油脂在脱臭后反式脂肪酸的生成及维生素E的损失问题的探讨

叙述了在油脂脱臭过程中油中顺式脂肪酸 转化成反式脂肪酸以及油中维生素Ｅ的损失问题。另外，还提出了用用新式填料式脱臭塔替代目前常用的盘式脱臭塔问题，因为前者的水蒸汽耗用量少，反式脂肪酸生产量也少，并生育保留量却较多，其优越性是很明显的。

Investigation on Formationof Trans-acids andTocopherol Loss During Deodorization

This paper describes the formation of trans fatty acids from cis fatty acids (the more polyunsaturated it has,the more trans fatty acids will be formed),and the tocopherol loss problems during the oil deodorization process.In addition,a new packed deodorization column has been discussed to replace the tray type deodorizer for its less amount of steam consumption,less trans fatty acids formation and more tocopherols be reserved.So,the packed deodorization column's advantages are obvious.
