Tea is amongst one of the most widely consumed beverages inside the globe, subsequent only to water and well ahead of coffee, beer, wine and carbonated soft drinks [3]. It could be categorized into three kinds, based on the level of fermentation, i.e. green (unfermented), oolong (partially fermented) and black (fermented) tea. The term fermentation is typically made use of incorrectly in tea processing. The far much more appropriate term must be oxidation, which imply sexposure to air whilst drying without having any additives throughout the method. A further form of tea is white tea which may be developed from new growth buds and young leaves which have been steamed to inactivate polyphenol oxidation right after which dried. The buds may possibly be shielded from sunlight to quit formation of chlorophyll. With the , two.5 million metric tons of dried tea manufactured, only 20% is green tea and considerably less than 2% is oolong tea.
