【摘要】：以林蛙卵为原料,以无水乙醇为提取剂,研究微波法对林蛙卵油提取率的影响。在单因素试验的基础上,进行响应面优化试验,研究料液比、浸泡时间、微波功率对林蛙卵油提取的影响。结果表明,提取最佳工艺条件为料液比1∶9.82(g/mL)、浸泡时间3.33 h、微波时间30 min、微波功率600 W;林蛙卵油的提取率可达到(20±0.67)%。与其他林蛙卵油提取方法比较,微波法辅助提取林蛙卵油具有得率高的优点。对得到的林蛙卵油采用气相色谱-质谱分析检测出27种脂肪酸,不饱和脂肪酸质量分数54.98%,其中以亚油酸、二十碳二烯酸、二十碳三烯酸、二十碳四烯酸、亚麻酸、棕榈反油酸、二十二碳五烯酸含量较高。
[Abstract]:The effect of microwave method on the extraction rate of Rana frog egg oil was studied by using anhydrous ethanol as extractant and Rana frog eggs as raw material. On the basis of single factor test, the response surface optimization test was carried out to study the effects of the ratio of material to liquid, soaking time and microwave power on the extraction of Rana chensinensis egg oil. The results showed that the optimum extraction conditions were as follows: the ratio of material to liquid was 1: 9.82 g / mL, soaking time was 3.33 h, microwave time was 30 min, microwave power was 600 W, and the extraction rate of Rana frog egg oil could reach 20 卤0.67. Compared with other extraction methods, microwave assisted extraction has the advantage of high yield. Twenty-seven kinds of fatty acids were detected by gas chromatography-mass spectrometry. The unsaturated fatty acid content was 54.98. Among them, linoleic acid, eicosodienoic acid, eicosylenoic acid, linolenic acid, palmophoric acid, eicosylenoic acid, linolenic acid, palmitoic acid, The content of 22 carbapentaenoic acid is higher.
