This study used Kangshifu, unified, Wahaha and Coca Cola and other brands of tea beverages as test materials. The tea sensory quality, biochemical composition and additives were analysed in the different brands, kinds and storage times of tea beverages. The results are as follows:(1) Analysing different brands of the same kind of tea drinks in biochemical components and additives, results showed that: different brands of the same kind of tea tea beverage in the biochemical constituents and additives are different, Brand enterprises in the production of tea biochemical components and quality of stability, additives, raw tea functional characteristics significantly, small and medium-sized brand enterprises in the production of tea biochemical components and quality of volatile additives, the use of a large quantity of raw tea, functional characteristics are not significant, the results are in line with national beverage standards.(2) Analysing the same brand of different tea kinds in biochemical components and additives analysis, results showed that: the same brand of different tea kinds of tea drinks in the biochemical constituents and additives are different, The same brand enterprises in the production of tea drinks to green tea and black tea drinks are, and functional features than other tea significantly, more favored by consumers,the results are in line with national beverage standards.(3) Analysing the same brand of the same kind of tea drinks in different storage time of biochemical composition and additive analysis, results showed that: different storage time of tea drinks in biochemical components and additives on a trace decreased, the test results are in line with national beverage standards.(4) Analysing different brands of the same kind of tea, the same brand of different tea kinds, the same brand of the same kind of tea in different storage time of tea beverage quality analysis, the results show that: the brand of tea beverage quality varies, Brand enterprises in the production of tea beverages and small and medium-sized brand enterprises in the production of tea beverage quality and biochemical composition fluctuations significantly, this is due to the different brand of their respective production processing technology and resources devoted to the decision.
