In addition,
an increase in VOCs production was observed especially in the generation
of compounds derived from amino acid degradation (3-
methylbutanoic acid, methional and benzothiazole) and ester activities (ethyl 2-methylpropanoate, ethyl 2-methylbutanoate and
ethyl 3-methylbutanoate). A descriptive aroma profile analysis of
the sausages confirmed the increase of fruity and cured notes in inoculated
reformulated sausages. The results of these studies can be observed
in Fig. 1 where sausages noticeably reduced in fat and salt
differed in flavour acceptance from the ones inoculated with the selected
yeast, whilst control sausages appeared in an intermediate position.
In addition, the aroma descriptors were preferentially related
to the yeast inoculated sausages.
