title: Soluble sugars in soft drinks.
abstract: The qualitative quantitative composition of soluble carbohydrates have been determined in 16 frequently consumed soft drinks. The qualitative analysis was carried out by thin layer chromatography. The quantitative determination was done by column chromatography and spectrophotometric technique. Most of the soft drinks analyzed contain the monosaccharides glucose and fructose and the disaccharide sucrose. For some of the drinks, the amounts of these sugars vary from bottle to bottle of the same soft drink. This is probably due to a hydrolytic process of sucrose taking place during storage as a result of the acidic pH of the media. The content of total soluble carbohydrates of most of the drinks analyzed is rather high and may represent an important caloric supplement in the diet, considering the high consumption of these drinks by the Spanish population.
