Based on Fig. 3, the melting point of binary mixtures containing 30%
and 80% fractionated pequi oil showed an disproportionate increase in
their melting point after four days of storage at room temperature. To
better understand this phenomenon, the ternary phase diagram of
POP+POS+SOS mixtures in meta-stable polymorphic form (pseudo-β’)
(Ghazani & Marangoni, 2021) was used to pinpoint the location of these
mixtures in the ternary plot (Fig. 4). The area with the symbols of *
and + show the location of mixtures containing 30% and 80%
fractionated pequi oil, respectively.
