Pracaxi Oil as a Potential Inhibitor of Fat Bloom

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Fat bloom is one of the major technological challenges faced by the chocolate industry, caused by the polymorphic transition from β2(V) to β1(VI) crystals in cocoa butter (CB). One strategy to slow down this polymorphic transition is the addition of lipids rich in very long chain fatty acids (VLCFA), such as behenic acid.
