Resumo
The cerrado is configured with one of largest biomes in terms of
representativeness and diversity in Brazilian territory. A wide variety of fruits
and that presents applicability in different areas, as agriculture and medicine,
can be found. Among these, the guapeva presents a large potential due to
sweet taste, nutritional and bioactive, and applications in medicine field.
Despite these characteristics, few studies considering this fruit can be found in
the literature. In this contribution, this work aims to contribute in study of
guapeva in terms of drying operation and characterization of produced flour
with the bark of this fruit. For this purpose, a tunnel type dryer, in which
experiments are performed to determine the parameters associated with the
guapeva drying kinetic and parameters associated with the phenomenological
model (effective moisture diffusivity and effective thermal conductivity). In
this case, two inverse problems were proposed and solved by using the
Differential Evolution algorithm. From the results obtained it was possible to
observe a good concordance between the experimental and predicted results.
In relation to physical-chemical analysis of the flour produced, it was possible
to observe a good nutritional quality in comparison with other commercial
flours. In this context, the product resulting from the drying process is
configured as an alternative, from the nutritional point of view, to traditional
products found in market.
