Hypothesis
How do the interactions between Saccharomyces cerevisiae and Pichia kudriavzevii affect the flavor profile of kiwifruit wine?
Conclusion
Mixed fermentation with Saccharomyces cerevisiae and Pichia kudriavzevii enhances the flavor profile of kiwifruit wine by increasing certain esters and volatile acids while decreasing others.
Supporting Evidence
- Mixed fermentation increased the levels of fruity and floral aromas in kiwifruit wine.
- Transcriptomic analysis revealed significant changes in gene expression related to flavor compound production.
- Specific genes were identified as crucial for the biosynthesis of esters and volatile acids.
Takeaway
This study shows that mixing two types of yeast can make kiwifruit wine taste better by changing the flavors that come out during fermentation.
Methodology
The study involved monoculture and mixed culture fermentation of two yeast species, analyzing biomass, flavor profiles, and transcriptomic responses.
