The influence of different fermentation conditions and cabbage hybrids and
variety, ?Tenacity?, ?Bravo? and ?Futoski?, on physico-chemical properties
of cabbage heads was studied in this research. Experiment was set up in
industrial conditions. Samples 1T, 4B and 7F were obtained by spontaneous
fermentation with 3.3% NaCl solution, samples 2T, 5B and 8F were obtained
with brine from previous cabbage fermentation and samples 3T, 6B and 9F were
treated with 100 mL of lactic-acid starter culture onto 3.3% NaCl solution.
Previous cabbage fermentation was done with 3.3% of salt solution and final
percentage of salt in brine used for investigation was 2.57%. Cabbage
samples were taken after 0, 3, 6, 12, 24 days and at the end of fermentation
process (44th day for one group of samples and 55th day for the other) in
order to determine total color and texture changes. Temperature and pH value
were analyzed during the fermentation process, while water activity (aw) and
total sugars content were analyzed for raw cabbage samples and on the last
fermentation day. 44th day was determined as the end of fermentation for six
samples, and 55th day for three samples, by measuring remaining sugar
content. Considering into account all obtained results and fermentation
conditions, sample 9F shown the best properties at the last fermentation day
in terms of investigated physico-chemical parameters. aw value, shear force,
total color change, pH value and total sugar content of this sample on the
last fermentation day were 0.958, 14672 g, 8.46, 3.45 and 0.92%,
respectively.
