Commercial samples of Malaysian cocoa butter (MCB), anhydrous milkfat (AMF), high melting fraction milkfat42 (HMF42) and cocoa butter equivalent (CBE) were blended in binary and ternary blends. All the fats were then evaluated for their solid fat content, thermal analyses and polymorphic stability. MCB possessed the highest solid followed by CBE, HMF42 and AMF. Data on thermal analyses showed that eutectic interaction was more noticeable when AMF and HMF42 were present in the MCB and CBE system. Moreover, X-ray diffraction patterns also showed that AMF and HMF42 exhibit the presence of beta' polymorph while MCB and CBE exhibit beta polymorph. [ABSTRACT FROM AUTHOR]
