Outline
Pesticide residue detection is a crucial task for ensuring food quality and safety and serves as a vital component of food safety supervision and regulation. Gas chromatography-mass spectrometry is widely employed for pesticide residue detection, yet it is often susceptible to the matrix enhancement effect. Matrix enhancement effects generally lead to overestimated detection results, thereby reducing the accuracy of analytical data and compromising the impartiality of food safety supervision. As a cost-effective, easy-to-operate and highly adaptable method for compensating matrix enhancement effect, the protectants approach has received continuous attention from researchers both at home and abroad. This paper reviewed the discovery and definition of protectants, representative compounds, methods of application, and the factors influencing their compensatory effects on matrix enhancement in the pesticide residue detection by gas chromatography-mass spectrometry. Through a systematic discussion of protectants in pesticide residue analysis, this review aims to provide insights for the development of novel protectants, promote the broader application of the protectant method, and advance the understanding of the mechanisms underlying matrix enhancement effects.
