The objective of this study was to determine the effects of yeast cultures
(
Candida zeylanoides
and
Debaryomyces
hansenii
) isolated from traditionally dry fermented Turkish sucuks,
on some physicochemical and microbiological properties of the product. Eight
different batches of the sucuks were produced by the inoculation of yeast and
lactic acid bacteria (LAB) cultures (
Lactobacillus curvatus
,
Lactobacillus plantarum
and
Lactobacillus
sakei
) in different combinations. The sucuks were ripened for 12
days and analyzed at 1
st
, 6
th
, and 12
th
days of
ripening. Percent moisture content, pH, water activity (a
w
) and
residual nitrite values of the sucuk inoculated with the yeast cultures were
higher at the end of the ripening. The use of yeast cultures decreased hardness,
gumminess, and chewiness values of the sucuk while increased adhesiveness
values. Major volatile groups were aldehydes, terpenes, and sulphur compounds in
the sucuk samples. The most noticeable results were for sensory properties of
the sucuk that were positively improved by the yeast cultures.
