【摘要】 本试验是以福州市售的康师傅、统一、娃哈哈与可口可乐以及其他品牌的茶饮料为试材,对不同品牌同一茶类、同一品牌不同茶类、同一品牌同一茶类在不同贮存时间下的茶饮料感官品质、生化成分与添加剂进行分析。研究结果如下:(1)通过对不同品牌同一茶类的茶饮料生化成分与添加剂分析,结果表明:不同品牌同一茶类的茶饮料在生化成分与添加剂上存在差别,大品牌企业生产的茶饮料品质生化成分稳定,添加剂使用量少,原料茶的功能性特征显著,中小品牌企业生产的茶饮料品质生化成分波动较大,添加剂使用量大,原料茶的功能性特征不显著,其检测结果都符合国家饮料标准的要求。(2)通过对同一品牌不同茶类的茶饮料生化成分与添加剂分析,结果表明:同一品牌不同茶类的茶饮料在生化成分与添加剂上存在差别,同一品牌企业生产的茶饮料以绿茶和红茶类饮料居多,且功能特征表现较之其他茶类显著,更受消费者青睐,其检测结果都符合国家饮料标准的要求。(3)通过对同一品牌同一茶类的茶饮料在不同贮存时间下的生化成分与添加剂分析,结果表明:不同贮存时间下的茶饮料在生化成分与添加剂上呈微量降低趋势,其检测结果都符合国家饮料标准的要求。(4)通过对不同品牌同一茶类、同一品牌不同茶类、同一品牌同一茶类在不同贮存时间下的茶饮料感官品质分析,结果表明:各品牌茶饮料感官品质各不相同,大品牌企业生产的茶饮料与中小品牌企业生产的茶饮料品质和生化成分波动显著,这是由于不同品牌各自生产的生产加工工艺与投入的资源所决定的。更多还原

【Abstract】 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.更多还原
