In this study, we used ultra-performance convergence chromatography coupled with triple quadrupole mass spectrometry to determine the content of the novel chiral acaricide cyflumetofen. The matrix-matched calibration lines were constructed for apple slices, juice, wine and vinegar, and the determination coefficients (r2) exceeded 0.9954. Acceptable average recoveries were within 81.1% to 119.9%, and the relative standard deviations (RSDs) ranged from 0.8% to 11.0%. Processing effectiveness is represented by the processing factor (PF). The results indicated that the PFs of different procedures (washing, peeling, enzymolysis, fermentation, among others.) were generally less than 1. The reduction of cyflumetofen enantiomers during fermentation was in accordance with first-order kinetics, and stereoselective behavior was observed. This study provides reliable references for the risk assessment of cyflumetofen in the processing of apple products. Lake deposits, plant-based ashes, filtrates and evaporites or alkaline salts are used traditionally in food preparations by local populations in Africa, Asia, South America, and Oceania. Depending on the context, traditional alkaline salts are used to reduce cooking times, improve rheological characteristics of starchy doughs, maintain the color of vegetables, improve the viscosity of sticky vegetables, and act as emulsifiers. This review highlights some of the relationships among chemical composition and physicochemical properties of traditional alkaline salts when used in solution as well as their functionalities. In addition, their potential toxicity and physiological effects are explored, which might lead to a better understanding of some previously unexplained functionalities and future trends in research, such as their impact on human hea
