Measuring Ethanol in Kombucha Tea by HS-SPME

Webinar

In this webinar, we discuss method development and validation for measuring the ethanol concentration in kombucha tea with solid phase microextraction (SPME).

Kombucha, A fermented tea beverage produced by the addition of a mixture of yeast and acetic acid bacteria to a solution of sugar and tea, is an effervescent solution containing phenolics, water soluble vitamins, organic acids and some ethanol. Ethanol testing in kombucha is important to ensure the alcohol content is <0.5% in the United States and avoid being regulated as an alcoholic beverage. Listen to our 15-minute talk to learn about developing an SPME (Solid Phase MicroExtraction) method for alcohol in Kombucha, the method validation and testing of commercial samples.
