Processing/Packaging Contaminants

Chemical reactions that occur during food processing steps may produce undesirable contaminants. Other contaminants may migrate from packaging containers into food and beverage products. Therefore, food analysts routinely monitor finished products to safeguard that the levels of these contaminants are below regulatory limits. Depending on the food matrix, a cleanup step may be necessary to remove non-target components from the extract prior to analysis, which will help reduce analytical interference.
