摘要
通过单因素实验和响应面分析对浓香菜籽油制备工艺进行优化,检测分析其挥发性风味成分。结果表明:影响风味的因素顺序为炒籽时间>炒籽温度>入榨水分,炒籽时间与炒籽温度均对风味有交互影响且影响极显著。最佳炒籽时间、温度、入榨水分分别为30min、170℃和5%,所得菜籽油的感官评分为95分,略高于94.3583分的模型预测结果,共含有69种挥发性风味成分,其中硫苷降解物相对含量为58.36%,醛类相对含量为13.42%,其它风味成分相对含量为27.54%。
The preparation process of Fragrant rapeseed oil was optimized by single factor experiment and response surface analysis method,and the volatile flavor components were detected and analyzed.The results revealed that the order of influencing the flavor is:roasting time>roasting temperature>material moisture,roasting time and roasting temperature have an interactive effect on the flavor and the effect is extremely significant.The best time for roasting seeds,temperature and material moisture were 30 min,170℃,and 5% respectively.The sensory score of the obtained rapeseed oil was 95 points,slightly higher than the prediction result of the model of 94.3583 points.There are 69 kinds of volatile flavor components in total,of which the relative content of glucosinolate degradation products is 58.36%,the relative content of aldehydes is 13.42%,and the relative content of other flavor components is 27.54%.
