Research Progress on the Removal Effect of Different Cleaning Methods on the Pesticide Residues in Fruits and Vegetables

Abstract:

Fruits and vegetables are an important and indispensable food source in the diet of Chinese residents, and pesticides play a key role in ensuring the efficiency of fruit and vegetable production. With the improvements of living standards and scientific and technological means, the problems of pesticide residues in fruits and vegetables and their removal have attracted much attention. This study systematically summarizes the current situation of pesticide residues in fruits and vegetables, the cleaning methods for removing pesticide residues, the principles, advantages and disadvantages of various methods, and future development directions. The research results show that emerging pesticide residue removal technologies such as ultrasound, ozone, non-thermal plasma, and electrolytic water cleaning have shown significant effects in fruit and vegetable cleaning applications. However, the degradation rate and deactivation degree of pesticide residues by these technologies are also influenced by multiple factors such as equipment type, processing parameters, surface characteristics of fruit and vegetable products, treatment conditions, and pesticide properties. In order to remove the pesticide residues on food surface more effectively, further research is needed on the applied technologies to deal with the complicated types of pesticide residues in order to provide consumers with more accurate and feasible cleaning methods.
