베이킹파우더, 등급별 밀가루 및 몇 가지 밀가루 가공식품에 대한 알루미늄 함량을 조사하고자 $HNO_3:HClO_4(v/v,;2:1)$ 혼산으로 분해하여 원자흡수분광광도법으로 분석하였다. 원료와 가공식품들의 알루미늄 함량은 베이킹파우더는 $1910{sim}1948mg/100g$, 중력분은 8.5mg/100g, 강력분 박력분은 각각 10.8 mg/100g, 11.0 mg/100g이며 국수는 $29.7{sim}58.5mg/100g$, 라면은 $63.0{sim}80.0mg/100g$, 당면은 $33.1{sim}46.3mg/100g$, 냉면이 $37.8{sim}49.9mg/100g$, 비스켓과 스낵은 $15.3{sim}19.2mg/100g$, $22.5{sim}56.4mg/100g$ 범위였다. 밀가루 식품중의 알루미늄 함량은 동일 식품이더라도 제조회사에 따라서 함량차이를 인정할 수 있었다(p<0.01).
The purpose of this study was to investigate aluminum content by atomic absorption spectrophotometry after digestion with mixture of $HNO_3;and;HClO_4(2:1,;v/v)$ on baking powder, wheat flours, noodles and baked foods. The contents of aluminum in baking powder, wheat flour, biscuit and snack, noodle, starch vermicelli, buckwheat vermicelli ranged from 1910 to 1948 mg/100g, 8.5 to 11.0 mg/100g, 15.3 to 19.2 mg/100g and 22.5 to 56.4 mg/100g, 29.7 to 58.5 mg/100g, 63.0 to 80.0 mg/100g, 33.1 to 46.3 mg/100g, 37.8 to 49.9 mg/100g, respectively. Aluminum contents in wheat flour foods were significantly different by added baking powder and different company(p<0.01).
