Density study of (D (+) mannose + water), (D (+) mannose + water + sodium cyclamate), (D (+) maltose monohydrate + water) and (D (+) maltose monohydrate + water + sodium cyclamate) systems at T = 298.15 K

Abstract

Effect of different concentrations of aqueous solutions of sodium cyclamate on sugars (mono and disaccharides) are observed by measuring the densities of (sugar + water) and (sugar + water + sodium cyclamate) systems. Densities of aqueous solutions of D (+) mannose (monosaccharide) and D (+) maltose monohydrate (disaccharide) in (0.05, 0.15, 0.3) mol.kg-1 of sodium cyclamate (Na-Cyclamate) at T = 298.15 K have been measured. From experimental values of densities , Vɸ0( partial molar volumes) ΔtrsVɸ0 (partial molar volumes of transfer) ASV (apparent specific volumes) interaction parameters (𝑉𝐴𝐵) and (𝑉𝐴𝐵𝐵 ) have been determined. The calculated values of various parameters have been used to interpret the results in terms of (D (+) mannose – water), (D (+) mannose –water– Na-cyclamate), (D (+) maltose monohydrate – water) and (D (+) maltose monohydrate – water – Na-cyclamate) interactions in sugar– water – Na-cyclamate and quality of taste sense of solutions.
