Zusammenfassung:•Chinese concentrated apple juice was classified to verify origin.•Combination of stable isotopic and mineral elemental improved model performance.•PLS-DA models were used for evaluation.•The key variables tracing the origin of Chinese concentrated apple juice were identified. Food traceability is an important component of food safety and quality. Currently, there is no authentic established technique to identify the origin of concentrated apple juice (CAJ) in China. In this study, the isotopes of δ13C, δ18O and the contents of 32 elements in CAJ from five production areas (BHB, NWR, SCH, LP and YRAR) were determined. The δ13C, δ18O and 28 elements were significantly different (P
