Description
Jing Cao and colleagues hunted the savory peptides behind Jinhua ham's flavor in a 2026 study combining chemistry and computation. From natural and enzyme-treated ham they cataloged over two thousand peptides, then screened them with machine learning models and virtual docking against the umami taste receptor. Ten candidates emerged from the funnel.
Tasters and an electronic tongue confirmed that all ten carried distinct umami character. Their taste thresholds sat well below that of MSG, meaning a little goes further. Docking showed the peptides gripping the T1R1/T1R3 receptor far more strongly and stably than MSG, mainly through hydrogen bonds anchored on two key receptor residues. The authors say the work explains part of the ham's prized savoriness and supports using such peptides as natural flavor enhancers.
