Polydextrose 503<br />

at 25°C. Polydextrose acts in a similar manner to sucrose in that it results in a<br />

clear solution without haze or turbidity. Good mechanical mixing is required to<br />

prepare concentrated solutions. The rate of solubility will depend on the efficiency<br />

of the mixing equipment as determined by shear speed and rate of addition.<br />

Use of moderate heat and slow rate of addition aid in making these solutions. A<br />

preblend with another water-soluble ingredient is another technique that will<br />

greatly speed the rate of solution of polydextrose.<br />

C. Viscosity<br />

The viscosity that polydextrose contributes to a solution is greater than that contributed<br />

by an equal amount of sucrose. Figure 2 illustrates the viscosity of 70%<br />

solutions of polydextrose, sucrose, and sorbitol at varying temperatures. In a manner<br />

similar to sucrose solutions, the viscosity of polydextrose solutions decreases<br />

with an increase in temperature.<br />

The viscosity-enhancing effect of polydextrose plays an important role in<br />

food uses such as reduced-calorie dressings and puddings. Figure 3 shows the<br />

Figure 2 Temperature/viscosity relationships for 70% solutions.
