Unripe banana has been considered an ideal product for
industrialization, in addition to its high resistant starch content and
low soluble sugar concentrations (Cordenunsi and Lajolo, 1995). Its
flour may present (61.3e76.5) g/100 g of starch (d.b.); moreover
great part of the starch found in unripe banana flour is the resistant
starch type 2 (Faisant et al., 1995; Juarez-Garcia et al., 2006).
Resistant starch has attracted interest because of its positive effects
in the human colon and implications for health; it can be used as a
source of fiber, since it presents physiological effects that are
similar to those produced by the dietary fiber (Menezes et al., 2011).
However at temperatures above 60 C the gelatinization occurs and
the resistant starch becomes into digestible sugars.
