Abstract
In recent years, sports drinks continue to be pursued and admired by sports groups, especially sports enthusiasts. It can be said that as long as there is a drinks area, it will exist. Because of the vigorous development of sports drinks market, some unscrupulous businessmen, in order to seize the market, reduce costs, and seek huge profits, illegally addsynthetic colorants to the products to replace the natural colorants. In contrast to the various illegally added substances suitable for drinks, it is found that acid dyes,this kind of synthetic pigment can effectively reduce the production cost in the production, and the production process relative to the natural edible pigment is short in cycle, high in efficiency, and low in price, thus easy to be used by unscrupulous businessmen. In this paper, the detection of the most common illegally added substances - synthetic colorants in sports drinks is studied. It establishes ultra performance liquid chromatography (UPLC) method for rapid detection of colour agent in the sports drink. The method is sensitive, efficient and good in separation effect, which can be used in routine testing for a variety of synthetic colorants - acidic industrial dyes in sports drinks.
