Abstract. 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 suggest structure making behaviour of sodium cyclamate in water and in presence of glucose and sucrose. The positive values of (∆ trs V 0 ) and may 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 ) m 3 kg -1 to (0.626 10 -6 ) m 3 kg -1 .
