This invention belongs to the field of biotechnology, specifically relating to a salty peptide from *Flammulina velutipes*, its preparation method, and its application. Water-soluble substances were extracted from different varieties of *Flammulina velutipes* using a high-pressure cooking method. The salty-umami peptides in *Flammulina velutipes* were then separated stepwise using ultrafiltration, gel chromatography, sensory evaluation, and electronic tongue analysis. Seventy-two peptides were identified using reversed-phase liquid chromatography-mass spectrometry. Two key peptides were selected for solid-phase synthesis through molecular docking with transmembrane channel-like protein 4. Electronic tongue and sensory evaluation results showed that the flavor thresholds of both synthesized peptides were higher than those of NaCl, exhibiting excellent saltiness-enhancing effects. Molecular dynamics simulation analysis of the flavor mechanism between the salty peptides and the TMC4 receptor revealed that the interaction between the peptides and the TMC4 receptor is mainly driven by hydrophobic interactions.
