is decreased or by using gum Arabic, the particles tended to
become more spherical, more scattered. This can be explained
by the molecular structure of carrier agents. The average particle
size of powders ranges from 4 to 13 m (Table 2). Spray
dried black mulberry powders produced with maltodextrin
6DE has higher Tg point due to its larger molecule comparing
three other carriers (Table 2). The dextrose equivalency
of maltodextrin determines their reducing capacity and is
inversely related to their average molecular weight. Increase
in maltodextrin dextrose equivalent lead to lower powder Tg
