アルミニウム含有食品添加物を使用した食品中のアルミニウム含有量

摘要

ベーキングパウダーを使用した菓子・パン類，ミョウバンを使用した食品として野菜加工食品，海産物などを中心とした105試料について，食品中のアルミニウム（Al）含有量調査を行った．菓子・パン類は57試料中26試料で0.01～0.37mg／g，小麦粉調製品は6試料中3試料で0.22～0.57mg／g，野菜加工食品は3試料すべてで0.01～0.05mg／g，海産物は6試料中4試料で0.03～0.90mg／g，即席めんは11試料中3試料で0.01～0.03mg／g，春雨は4試料中3試料で0.04～0.14mg／g，大豆は不検札　大豆加工食品は16試料中1試料で0.01mg/gのAlが検出された（定量限界0.01mg／g）．週一度摂取すると体重16kgの幼児のPTWIに相当するものが，菓子類2試料，小麦粉調製品2試料，くらげ1試料の5試料あった．以上の結果から．子供，特に幼児では製品や喫食量により，PTWIを超過する可能性があることが示唆された.%The aluminium (Al) content of 105 samples, including bakery products made with baking powder, agricultural products and seafoods treated with alum, was investigated. The amounts of Al detected were as follows (limit of quantification: 0.01 mg/g): 0.01-0.37 mg/g in 26 of 57 bakery products, 0.22-0.57 mg/g in 3 of 6 powder mixes, 0.01-0.05 mg/g in all three agricultural products examined, 0.03-0.90 mg/g in 4 of 6 seafood samples, 0.01-0.03 mg/g in 3 of 11 samples of instant noodles, 0.04-0.14 mg/g in 3 of 4 samples of vermicelli, 0.01 mg/g in 1 of 16 soybean products, but none in soybeans. Amounts equivalent to the PTWI of a 16 kg infant were detected in two samples of bakery products, two samples of powder mixes and one sample of salted jellyfish, if each sample was taken once a week. These results suggest that certain foods, depending on the product and the intake, might exceed the PTWI of children, especially infants.
