摘　　要：文章采用6号白电油为有机溶剂,以蚕蛹油提取率为评价标准,对干蚕蛹油脂提取工艺进行研究探讨。首先对单因素如浴比、提取温度、提取时间和翻滚次数因素分析,选出较佳范围值;再采用正交试验和直观分析法,得出最佳工艺条件;最后,利用石油醚对较佳工艺条件下提取试样进行二次蛹油提取,验证6号白电油提取效果。结果表明:最佳提取工艺参数为浴比(固液比) 1︰3、提取温度60℃、提取时间3 h、翻滚次数60次。此条件下,蚕蛹油的最大提取率为21. 87%,单因素对提取率的影响顺序为浴比>提取温度>翻滚次数>提取时间。同时,石油醚对最佳工艺条件下残渣进行二次提取,表明6号白电油对干蚕蛹油脂提取效率为87. 62%。In this paper,No.6 white mineral oil was used as organic solvent,and the extraction rate of silkworm pupa oil was used as evaluation standard to explore the oil extraction process from dried silkworm pupae.Firstly,the factors such as bath ratio,extraction temperature and time,and number of rolling were analyzed,and the better range values were selected.Secondly,orthogonal test and visual analysis were applied to obtain the best process conditions.Finally,the extraction of the sample with the petroleum ether under the optimum conditions was carried out to verify the extraction effect of the white mineral oil.The results showed that the optimum extraction parameters were as follows:bath ratio(solid to liquid ratio)1︰ 3,extraction temperature 60℃,extraction time 3h,and number of times of rolling 60 times.Under such conditions,the maximum extraction rate of silkworm pupa oil was 21.87%.The influence order of single influence factors on extraction rate is as follows:bath ratio,followed by extraction temperature,number of times of rolling and extraction time.At the same time,the secondary extraction of the residue with petroleum ether was conducted under the optimum technological conditions.The result showed that the extraction efficiency with No.6 white mineral oil from the dried silkworm chrysalis oil is 87.62%.
