Scientists studied how different teas affect kombucha's taste, smell, and health benefits. They found that tea type greatly impacts kombucha's properties.

The popularity of kombucha has grown worldwide, but researchers are now exploring what happens inside the drink during fermentation. A team from Wrocław University of Environmental and Life Sciences and Wroclaw Medical University investigated whether the type of tea used to make kombucha affects its final product. They compared kombuchas made from black, green, white, oolong, and pu-erh teas.

The researchers found that the type of tea acts as a matrix that shapes fermentation and the final composition of kombucha. This means that individual teas differ in their content of polyphenols, catechins, caffeine, and other bioactive compounds, which are then metabolized by SCOBY microorganisms.

During fermentation, yeasts convert sugars into alcohol and carbon dioxide, while bacteria transform those compounds into organic acids, primarily acetic acid and gluconic acid. These acids give kombucha its familiar tart flavor. The process also alters many of the tea's naturally occurring compounds.

The team discovered that kombuchas made from different teas can vary in their biological properties. Green and oolong kombuchas showed the highest antioxidant activity, which is important because antioxidants help neutralize free radicals that can damage cells and contribute to aging.

Why It Matters

This research matters because it shows how something as simple as tea type can impact the health benefits of kombucha. As students in India, you may be interested in learning more about the potential health benefits of fermented foods like kombucha.
