“…In the pickling trial, the concentrations of mandipropamid were slightly reduced in cucumber, Chinese cabbage, and cowpea samples over the pickling time. Microbiological degradation may be the main pathway for removing pesticide residues from vegetables in the pickling process [ 21 ]. Different reduction efficiencies were obtained for the analyte in different vegetables, which might be related to the characteristics of the vegetables [ 20 , 22 ], such as specific bacteria generated after pickling different vegetables [ 5 ].…”

“…The contaminated cucumber samples were cut into small pieces with an average size of approximately 1 cm 3 , and the contaminated Chinese cabbage and cowpea samples were drained as the raw material of sauerkraut [ 20 , 21 , 22 , 23 ]. The pretreated vegetable samples were pickled in 10% NaCl solution in a 5 L fermentation tank stored in the dark at 25 °C.…”

The study aimed to detect the content of mandipropamid enantiomers in unprocessed and processed tomato, cucumber, Chinese cabbage, and cowpea samples and assess the health risks to Chinese consumers. Data showed that washing and soaking with an acidic solution reduced the mandipropamid residue from vegetable samples by 54.1–82.2%. The pickling process resulted in a 6.2–65.2% loss of mandipropamid from cucumber, Chinese cabbage, and cowpea samples. Peeling and juicing were the best removing techniques for mandipropamid residues in tomato and cucumber (removal rate (RR) value > 91%), and cooking for 5 min could effectively reduce the levels of mandipropamid in Chinese cabbage and cowpea (RR values of 81.4–99.7%). The values of processing factor for the processed vegetable samples are all less than one. No significant enantioselectivity of mandipropamid was found in the vegetables during processing. Health risk data showed that samples of four types of mandipropamid-contaminated vegetables were safe for consumption after processing.

Pesticide residues in food can bring potential risks to human health and has been widely concerned in recent years. In the current study, the influence of paclobutrazol, which resided in raw material (grape) on wine fermentation process, were investigated. The degradation kinetic results indicated that the enantiomers of paclobutrazol not be degraded during 30 days of fermentation process. In order to achieve the fermented microorganism information of diversity, community composition, and function, the analysis of 16S rRNA and ITS sequencing were performed. Results demonstrated that the dominant microorganisms multiplied and the microbial diversity in the samples decreased as the fermentation process progresses. Furthermore, the paclobutrazol stimulated the growth of Pichia, which was observed during wine fermentation and which may have an underlying impact on the quality of the wine. The above results inferred that paclobutrazol residue could disturb the microbial community stability during wine fermentation, and the stable existence of paclobutrazol will cause potential risks to food safety and human health. In this work, we have successfully devised a method to investigate the influences of pesticide residues in raw materials during food processing and conclusions from this study could provide basis for dietary risk assessment.

Chiral pesticides have the special chiral structures, so enantioselective biological effects are usually observed in living organisms. Current study used paclobutrazol as a case study and explored the enantioselective degradation and oxidative stress effect on wheat. The results demonstrated that the degradation of R‐paclobutrazol was faster than S‐paclobutrazol significantly and improved the content of MDA and O2− in wheat plants, which proved that the R‐paclobutrazol induced oxidative damage in wheat, showing selective biological effects, and S‐paclobutrazol was friendly to wheat. This study provided a theoretical basis for the selective activity of chiral pesticides and the development of chiral pesticide monomers.
