Sugar and salt are commonly used in sports beverages, but the effect of these ingredients on turbidity of heat treated beverages that contain whey proteins has not been investigated. Sugars and sugar alcohols stabilized and prevented aggregation in several proteins including lysozyme, bovine serum albumin and BLG. Simple sugars and polyols are stabilized co-solvents, which are thought to be sterically excluded from the denatured state or accumulated in the native state. Decreased protein aggregation has also been attributed to an increase in surface area of the denatured state and the increase in surface tension caused by sugar addition that stabilizes the native state. Different salts can either increase or decrease the temperature at which proteins are denatured. Sports beverages currently contain both sugars and salts, and the effect of these ingredients on turbidity must be understood to successfully develop clear, heat-treated beverages that contain whey protein.
