They used product recovery
as a measure of the ease of spray drying. Though
the powder recoveries were correlated to Tg in the case
of individual sugar-maltodextrin mixtures, there was no
consistency on recoveries between three sugar-maltodextrin
mixtures with the function of Tg. Bhandari et
al. (1997b) found a correlation between Tg and the spray
drying behaviour of sugars and fruit juices with a
maltodextrin additive (Fig. 3).
