Food products. Determination of ochratoxin A in cereal-based foods for infants and young children. HPLC method with immunaffinity column purification and fluorescence detection

This technical specification establishes a precise analytical procedure for determining Ochratoxin A concentrations within cereal-based foods designed for infants and toddlers. The method integrates high-performance liquid chromatography with fluorescence detection, utilizing immunosorbent column purification as a critical sample preparation step to ensure high sensitivity and specificity. By focusing on food products intended for young children, this document addresses the need for rigorous monitoring of mycotoxin contaminants in delicate dietary items. The protocol outlines specific operational parameters, reagent requirements, and calibration procedures necessary to achieve accurate quantification. It serves as a reference for laboratory professionals tasked with compliance testing in the food safety sector, particularly within regions adopting harmonized European analytical guidelines. The approach described minimizes interference from complex food matrices, thereby enhancing the reliability of检测结果 in routine quality control environments. Implementation of this methodology supports broader public health objectives by facilitating early detection of potential toxins in early-stage nutrition products.
