摘要
Abstract
[Objective] To determine contents of Fe and Zn in infant formula milk power. [ Method ] Amounts of iron and zinc in 6 brands of infant milk powder were determined by flame atomic absorption spectrometry. The samples were treated by ashing and ashing temperature was determined. [Result] The results showed that ashing temperature of 450 -500 twas suitable for determining iron and zinc in infant formula; for various growth stages of infant formula milk powder with same brand for the same manufacturer, iron content exhibited some difference and zinc content showed significant difference; for various brands of baby formula, iron and zinc content had no significant difference; but for children infant formula, amounts of iron and zinc exhibited significant difference. The values determined in 6 brands of infant milk powder were in agreement with the requirements of national standard GB/T5413.21-1997, [Conclusion] Scientifically and comprehensively evaluating Fe, Zn content in infant formula milk power has positive significance on quality assessment and guidance for consumption.关键词
