The effect of banana on sluggish fermentation
The effect of banana additions on ethanol production in blueberry
wines after 20 days of fermentation is shown in Fig. 5. The
levels of ethanol in wines containing 2%, 4% and 6% of banana were
1.32e1.68 times higher than that of the control. Residual sugar in
musts was decreased and ethanol production was increased in
proportion to the amount of banana added. These data suggest that
the likelihood of stuck and sluggish fermentation in blueberry wine
could be improved by the addition of banana. Although the ethanol
concentrations increased in proportion to the amount of banana
added before fermentation, the slope decreased. Different amounts
of banana could be used as a nutritional supplement for yeast to
solve stuck and sluggish blueberry wine fermentation.
