Kombucha is a fermented tea beverage that originated in ancient China over 2,000 years ago. It is made by fermenting sweetened tea with the help of a symbiotic culture of bacteria and yeast (SCOBY). The SCOBY consumes the sugar in the tea, producing a range of organic acids, vitamins, enzymes, and other beneficial compounds.
How is Kombucha Made?
The process of making kombucha involves several steps:
- Brewing the Tea: Kombucha is traditionally made with black or green tea, although other types of tea can also be used. The tea leaves are steeped in hot water, and sugar is added to provide a food source for the SCOBY.
- Adding the SCOBY: Once the tea has cooled, a SCOBY is added to the mixture. The SCOBY floats on the surface and initiates the fermentation process.
- Fermentation: The fermentation process typically takes around 7 to 14 days. During this time, the SCOBY metabolizes the sugar, converting it into various compounds. This process produces carbon dioxide, which gives kombucha its characteristic effervescence.
- Flavoring and Bottling: After the fermentation period, the kombucha can be flavored
Flavoring and Bottling:
After the fermentation period, the kombucha can be flavored with additional ingredients such as fruits, herbs, or spices to enhance its taste. Common flavor options include ginger, berries, citrus, and mint. The flavored kombucha is then bottled and sealed to allow for further carbonation.
Nutritional Profile of Kombucha:
Kombucha is a low-calorie beverage that offers a range of nutrients and bioactive compounds. The exact nutritional composition can vary depending on factors like the tea used, fermentation time, and added flavors. However, a typical serving of kombucha (approximately 8 ounces) may contain:
- Calories: 30-50 calories
- Carbohydrates: 7-10 grams
- Sugar: 2-4 grams
- B vitamins (such as B1, B2, B6, and B12)
- Organic acids (including acetic acid, lactic acid, and gluconic acid)
It’s important to note that the nutritional content can vary between brands and homemade brews. Additionally, flavored kombucha may contain additional sugars or additives, so it’s advisable to check the label for specific details.
Polyphenol Content in Tea:
The primary source of polyphenols in kombucha is the tea used during the brewing process. Both black and green tea contain a wide array of polyphenols, including flavonoids like catechins, epicatechins, and flavonols. These polyphenols contribute to the antioxidant and anti-inflammatory properties of both tea and kombucha.
The Fermentation Process and Polyphenols:
During kombucha fermentation, the SCOBY metabolizes the tea’s polyphenols, resulting in changes in their composition and concentration. The fermentation process can lead to the breakdown of larger polyphenols into smaller, more bioavailable compounds. This transformation may enhance the absorption and bioactivity of the polyphenols in kombucha.
Studies on Polyphenol Levels in Kombucha:
Several studies have examined the polyphenol content of kombucha and compared it to other beverages. While the results vary, research generally indicates that kombucha does contain polyphenols, albeit in varying concentrations.
