食用油监管添“利器” 掺假1%也能查出来

Core Viewpoint - The research team from the China National Institute of Standardization has developed a high-sensitivity authenticity identification technology system for edible oils, enhancing quality safety regulation and providing strong technical support for daily supervision and special rectification efforts [1] Group 1: Technological Advancements - The research team integrated non-targeted metabolomics and lipidomics technologies to create a fingerprint database covering over 200 lipid components and metabolites [1] - An innovative compound electronic activation dissociation multiple fragmentation model was proposed, establishing a collaborative identification method based on "lipid component profiles + characteristic compounds" [1] Group 2: Practical Applications - The team developed identification models for 10 common edible oils, including peanut oil, camellia oil, and olive oil, successfully controlling the detection limit of adulteration to 1% or below [1] - The technology has been applied in risk monitoring and special rectification of edible plant oils, covering various scenarios such as pre-packaged oils on supermarket shelves, bulk oils used in restaurants, and high-end plant oils sold online [1] Group 3: Impact on Regulation - The research outcomes have been incorporated into the risk monitoring technical system for adulteration in edible oils, providing robust technical support for identifying and rectifying issues related to adulteration and substandard products [1]
