Key Points:
- Researchers from Wrocław University studied how different tea varieties (black, green, white, oolong, pu-erh) affect kombucha’s chemistry, flavor, and antioxidant potential, finding significant differences in fermentation outcomes.
- The type of tea influences fermentation dynamics and final kombucha composition due to varying levels of polyphenols, catechins, caffeine, and other bioactive compounds metabolized by the SCOBY culture.
- Kombuchas made from green and oolong teas exhibited the strongest antioxidant activity and highest ability to neutralize free radicals, suggesting greater biological potential compared to other teas.
- Fermentation transforms tea’s bioactive compounds and volatile aromatic substances, creating distinct flavor and aroma profiles; green tea kombucha had fresher, vegetal notes, while oolong had floral and fruity aromas.
- Although laboratory results are promising, researchers emphasize the need for further clinical studies to confirm kombucha’s health benefits in humans.
