| 通过查阅国内外官方食物成分数据库，同时综合近年来国内对成品食用植物油中不同生育酚和生育三烯酚含量进行分析的文献，建立常见食用植物油维生素E异构体成分表。结果表明：国内外现有数据库中食用植物油种类及其生育酚和生育三烯酚数据均不全，且不同地区含量存在明显差异。通过对国内最新研究汇总，共收集22种合计659个常见食用植物油的α-、β-、γ-、δ-生育酚数据，同时收集17种合计183个食用植物油的α-、（β+γ）-、δ-生育三烯酚数据。生育酚广泛存在于植物油中，以α-生育酚和γ-生育酚为主，但不同植物油中含量情况存在明显差异；生育三烯酚主要存在于棕榈油、米糠油和葡萄籽油中，在其他植物油中分布很少。不同类型食用植物油的选择会明显影响人体活性VE总量和不同异构体的摄入情况，目前国内外食用植物油VE异构体数据库有地区差异且均不能覆盖目前常见的食用植物油种类，更新常见成品食用植物油VE数据库很有必要。 |
| 英文摘要: |
| A vitamin E isomer composition database of common edible vegetable oils was established through consulting the worldwide official food composition databases and reviewing the latest literatures on the contents of different tocopherols and tocotrienols in edible vegetable oils. The results showed that available food composition databases all reported limited types of edible vegetable oil with incomplete contents of tocopherols and tocotrienols, indicating obvious regional variances. Through summarizing the latest Chinese studies, the contents of α-, β-, γ-and δ-tocopherols were collected for 22 types of plant oils(n=659) and the contents of α-,(β+γ)-, δ-tocotrienols were collected for 17 types(n=183). Tocopherols, dominated by α-tocopherol and γ-tocopherol, were widely found in various types of vegetable oils with great content differences. Tocotrienols, however, mainly existed in palm oil, rice bran oil and grape seed oil and were rarely found in other vegetable oils. The choice of different types of edible vegetable oil affected the intake of total VE and individual isomers. At present, the official databases indicated regional differences and could not cover the common edible vegetable oil species. It was necessary to update the VE database of common edible vegetable oil products. |
