Single-frequency dielectric relaxation used to characterize the glass transition time of polydextrose

Dielectric relaxation methods are applicable to powdery materials such as carbohydrates. These materials have relaxations that occur in the milli-Hz range while samples are held at fixed temperatures and fixed water activities, aw, (relativity humidity). Under proper conditions these materials under...
