The perceived effect of adding salts on the sweetness of bulk sweeteners (s
ucrose, glucose, fructose, sorbitol and xylitol) depends on the sweetener t
ype and concentration and on the type of salt. Sodium chloride enhances the
sweetness of all the sweeteners to some degree. Potassium chloride has lit
tle effect on any sweetener other than sorbitol, which shows sweetness enha
ncement at low sorbitol concentrations and suppression at high sorbitol con
centrations. Magnesium chloride additions tend to enhance sweetness, partic
ularly of sucrose and glucose. The effects observed can not be ascribed to
any inherent sweetness of the sails themselves, suggesting that the observe
d effects are a result of interactions between the salts and sweeteners in
the aqueous medium. (C) 2000 Elsevier Science Ltd. All rights reserved.
