Abstract:

In order to detect pesticide residues in agro-products and foods to ensure consumers’ food safety,some fast detection techniques need to be developed urgently. Enzyme inhibition method is one of current main research directions in the rapid detection techniques of pesticide residues. While the immobilized enzyme based on the principle of enzyme inhibition method is an important step in the research of detecting pesticide residue. Applying physical or chemical methods to efficiently fix enzyme on the carrier without losing catalytic activity is the key step to develop all kinds of sensor based on enzyme inhibition method to detect pesticide residues. In this paper,the immobilized enzyme methods,carriers and the practical applications of immobilized enzyme products in pesticide residue detection are reviewed,so as to provide some experiences and references for the applications of immobilized enzyme in pesticide residue detection.

Key words: enzyme inhibition method, pesticide residues, immobilized enzyme
