The samples were whole bananas (Musa spp. nanica (AAA)),
with the same degree of maturity, produced in Alagoa Nova city,
Paraíba, Brazil; damaged fruits were discarded. Drying was performed
in a convective dryer with vertical air flux, developed in
Federal University of Campina Grande. Four experiments were carried
out at drying air temperature of about 70 C, being the average
air velocity of 0.55 m s1, with average room temperature about
30 C. In the first experiment, continuous drying was carried out,
using only one banana placed at a sieve on the dryer as is shown
in Fig. 1.
