酸和神经酸为主.香榧油微乳的制备工艺为以香榧油为油相、无水乙醇为助表面活性剂、PEG-40和Tween-80为表面活性剂,无水乙醇、PEG-40和Tween-80的质量比为3∶1∶2.

Abstract

In order to improve extraction rate of Torreya grandis oil and understand specific components of T. grandis oil, taking T. grandis as experimental materials, single factor experiment was designed to study ef-fects of solid to liquid ratio, ultrasonic power and ultrasonic time on extraction rate of T. grandis oil. Response surface method was used to optimize extraction process of T. grandis oil. Preparation process of microemulsion of T. grandis oil was determined by adding different surfactants and co-surfactants. Results showed that extrac-tion rate of T. grandis oil was 48.92％under conditions of ultrasonic time of 25 min, ultrasonic power of 352 W and solid to liquid ratio of 1∶15 g/mL. Results of GC-MS analysis showed that palmitoleic acid, stearic acid, oleic acid, linoleic acid, eicosadienoic acid and nervonic acid were dominant in T. grandis oil. Preparation pro-cess of microemulsion of T. grandis oil was based on T. grandis oil as oil phase, anhydrous ethanol as co-surfac-tant, PEG-40 and Tween-80 as surfactants, and mass ratio of anhydrous ethanol, PEG-40 and Tween-80 was 3∶1∶2.
