摘要
本文研究了不同糖类（半乳糖、葡萄糖、果糖、蔗糖、乳糖）在体外消化过程中对铁化学状态及透析率的影响。结果表明，糖类的存在可促进铁的溶解及Ｆｅ３＋还原为Ｆｅ２＋，其作用大小依次为：半乳糖＞葡萄糖＞果糖＞蔗糖＞乳糖。半乳糖和葡萄糖可显著提高可溶性铁的透析率（Ｐ＜０．０１和Ｐ＜０．０５），其余糖类无显著作用；对于二价铁的透析率来说，具有显著促进作用的糖类依次为：半乳糖＞乳糖＞蔗糖＞果糖，葡萄糖则无显著效果。
The effects of different sugars on chemical form and dialyzation of iron in vitro digestion were investigated.Results showed that all sugars used in this study could improve the solutability of iron and reduction of ferric to ferrous,the order of these actions was :galactose >glucose>frucose>sucrose>lactose.Galactose and glucose could significantly increase the dialyzation of iron.
