Black And Green Tea Leaves And Extracts

Black and green tea leaves and extracts come from the leaves of the Camellia sinensis plant. The difference between black and green tea is how the leaves are processed after harvesting. Green tea is made from leaves that are steamed or pan-fired to prevent oxidation, while black tea is made from leaves that are allowed to fully oxidize.

Tea leaves and extracts are primarily used to provide flavor in beverages like iced tea, tea bags, and powdered drink mixes. They can also contribute to the color and perceived health benefits of these products.

Black and green tea are generally recognized as safe (GRAS) by the FDA for use in food. They contain compounds like flavonoids and caffeine, which have been studied for potential health effects. Regulatory bodies like EFSA have evaluated tea and its components. While often associated with health benefits, excessive caffeine intake can lead to side effects like jitters or sleep disturbances.
