在单因素试验基础上,采用响应面分析法对木洞杨梅核仁油浸提条件进行优化,分析了浸提时间、料液比及浸提温度等3个因素对杨梅核仁得油率的影响;并采用气相色谱法对杨梅核仁油的脂肪酸组成进行分析。根据单因素试验及响应面分析得出最佳浸提工艺条件为浸提时间2 h 20 min、料液比1:7.5 (m/V)、浸提温度48.5 ℃,此条件下的杨梅核仁油得油率高达62.52%,即提取率为93.31%。脂肪酸组成分析结果表明:木洞杨梅核仁油富含不饱和脂肪酸,高达86.49%,其中油酸的质量分数达47.9%,亚油酸质量分数达到37.3%,且含有少量亚麻酸(0.12%)、花生一烯酸(0.29%)、棕榈一烯酸(0.88%),具有较高的营养价值。

Based from single factors of Mudong Bayberry seed oil extraction experiments, three extraction parameters, extraction time, liquid/solid ratio and extraction temperature were optimized by response surface methodology. Myribra Rubra seed oil fatty acid composition was analyzed by gas chromatography. The optimal extraction conditions for oil yield were time, liquid/solid ratio, temperature as 2 h 20 min, 1∶7 (m/V) and 48.5℃. Under the optimum condition, the experimental oil yield was 62.52% and the extraction yield was 93.31%. The fatty acid co...
