Measurement of Fe and Zn in infant nutrient-enriched rice powder by using flame atomic absorption spectrometry

Wang Fangquan et al  
Low-temperature digestion with emulsification was used as the pretreatment of infant cereal samples for measurement of Fe and Zn by using flame atomic absorption spectrometry. The recovery for Fe ranged from 92.7% to 96.6%, and Zn from 93.3% to 98.2%, indicating high reliability for Fe and Zn measurement. Comparing to conventional method, this pretreatment procedure needed only small amount of acid which is 20% of acid used in conventional method and 40% of the acid used in microwave digestion. Less acid can minimize the environmental impact.
