5. Conclusion
This research is the first report to provide the effects of bananas on improving sluggish fermentation in blueberry wine. The present study revealed that early addition of yeast nutrients and bananas affects the evolution of yeast during fermentation. It was interesting to note that the residual sugar in musts decreased and ethanol production rate increased in proportion to the amount of banana added prior to fermentation. These data suggested that the likelihood of stuck and sluggish fermentation in blueberry wine can be improved by banana addition. This study further demonstrates the cause of the sluggish fermentation of blueberry wine and how bananas function in the evolution of yeast.
