婴幼儿配方乳粉中叶黄素的损失率及影响因素分析

Loss Rate of Lutein in Infant Formula Milk Powder and Its Influencing Factors

试验研究了叶黄素在婴幼儿配方乳粉生产过程和货架期的损失率,分析了影响叶黄素稳定性的因素。结果表明:婴幼儿配方乳粉中叶黄素对温度、氧气比较敏感,在湿法工艺下经喷雾干燥过程叶黄素有一定程度的损失;充氮包装与不充氮包装样品在相同的温度条件下储存,损失率存在明显差异;在储存6个月时,产品中叶黄素的损失率达到最高。

The loss rate of lutein in infant formula milk powder during production process and shelf life was studied,and the factors affecting the stability of lutein were analyzed.The results showed that lutein was sensitive to temperature and oxygen.Lutein had a certain degree of loss in spray drying process under the wet process.There was a significant difference in the loss rate of nitrogen filling and non nitrogen packing samples under the same temperature condition.The loss rate of lutein reached the highest level at 6 months during storage process.
