Sucralose 193

is freely soluble in water and ethanol. As the temperature increases, so does the
solubility of sucralose in each of the solvents.
The solubility of sucralose in water ranges from 28.3 g/100 ml at 20°C to
66 g/100 ml at 60°C. The solubility of sucralose in ethanol was found to range
from 9.5 g/100 ml at 20°C to 18.9 g/100 ml at 60°C. These data demonstrate
that sucralose will be easy to use in food operations and that special techniques
or equipment to solubilize the sweetener are unnecessary (11).
C. Dynamic Viscosities
The dynamic viscosities of aqueous sucralose solutions were measured from 20°C
to 60°C and from 10–50% w/w concentrations within the solubility range. A
Rheomat 30 viscometer was used and was fitted with a concentric cylinder head
suitable for solutions of low viscosity. The dynamic viscosities of distilled water
and 10% w/w aqueous sucralose solutions at different shear rates are shown in
Fig. 5. Variations in viscosity over the four shear rates of 512, 691, 939, and
1280 sec 1 were insignificant, demonstrating that the sucralose solutions are Newtonian
in behavior. Dynamic viscosities of aqueous sucralose solutions measured
at 939 sec 1 are shown in Fig. 6. Comparison of these data with available data
for the viscosity of sucrose solutions shows that sucralose and sucrose have very
similar viscosities.
