Abstract :
This paper deals with the physicochemical characterization, including thermal behaviour, by differential scanning calorimetry of
mango seed almond fat (MAF), alone and in mixtures with cocoa butter (CB). Results showed that mango almond seeds contain
about 5.28–11.26% (dw) of fat. The refraction index is 1.466, the saponification index 189.0 and the iodine index 41.76. Fatty acids
found in MAF are oleic, stearic, and palmitic acids (40.81%, 39.07% and 9.29% (w/w), respectively) as well as smaller amounts of
linoleic, with arachidic, behenic, lignoceric, and linolenic acids, among others. Calorimetric analysis showed that MAF crystallizes
between 14.6 and )24.27 C with a DHc of 56.06 J/g and melts between )17.1 and 53.8 C, with fusion maxima at 18.54 C and
40.0 C for the a and b polymorphic forms. Their fusion enthalpies are 70.12 and 115.7 J/g. The MAF solids content profile is very
similar to that of CB, both in stabilized and non-stabilized samples. The mixing compatibility was analyzed using isosolids curves of
mixtures of different compositions.
