Distribution and Quantification of Pesticides in Processed Wheat Grain Fractions

摘要

Food safety is an area of growing worldwide concern on account of its direct bearing on human health. The presence of harmful pesticide residues in cereals has caused a great concern among the consumers. For investigating the carryover of pyretroids, organochlorine and organophosphorus pesticide residues in the cereal food chain from grain to consumer, a study was set up on seven varieties of Romanian wheat. Over each variety of grain it was added a mix of pesticides. The residue levels of pesticides were determined in processed wheat grain fractions: bran, semolina and flour. The goal was to assess the absorption quantity of pesticide mixtures and their distribution in wheat fractions. The pesticides concentrations were below the maximum residue limits (MRLs) for wheat. The highest amounts of pesticides were present in bran and the least in flour.
