The most common
approach to dry such products has been to add high
molecular weight additives. This has the eect of raising
Tg. However, few attempts have been made to develop a
direct relationship between Tg and stickiness in a spray
drying process. In a recent report, Busin et al. (1996)
studied the role of Tg on the stickiness behaviour of the
maltodextrin-sugar (fructose, glucose, and sucrose)
mixtures during spray drying.
