摘　　要：为了探究南瓜籽油正戊烷提取的可行性,以南瓜籽为原料,通过单因素和响应面设计对南瓜籽油提取工艺进行了优化。试验结果表明:浸出温度为30℃、浸提次数为5次、浸出时间为30min、液料比值为12,南瓜籽的出油率可达50.67%,提取率为98.8%。此工艺条件提取南瓜籽油的酸值和过氧化值符合食用油国家质量标准,表明正戊烷提取南瓜籽油是可行的。The feasibility to extract pumpkin seeds oil by n-pentane was studied.The extraction technique was optimized by single factor experiment and respond surface methodology.The results showed that the optimal extraction conditions were,ratio of liquid-solid was 12 at 30 ℃ for 30min,extraction for 5 times,the oil yield was 50.67% and the extraction rate can reach 98.8%.The acid value and peroxide value of the oil were lower than the corresponding value of the national quality standards.So extraction of pumpkin seed oil by n-pentane as new solvent was workable.
