据欧盟食品安全局（EFSA）消息，5月7日欧盟食品安全局就活性物质铁粉、活性炭、煅烧高岭土、氯化钠、交联聚丙烯酸钠盐、氯化钙作为活性系统用于食品接触材料的安全性评估发表科学意见。
专家组经过评估得出结论认为，该活性系统的使用不会对人体健康构成威胁。
部分原文报道如下：
The CEF Panel concluded that the use of substances iron powder, activated carbon, calcined kaolin, sodium chloride, polyacrylic acid, sodium salt, crosslinked and calcium chloride does not raise a safety concern when used in oxygen absorbers in labels, which prevent the physical release of their content into the food. When placed in the headspace of the packaging or when used in direct contact with foods, the labels should not intentionally or unintentionally come into direct contact with liquid foods or foods that have an external aqueous phase on the surface such as sliced fruits.
Activated carbon should in addition comply with the same purity requirements as for Vegetable Carbon （E 153） set out by Commission Regulation （EU） No 231/2012 with exception of ash content which can be up to 10 % （w/w）。
Iron is a natural constituent of foods. Iron compounds are also used as food additives, nutrient sources and for other purposes. The Commission may wish to take note of this if setting a restriction for iron.
