中文摘要:

      目的 分析美藤果油中的主要营养成分(脂肪酸、植物甾醇和维生素E)并与常见食用植物油(大豆油、花生油、菜籽油、芝麻油、橄榄油)的营养成分进行比较。方法 基于国家标准与文献报道的方法对植物油中的脂肪酸、植物甾醇和维生素E进行检测。结果 美藤果油的亚麻酸含量(43.62%)高于常见食用植物油, 不饱和程度高, 脂肪酸组成合理。植物甾醇含量为265.61 mg/100 g, 高于花生油和橄榄油, 且豆甾醇、维生 素E含量都明显高于其他常见食用植物油。维生素E总含量为122.73 mg/100 g, 其中δ-生育酚含量最高 (59.69 mg/100 g)。结论 美藤果油不饱和脂肪酸含量高, 富含亚麻酸、植物甾醇和维生素E。与常见食用植物油相比, 美藤果油在一定程度上具有更好的营养保健价值, 是一种优质的植物油。

英文摘要:

      Objective To analyze the main nutritional components (fatty acids, phytosterol and vitamin E) in the sacha inchi oil, and compare them with common edible vegetable oils (soybean oil, peanut oil, rapeseed oil, sesame oil, and olive oil). Methods According to national standards and literature reports, the contents of fatty acids, phytosterols and vitamin E of sacha inchi oil were detected, respectively. Results The sacha inchi oil had the higher content of linolenic acid (43.62%) than common edible vegetable oils, which had high degree of unsaturated, and the composition of fatty acids was reasonable. The content of phytosterol in the sacha inchi oil was 265.61 mg/100 g, which was higher than that of peanut oil and olive oil, and the contents of stigmasterol and vitamin E were significantly higher than those of other common edible vegetable oils. The total content of vitamin E was 122.73 mg/100 g, and the content of δ-tocopherol was the highest (59.69 mg/100 g). Conclusion The content of unsaturated fatty acid is high in sacha inchi oil and it is also rich in linolenic acid, phytosterol and vitamin E. Because of its better nutritional value, it is a kind of high quality vegetable oil compared with common edible vegetable oils.
