The Science of

Kombucha

Did you know?

The term "fermentation" originates from the Latin word "fervere," meaning "to boil." The ancient Romans, observing vats of grapes transforming into wine, linked the process to boiling, despite its inaccuracy. In scientific terms, fermentation involves yeast-produced enzymes transforming sugars into alcohol, a process observed in the transformation of grapes.

Probiotic Power: Kombucha, a probiotic beverage, contains living microorganisms that, upon consumption, colonise the gut, offering numerous health benefits. These microorganisms populate the gut with beneficial bacteria and B-vitamin-rich yeast, lower stomach pH, and kick-start digestion and nutrient absorption through healthy acids and enzymes. Acetic acid provides flavour and antimicrobial properties; gluconic, butyric, and lactic acids promote gut lining repair, balance pH, and combat Candida overgrowth. Enzymes like invertase and phytase break down complex sugars into simpler forms, easing digestion.

Immune-Boosting Effects: Kombucha's immune-boosting effects begin with its support for digestive function, thanks to its living organisms and healthy acids. Furthermore, Kombucha's antioxidant activity aids in neutralising free radicals, facilitating the breakdown of polyphenols and the production of essential compounds such as vitamin C and DSL (D-saccharic acid-1, 4-lactone).

Combating Bacteria: Kombucha exhibits significant activity against Gram Positive Bacteria and Gram Negative Bacteria. For example, Acetic Acid (5%) is known to reduce blood glucose, improve insulin sensitivity, lower weight/belly fat, triglycerides, and cholesterol. It also improves satiety and acts as a short-chain fatty acid, becoming food for beneficial gut bacteria. Glucuronic Acid (65%) assists in liver detox and hormone balance, while Gluconic acid (30%) supports the growth of Bifidobacteria and contains beneficial bacteria such as Bacillus Coagulans, S. Boulardii, and Lactobacillus B.

Fermentation is evolution in real time, and it’s a fascinating process in which to take part.
