ABSTRACT

Real beef soup samples were separately supplemented with 5-nucleotides extracted from mushroom before and after extraction of soluble sugars (NM and NMs, respectively) and yeast extract. Headspace volatiles and flavour palatability of each sample were compared with beef soup supplemented with 5-IMP and control sample. Each investigated enhancer revealed significant release of thiol-containing compounds. 3-Mercapto-2-butanone was the major identified compound in the headspace volatiles of all samples. However, the sample supplemented with 5-IMP + NM showed the highest release of this compound followed by S-NM compared with other samples. The high palatability of sample S-NM may be correlated to the high content of 2-methyl-3-furanthiol.
