| 摘 要： | 以葡萄籽为原料,采用两种方法提取葡萄籽油,对其进行甲酯化处理后,应用气相色谱仪测定脂肪酸甲酯的含量,通过其含量来间接测定脂肪酸的相对含量。实验测得不饱和脂肪酸的含量可达64%以上。本实验对超临界二氧化碳萃取的葡萄籽油和溶剂法提取的葡萄籽油其脂肪酸成分进行比较分析,为进一步工业应用提供必要参数。

| Abstract: | The grape seed oil is extracted by two methods. After the extracted oil is methyl esterized, its fatty acids could be measured by means of gas chromatograph, the result of fatty acids is above 64%.It also analyzed composition of grape seed oil which is extracted from supercritical CO2 extraction and impregnation, all will offer needed parameter for industry. |
