Novel umami ingredients: umami peptides and their taste. Journal of Food Science. 82:16–23. doi:10.1111/1750-3841.13576. Interpretive Summary: This article reviews the current status of research on umami peptides and their tasting characteristics Umami substances are very important for food seasoning and healthy eating. In addition to monosodium glutamate (MSG) and some nucleotides, recent investigations have found that several peptides also exhibit umami taste. There are 52 reported peptides showing umami taste in recent years, including 24 dipeptides, 16 tripeptides, 5 octopeptides, 2 each of pentapeptides and hexapeptides, and one each of tetrapeptides, heptapeptides and eleven (undeca) peptides. Twenty of these peptides were questioned for existence of umami taste. In this review, we have enlisted thesespeptides showing umami taste based on their category, source, taste and threshold concentrations. The possible evidences of peptides showing umami tastes, the umami taste receptors in human tongue, and the peptides which are in controversy over their umami tastes are also discussed.
