| 中文摘要: |
| 本实验主要对冬瓜籽油的理化性质、脂肪酸组成及营养成分进行分析。测定结果表明：冬瓜籽油酸价为4.96 mg/g,过氧化值为0.02 g/100 g,皂化值为195.97 mg/g,碘值为111.22 g/100g；冬瓜籽油中包含12种脂肪酸,其中以亚油酸为主要脂肪酸,不饱和脂肪酸含量高达81.83%；冬瓜籽油还含有丰富的植物甾醇,其中菜油甾醇含量最高,为2255.50 mg/kg,豆甾醇含量为980.76 mg/kg；冬瓜籽油中共检出3种生育酚,其中γ-生育酚含量最高(612.9 mg/kg),其次为α-生育三烯酚(90.6 mg/kg)；冬瓜籽油中多酚类物质的含量为56.4mg GAE/kg油。 |

| In this experiment, the physicochemical properties, fatty acid composition and nutrient composition of wax gourd seed oil were analyzed. The results showed that the wax gourd seed oil had an acid value of 4.96 mg/g, a peroxide value of 0.02g/100 g, a saponification value of 195.97 mg/g, an iodine value of 111.22g/100 g, and wax gourd seed oil containing 12 fatty acids. Linoleic acid as the main fatty acid, unsaturated fatty acid content of 81.83%; wax gourd seed oil is also rich in phytosterols, which highest content of campesterol(2255.50 mg/kg), stigmasterol content of 980.76 mg/kg; Three tocopherols were detected in wax gourd seed oil, with the highest γ-tocopherol content (612.9 mg/kg), followed by α-tocotrienol (90.6 mg/kg); the content of polyphenols in wax gourd seed oil was 56.4 mg GAE/kg oil. |
