Moisture and resistant starch contents of green banana flour
produced at each drying condition are presented in Table 2. The
maximum air temperature (58 C) was chosen in order to avoid the
green banana starch gelatinization. ANOVA applied on results
indicated that resistant starch content were influenced by the
combination of drying conditions (P < 0.05) and it can be observed
that at the same temperature of 55 C, lower air velocity decreases
the resistant starch content, probably due to the higher drying time
and consequently partial disorganization of the crystalline structure
of starch. However, with the same air velocity (0.6 m s1), the
flour presented similar resistant starch content when increasing
the temperature. At the conditions of lower temperature and lower
air velocity (52 C, 0.6 m s1), it was necessary to expose the
banana slices for a longer time in order to reach the equilibrium
humidity, diminishing the resistant starch content.
