| 中文摘要: |
| 以芝麻、花生、油茶籽、油菜籽为原料，通过热榨工艺与冷榨工艺制取油脂，比较分析不同工艺制取油脂的基本理化指标、主要脂肪酸组成及含量、总酚含量、生育酚含量、甾醇含量。结果表明：不同制油工艺对4种原料制取的油脂的基本理化指标及主要脂肪酸组成及含量没有明显影响；热榨菜籽油、热榨芝麻油、热榨花生油、热榨油茶籽油的总酚含量分别是冷榨工艺的4.76、2.08、299、1.17倍；冷榨花生油、冷榨油茶籽油、冷榨芝麻油、冷榨菜籽油的生育酚含量分别是热榨工艺的1.19、1.17、1.12、1.07倍；冷榨芝麻油、冷榨花生油、冷榨油茶籽油、冷榨菜籽油中甾醇含量分别是热榨工艺的1.21、1.29、1.27、1.20倍。 |
| 英文摘要: |
| With sesame, peanut, oil-tea camellia seed and rapeseed as raw materials, oils were extracted by hot pressing process and cold pressing process, and the basic physicochemical indexes, composition and contents of main fatty acids, polyphenol content, tocopherol content and sterol content of the oils were compared and analyzed. The results showed that different preparation processes had no significant effect on the composition and contents of main fatty acids and basic physicochemical indexes of oils extracted from the four materials. The contents of polyphenols in hot pressed rapeseed oil, hot pressed sesame oil, hot pressed peanut oil and hot pressed oil-tea camellia seed oil were 4.76，2.08，2.99，1.17 times of the cold pressed oils respectively. The contents of tocopherol in cold pressed peanut oil, cold pressed oil-tea camellia seed oil, cold pressed sesame oil and cold pressed rapeseed oil were 1.19，117，1.12，1.07 times of the hot pressed oils respectively. The contents of sterol in cold pressed sesame oil, cold pressed peanut oil, cold pressed oil-tea camellia seed oil and cold pressed rapeseed oil were 1.21，129，1.27，1.20 times of the hot pressed oils respectively. |
