婴幼儿配方乳粉加速试验营养素变化初探

Preliminary Study on Nutrients in Infant Formula Milk Powder Accelerated Experiment

大部分对食品货架期的研究均是以温度为加速因子,在37℃条件下考察了婴幼儿配方乳粉的保质期。在该试验过程中,婴幼儿配方奶粉中维生素B12、碘和叶黄素的变异系数较大,维生素B12可能为检测偏差导致的,碘和叶黄素可能为加速试验过程中营养素衰减,导致变异系数较大。

Most of the research on shelf life of foods was based on temperature as the acceleration factor.The shelf life of infant formula milk powder was investigated at 37℃.During the test,the coefficient of variation of vitamin B12,iodine and lutein in infant formula was larger,vitamin B12 may be caused by detection bias,and iodine and lutein may cause the coefficient of variation of nutrient decay during accelerated test.
