These authors also stated that the intensity values depend on the
storage RVP. Thus, in the present study, the intensity indicated that
the amount of crystal formation during storage at 68.9% RVP is
higher.
The XRD patterns of the sample at 68.9% RVP were compared to
sugar present in mangoes (glucose, fructose and sucrose), and subsequently
corresponded to the crystalline peak of the standard sucrose
(Fig. 3). This indicated that most of the crystalline regions in
freeze-dried mango powder consist of sucrose crystals, which is
the predominate sugar in mango. Moreover, the XRD patterns revealed
a curve at 10–30, which indicated the presence of some
amorphous regions in the samples which failed to crystallize, such
as soluble pectin.
