Possible Interaction: Potassium Chloride and Trehalose

“Though KCl was previously shown to increase the chemical activity of trehalose but not of sucrose, we found that it suppressed the perceived sweetness of both sugars.”

“Moreover, in contrast to their action on other known carbohydrates, both KCl and NaCl act as salting-out agents towards trehalose , as seen in the elevated activity coefficient compared with its value in pure water (up to ∼1.5 higher at low sugar and salt concentrations).”

“Remarkably, especially at low salt concentrations, trehalose considerably elevates the activity (or chemical potential) of KCl , raising the salt activity coefficient as high as ∼1.5 its value in the absence of the sugar.”

“Using a modified isopiestic methodology that relies on contemporary vapor pressure osmometry, we elucidate how trehalose modifies the thermodynamic chemical activity of sodium and potassium chloride , as well as the effect of the salts on the sugar's activity.”
