Kombucha’s tea type alters flavor, chemistry, and antioxidant activity, study finds
6 reported
Scientists from Wrocław University of Environmental and Life Sciences and Wroclaw Medical University found that the type of tea used to make kombucha significantly affects its flavor, chemical composition, and biological activity. The study, published in the journal Food Chemistry, compared kombuchas made from black, green, white, oolong, and pu-erh teas. Researchers observed that fermentation transformed each tea into a distinctly different beverage, with green and oolong tea kombuchas showing the highest antioxidant activity and capacity to neutralize free radicals. The team used advanced chromatographic methods and mass spectrometry to track hundreds of chemical compounds. They cautioned that these laboratory findings do not prove specific health benefits in people and that further clinical studies are needed.
