actually no fungus involved in the fermentation. This beverage reportedly exerts a number
of medicinal effects against metabolic disease, arthritis, psoriasis, constipation, indigestion,
and hypertension. By virtue of the numerous health-promoting aspects reported and the
easy and safe preparation of this beverage at home, it has gained popularity as other traditional
beverages. Tea fungus is a symbiotic growth of acetic bacteria and yeast strains
cultured in sugared black or green tea (1). The fermentation is traditionally carried out by ino-

culating a previously grown culture into a freshly prepared tea decoction and incubated
statically under aerobic conditions for 7-10 days (2).
In the past few years, there has been a growing interest in the use of natural additives
in preference to synthetic substances for the stabilization of foods. Because some synthetic
antioxidants, such as butylated hydroxyanisole and butylated hydroxytoluene, have been
implicated in acute toxicity and chronic diseases in experimental animals, various plant
extracts have gained attention as sources of safe antioxidants. The natural antioxidants in
herbs, spices, and teas have been extensively studied (3).
Dietary factors play a major role in chronic diseases development. A number of these
chronic diseases, cardiovascular diseases and cancer, have been linked to excess production
of reactive oxygen species and oxidative damage to biomolecules. Derived from
plant material and containing numerous biologically active compounds, tea beverage
