【摘要】 对油茶籽油高提取率提取工艺展开研究，以油茶籽饼为原料，采用超声波辅助溶剂浸提茶油。通过单因素试验分析了溶剂种类、料液比、浸出温度、浸提时间对油茶籽饼残油率的影响；在此基础上以温度、时间、料液比为影响因素，以残油率作为指标，设计正交试验来优化油茶籽饼残油的提取工艺条件。结果表明，最佳提取工艺条件为采用乙醇+环己烷（体积比为3∶1）作为提取溶剂，浸出温度50℃，浸出时间60 min，料液比1∶6。可以将残油率降低至0.53%。更多还原

【Abstract】 This paper studied the high extraction rate of camellia seed oil,and extracts camellia oil with camellia seed cake.The influence of solvent type,liquid ratio,immersion temperature and extraction time on the oil residual rate were analyzed.On this basis,taking temperature,time and solid-liquid ratio as influencing factors and residual oil rate as index,orthogonal experiment was designed to optimize the extraction conditions of residual oil from Camellia oleifera seed cake. The results showed that the best extraction process was ethanol + cyclohexane(volume ratio of 3∶1) as the extraction solvent,immersion temperature of 50 ℃ and immersion time of 60 min,and liquid ratio of 1∶6. The residual oil rate could be reduced to 0.53%.更多还原
