From the X-ray diffractograms in Fig. 4, the absence of peaks for
a short spacing of 4.6 Å and the presence of an intense peak showing
crystals with a short spacing of 4.2 Å can be seen for Po, where
crystals with a short spacing of 3.8 Å can also be observed. This
configuration characterises the absence of b-crystals and the strong presence of b0 crystals. In a similar way, Braipson-Danthine
and Gibon (2007) demonstrated the diffraction lines of the b0-form
for palm oil at 20 C, with peaks of low intensity suggesting short
spacings of 4.32 and 4.12 Å and peaks of high intensity in the short
spacings of 3.88 and 4.20 Å, close to those obtained in the present
paper.
