摘要
以油茶籽压榨后的饼粕为原料,采用有机溶剂法对其残留茶油进行浸提,并对浸提工艺进行研究。通过单因素试验重点探讨溶剂、料液比、浸提温度、浸提时间等因素对油茶饼粕残油提取率的影响,并采用正交试验确定最佳浸提工艺条件。结果表明,油茶饼粕采用石油醚作为浸提溶剂,在提取温度60℃、料液比1∶8(m∶V)、提取时间7h的浸提条件下,油茶压榨饼粕残油提取率可达8.72%。
The organic solvent method was applied to extract camellia oil from oil-tea-cake and the extraction technology was studied in this paper.Effects of different solvents,ratio of material to liquid,ex-tracting temperature and extracting time on oil yield were discussed by single factor tests.The optimum extraction conditions were deter-mined by orthogonal tests.The results showed that when extracting oil-tea-cake with petroleum ether at the material to liquid ratio of 1∶ 8（m∶V）for 7hat 60℃,the best extraction effect could be ob-tained,and the extraction yield of oil was 8.72%.
