Abstract The analysis was carried out using X-Ray diffraction1–3 (XPertPro Panalytical) of polymorphic forms of Milk chocolate, Dark Chocolate and pure Cocoa Butter samples. Sugar was removed from the samples as sucrose signals interfere with those of cocoa butter. The XRD patterns obtained for the Milk Chocolate and Dark chocolate were compared to that of the pure cocoa butter. Strong peaks were observed at 4.16Å (Form I), 4.24Å (Form II), 4.24Å (Form III), 4.38Å (Form IV) and 4.56Å (Form V), which can be used to infer the various crystal structures of the polymorphs of cocoa butter.
