Abstract

Nickel is used in the production of margarine as a catalyst for hydrogenation. This may lead to the presence of its residues in the products and could cause allergic reactions. Therefore, monitoring of this metal in foods is essential for consumers. The described liquid sampling AAS procedure allows product control. Nickel was determined in 10 brands of margarine, and only in 3 samples its content was below the acceptable limit of 0.2 mg kg(-1).

摘要

镍在人造黄油生产中用作氢化催化剂。这可能导致其残留物存在于产品中，并可能引发过敏反应。因此，对食品中的这种金属进行监测对消费者至关重要。所描述的液体采样原子吸收光谱法程序可实现产品控制。对10个品牌的人造黄油中的镍进行了测定，只有3个样品中的镍含量低于0.2毫克/千克的可接受限量。
