After several weeks of fermentation of the sweetened tea in an open vessel, the resulting kombucha beverage is acidic/sour, yet somewhat sweet, and slightly carbonated 2. Various species of acetic acid bacteria present in the culture utilize glucose as a building block to synthesize cellulose which forms a thick, rubbery mat on the surface of the liquid 1- 3. Glucose and fructose are converted to carbon dioxide and various organic acids, the most prevalent being acetic and gluconic acids 1, 2. The microorganisms ferment the sucrose under aerobic conditions, the first step being the breakdown of sucrose into glucose and fructose by the yeast enzyme invertase 1, 2. It is produced by the action of a symbiotic culture of bacteria and yeast on sucrose-sweetened tea (black or green). Kombucha is a nonalcoholic or low-alcoholic fermented beverage (<0.5% alcohol by volume) that has been prepared for centuries in China, Russia, and Germany and used as a tonic drink or for medicinal purposes 1. The exercises have been used with positive results for several semesters in mid-sized laboratory sections (10–16 students) of the junior/senior biochemistry laboratory course at Indiana State University. Each of the three exercises can be completed in a typical laboratory session lasting two to three hours.

With this in mind, we have designed a series of three laboratory exercises with the common theme of analyzing the changes in sugar content in kombucha during fermentation of this increasingly popular beverage. In this situation, students become more familiar and comfortable with the system being studied and can delve more deeply into the theory behind the exercises. A carefully chosen theme can help to capture students' attention, motivate them to study the topic in depth, and provide continuity over a portion of the course.

Interested in trying kombucha? It’s important to only buy it from a trusted source, says registered dietitian nutritionist Beth Warren, author of Living a Real Life with Real Food. “Because it is raw, it is not pasturized,” she tells Yahoo Health. Moskovitz says you can also get a lot of the same perks of kombucha from other fermented foods such as kefir, kimchi, and miso paste, as well as B vitamins found in the drink from seeds, nuts, and lean meats. Sure, kombucha offers up probiotics (an eight-ounce bottle of Synergy Kombucha has approximately two billion probiotic organisms), but Cording says you can still get those probiotics from yogurt - and will also get calcium and vitamin D in the process.

While kombucha has some known benefits, Moskovitz points out that it isn’t for everyone. “We really don’t know that drinking a supplement is better than eating the whole food that those antioxidants will be found in like berries, green tea, and citrus fruits,” she tells Yahoo Health. However, she says it’s important to consider the source of the information - kombucha brands themselves.
Kombucha may also have some antioxidant benefits, says New York City registered dietitian Jessica Cording.
“It contains energizing B-vitamins and is a good source of healthy probiotics that aid in digestion and have been linked to strengthening the immune system,” she tells Yahoo Health. A lot of the claims surrounding kombucha are overstated, but it does have some health benefits, says Lisa Moskovitz, RD, founder of New York Nutrition Group.
