Conteúdo: | Novel cocoa butter equivalents were designed using dry fractionated Pequi oiland solvent fractionated Kpangnan butter. Static crystallization of binary mix-tures into the triclinic form (β2) was achieved after 12 days of static crystalliza-tion at room temperature for all mixtures and after 4 days only for the 80:20w/w and 90:10 w/w fractionated Kpangnan: Pequi oil mixtures. However, after60 days of storage at 22C, all binary blends (except 100% fractionated pequioil and 100% fractionated Kpangnan butter) were crystallized in the most stabletriclinic crystal form (β1). Here we also reported a higher melting behavior forthe fractionated Pequi oil: fractionated Kpangnan (80:20 w/w and 90:10 w/w),after 4 days of static crystallization at room 22C, which, based on the x-rayresults, could be addressed to completion of crystal polymorphic transition tothe triclinic β2 form during 4 days of storage. Our results suggest that the 70:30w/w fractionated Pequi oil: Kpangnan mixture after 60 days of storage at 22Cshowed a melting point of 34C, a stable triclinic β2 form, and a triglyceridecomposition of 28% POP, 4.6% POS, and 33% SOS displayed solid-statecharacteristics, melting point, and crystal structure, of a novel cocoa butter equivalent.
