TastepepAI: An artificial intelligence platform for taste peptide de novo design
Fig 5
Electronic tongue analysis reveals concentration-dependent taste profiles of TastePepAI-generated peptides.
Taste characteristics of 73 peptides at two concentrations (0.1 mg/mL and 1 mg/mL). The intensity of each taste modality (sour, sweet, bitter, salty, and umami) is represented by colored dots, where the size reflects the quartile distribution of positive taste scores: large filled dots (75th-100th percentile), medium filled dots (50th-75th percentile), small filled dots (25th-50th percentile), and tiny dots (0-25th percentile). Large empty circles indicate undetected taste responses. At 0.1 mg/mL concentration, all peptides exhibited sweet and umami characteristics, whereas at 1 mg/mL concentration, a universal salty response was observed across all samples.
