In early 2008, Coca-Cola launched a new sugar-free soda drink, ZERO, in Shanghai. The ingredients of ZERO Coca-Cola generally include carbonated water, aspartame, color, phosphoric acid, sodium citrate, sodium benzoate, flavor and caffeine. In the mainland China formula, there is also sucralose and no white sugar. This contains a little bit of calories from the aspartame, but the amount is very low, so the calories in the whole drink are negligible.

Aspartame is a common food additive. But with claims of aspartame causing cancer in Britain and Italy in recent years, the additive has become controversial. Coca-Cola's "Zero Degree" also inevitably encountered a war of words. Aspartame can be found in beverages, cereals, and food products such as chocolate and chewing gum, but not all products that use aspartame are questionable. Again, aspartame isn't the only additive that has brought Coca-Cola into disrepute in the same way. As Coca-Cola's staple carbonated beverage has gained popularity around the globe, there have been waves of skepticism. Undoubtedly, the growth of the market harvest is directly proportional to the responsibility that needs to be borne. Previously, Wang Hai, the domestic "superhero of counterfeiting", sued Coca-Cola's bottling plant in court for failing to clearly label its caffeine content. Another expert pointed out that carbonic acid may also lead to osteoporosis.

In the face of all the skepticism, Coca-Cola, on the one hand, has always insisted on the safety of its products, while on the other hand, it has spent a lot of money on aggressive marketing. But Coca-Cola, and its rival PepsiCo, have not completely ignored the potential threat posed by the health concerns.

In fact, both Coca-Cola and Pepsi have been active in the non-carbonated beverage sector in recent years, and both are seeking to redeem themselves from the carbonated beverages that are the foundation of the two companies. Sugar-free cola may be the direction that both sides coincide with. 2008 Coca-Cola "zero degree" in the domestic first battle after the success, PepsiCo in 2009 quickly its similar products "extreme" in the national market spread. In addition, the two music juice products of the United States Juyuan and pure fruit music this summer's encounter is also particularly fierce.
