摘要： Unclear taste mechanisms of peptides limit rapid screening of taste peptides with high intensity. In this study, the taste mechanisms of umami and bitter peptides from Chouguiyu were compared. After molecular docking of core umami (NWDDMEK, WFKDEEF, EEEKPKF, DFDDIQK, and DGEKVDF) and bitter (VQDVLKL, VELLKLE, LVVDGVK, VVDLTVR, and VVDGVKL) peptides with T1R1/T1R3 and TASR14, respectively, salt bridges and conventional hydrogen bonds were the main interactions in all taste peptides, in which acidic amino acid residues contributed to the interaction with their receptors. The taste intensity of peptides after solid-phase synthesis was further verified using electronic tongue technology. Spearman correlation analysis showed that docking energy was an important factor for the intensity of taste peptides, while interaction energy and the distance between the binding unit (BU) and the stimulating unit (SU) were also responsible for the bitter intensity. This study provides a theoretical basis to screen novel taste peptides with high taste intensity in fermented foods.
