Abstract
The geographical origin of chili peppers influences the sensory quality of Sichuan hotpot in beef tallow systems, yet systematic evaluations remain limited. Chili peppers from six Chinese origins (WS, KS, JT, YM, AKS, and AM) were evaluated after thermal processing with beef tallow. Color parameters, capsaicin content, and volatile profiles were analyzed using GC × GC-MS, GC-IMS, and E-nose, and 18 compounds with rOAV ≥1 were screened as key aroma contributors. PLS-DA clearly differentiated the six samples by origin. Entropy weight-TOPSIS ranking was highly indicator-dependent: excluding volatiles detected in fewer than three origins changed the ranking from YM > WS > KS > JT > AKS > AM to WS > AKS > YM > KS > JT > AM. These findings show that origin-associated quality differences in chili-beef tallow systems are multidimensional and detectable under standardized processing, while composite rankings based on sparse volatile data should be interpreted with caution.
