摘　　要：以出油率、酸值及过氧化值为评价指标,通过正交试验法,比较了压榨法与热浸提法对普洱茶籽油提取的影响,结果表明热浸提法提取效果较压榨法好。压榨法的最佳条件为:含水量7%,入榨温度110℃,粒度4 mm;热浸提的最佳提取溶剂是正己烷、提取时间4 h、料液比1∶8,温度60℃。The differences between expression and heat extraction in the extraction of puer tea seed oil were studied by orthogonal experiment with oil yield,acid value and peroxide value as the evaluation index.The results showed that heat extraction technology is better than expression.The optimum conditions of expression were moisture content 7%,pressing temperature 110 ℃ and the granularity of puer tea seed 4mm.The optimum conditions of heat extraction is hexane as the solvent,solid-liquid ratio 1∶8,extraction time 4 hours and temperature 60 ℃.
