The production of mango powder by spray drying and cast-tape drying, with and without the addition of maltodextrinwas
investigated.Moisture, particle size distribution, bulk density, particle density, porosity,morphology,
total carotenoids content, water sorption isotherms, glass transition temperature and color of mango powders
fromboth drying processes were compared. Powders resulting fromcast-tape drying had irregular structure, different
from the spherical structures showed by powders produced by spray drying. Cast-tape drying process resulted
in powderswith bulk densities of 0.8 g cm−3 (with maltodextrin) and 0.7 g cm−3 (without maltodextrin),
higher than the observed for analogous powders produced by spray drying (bulk densities of 0.45 and 0.5 g
cm−3). Also, porosity of powders from cast-tape drying (below 60%) was lower than that of powders produced
by spray drying.Mango powders produced by spray drying without maltodextrin showed the highest carotenoid
concentration (113 μmof carotenoid g−1 of dry mass). The state diagrams show that mango powders produced
by spray drying exhibit slightly lower stability than those produced by cast-tape drying. Cast-tape drying is a suitable
procedure for the production ofmango powders and allows producing powders fromwhole fruit pulp,without
the addition of maltodextrin.
