(1) Background: At the time of harvest, stems broccoli are frequently discarded. (2) Methods: In this study, sulforaphane content and glucosinolate profile were analyzed at different temperature treatments. (3) Results: Thermal treatment for 1 h resulted in maximal 50 °C, with a subsequent progressive reduction concentration correlating to elevated temperatures. Metabolomic analysis was conducted on stem samples subjected 25 °C (CK), 80 Among identified GSLs, °C-treated demonstrated significantly reduced GSL accumulation, whereas group exhibited retention. Indole derivatives predominated among three subclasses (aliphatic, aromatic, indole), accounting approximately 70% total GSLs across all groups. The observed depletion correlated enhanced biosynthesis. Comparative further indicated that induced more pronounced elevation indole compared aliphatic aromatic counterparts stems. (4) Conclusions: results exhibit superior thermal stability. Moderate treatments effectively enhance content, exposure increases content.
