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.

Sugars can affect our blood glucose (sugar), weight and blood fats. Synthetic sugars (artificial sweetener) provide little or no calories or carbohydrate or do not increase blood sugar. In food and pharmaceutical industries, blends of sweeteners are commonly used to design the food products and pharmaceutical doses, the information regarding type and extent of sweetener-sweetener and sweetener -water interactions and taste quality of the solution required. The aqueous solutions of arabinose, xylose and galactose with and without cyclamate are studied. Densities of solutions of arabinose, xylose and galactose in presence of 0.05, 0.15 and 0.3 m sodium cyclamate have been measured at 298.15K. Partial molar volumes, apparent specific volumes, partial molar volumes of transfer and doublet and triplet interaction parameters have been calculated. The information obtained from these parameters has been used to understand type and extent of sweetener-sweetener and sweetener -water interactions and taste quality of the solution.

Specific Volumes

Densities of sodium cyclamate (Na-cycl) in water and (0.1, 0.3, and 0.5)m(glucose/sucrose) have been measured at (298.15, 303.15, 308.15, and 313.15) K. From density values, partial molar volumes (V0Φ), expansion coefficient (E∞), Hepler’s constant (δ2V0Φ/δT2)p, apparent specific volumes (ASV), partial molar volumes of transfer (∆trsV0Φ), doublet (VAB) and triplet (VABB) interaction coefficients have been calculated. An increase in the values ofV0Φand ∆trsV0Φwas observed with increase in the concentration of glucose/sucrose. The positive values ofE∞ andV0Φare due to the strong solute-solvent interactions. The positive values of (δ2V0Φ/δT2)psuggest structure making behaviour of sodium cyclamate in water and in presence of glucose and sucrose. The positive values of (∆trsV0Φ) andVABmay be due to the interactions between hydrophilic group (–OH, C=O, and –O–) of glucose/sucrose and sodium ion of sodium cyclamate. All solutions studied exhibit sweet taste because ASV of all solutions ranges from (0.569 × 10-6) m3×kg-1to (0.626 × 10-6) m3×kg-1.

Experimental Values

Two methods are given for assessment of density of binary aqueous solutions of electrolytes; one is based on partial molar volume of the dissolved electrolyte at infinite dilution, and the other is based on additivity of apparent molar volumes at a given concentration. The density estimates of aqueous solutions by means of the two methods are compared with experimental values for some electrolytes of the type 1-1 to 4 and 2-2. In all cases the estimates agree with experimental densities up to concentrations of the saturated solutions.
