Food safety issues caused by pesticide residue have exerted far-reaching impacts on human daily life, yet the available detection methods normally focus on surface residue rather than pesticide penetration to the internal area of foods. Herein, we demonstrated gold nanoparticle (AuNP)-immersed paper imprinting mass spectrometry imaging (MSI) for monitoring pesticide migration behaviors in various fruits and vegetables (i.e., apple, cucumber, pepper, plum, carrot, and strawberry). By manually stamping food tissues onto AuNP-immersed paper, this method affords the spatiotemporal visualization of insecticides and fungicides within fruits and vegetables, avoiding tedious and time-consuming sample preparation. Using the established MSI platform, we can track the migration of insecticides and fungicides into the inner region of foods. The results revealed that both the octanol-water partition coefficient of pesticides and water content of garden stuffs could influence the discrepancy in the migration speed of pesticides into food kernels. Taken together, this nanopaper imprinting MSI is poised to be a powerful tool because of its simplicity, rapidity, and easy operation, offering the potential to facilitate further applications in food analysis. Moreover, new perspectives are given to provide guidelines for the rational design of novel pesticide candidates, reducing the risk of food safety issues caused by pesticide residue.

Accuracy And Stability

To investigate the stability of the pesticide residue in storage samples is a part of detection, which is also an improvement to the accuracy of analytical results. In this work, the UPLC-MS/MS method with perfect accuracy and stability was established for determining residues of difenoconazole in mango. The stability of the residue under different temperatures (4°C and −20°C) and media (fruit samples and pretreated sample solution) was investigated. At 0.1 mg/kg, the residue degraded in 6 months by 12% when at −20°C, while in a week by only 12.2% at 4°C. However, when pretreated and preserved in the solution, the residue remained more than 90% for 6–8 weeks. The results indicated that the main causes of degradation are biochemical factors, and the factors are affected by temperature. The findings also provided appropriate conditions for sample storage. This investigation promotes the accuracy in detection and hence guarantees food safety and quality.

Residue Levels

One type of pesticide that is widely used is a group of organophosphates with chlorpyrifos as the active ingredients, because it has more favorable characteristics such as easy to decompose and short persistence time. However, the use of pesticides in addition to leaving residues that can cause environmental pollution, also cause disruption to human health and inhibit trade. Therefore, it is necessary to monitor the use of pesticides through the fulfillment of the maximum residual limit (MRL) so as to ensure food safety by limiting pesticide residue levels on agricultural products. The purpose of this study was to determine the residual levels of chlorpyrifos in cabbage vegetables with previously optimized and validated HPLC methods. The sample of this research is vegetable cabbage taken from several traditional markets in North Sulawesi. Based on the results of the study, it was found that chlorpyrifos were detected in all samples analyzed, although the levels were still below the specified MRL value.  The results of this study can be a consideration for consumers and relevant agencies in North Sulawesi to more frequently monitor and evaluate the existence and use of these compounds.
