既存添加物（着色料）中の有害重金属およびヒ素の含有量調査

摘要

Pollution levels of toxic heavy metals (Pb, Cd, Hg) and arsenic in existing food additives used as food colors (40 samples of 15 kinds) were investigated. Heavy metals were detected in 8 samples; Pb in 1 sample (2.8μg/g), Hg in 8 samples (0.1-34μg/g) and arsenic in 2 samples (1.7, 2.6 μg/g). The Pb level in 1 sample of lac color (2.8μg/g) exceeded the limit of 2μg/g proposed by JECFA and Hg levels in 3 samples of cacao color (1.2-3.4 μg/g) exceeded the limit of 1 μg/g in the EU specification.%調査の結果，15品目40試料中4品目8試料から何らrnかの有害元素が検出された（Table 1）．その内訳は，Asがrn2試料，Hgが8試料，Pbが1試料であった．EUやrnJECFAの規格と比較したところ，カカオ色素3試料のrnHgとラック色素1試料のPbがEUやJECFAで設定さrnれている基準を超えていた．
