Teabiochemistry is a subject of life science onCamellia Sinensis. It mainly focus oncharacteristic secondary metabolites of tea plants, especially those in the fresh tea shoots using biochemical and molecular techniques as researchtools. Those metabolites include catechins, caffeine, theanine and volatile terpenes, which contributegreatlyto tea quality and healthy effects.The major research fields of tea biochemistry involve the biosynthesis of secondary metabolites in tea plants, their transformation during tea processing and theireffects on final tea quality and healthy function. Recently,there have several breakthroughs in the metabolites biosynthesis pathway, tea genome, specific tea germplasm metabolome, theprocessingmetabolome, as well as the chemistry of tea quality. Since tea biochemistry is the fundamental in teascience, itsachievements provide the theoretical basis and method approaches to tea cultivation and breeding, tea primary and further processing, tea tradingand tea culture. With the development of tea industry and life science & technology, it isbelieved thattheadvancementof tea biochemistrywill push forward tea industry to a high level atthe sustainable development.
