Abstract: In order to explore the sweetening effect of the taste components from yeast extract, free amino
acids, 5'-nucleotides and organic acids in yeast extract were quantitatively analyzed via high-performance
liquid chromatography and amino acid automatic analyzer, and their taste activity value (TAV) was
calculated. The results showed that thirteen taste components exhibited TAV>1, suggesting that these were
the main components contributing to taste perception. Addition of yeast extract with a mass concentration
of 0.1 g/L significantly improved the sweet taste perception of stevioside, mogroside, sucralose, and
shortened the maximum sweetness perception time of stevioside by 2.98 s. Glutamic acid and alanine could
significantly enhance the sweet taste perception of stevioside, mogroside and sucralose, while citric acid
could significantly enhance the sweet taste perception of sucralose. Molecular docking results showed that the
hydrophobic interaction between stevioside and taste receptor type 1 member 2 was enhanced in presence of
glutamic acid or alanine.
