PADILLA, Fanny C; LIENDO, Rigel  and  QUINTANA, Agricia. Characterization of cocoa butter extracted from hybrid cultivars of Theobroma cacao L. ALAN [online]. 2000, vol.50, n.2, pp.200-205. ISSN 0004-0622.

Cocoa butter is the most important fat used in the confectionery and chocolate industries. The main objective of the present study was to determine the physical and chemical characteristics of cocoa butter extracted from hybrid cultivars belonging to the germplasm bank of the Fondo Nacional de Investigaciones Agropecuarias (National Foundation for Agricultural Research). AOAC methods were used for the assesment ot the proximal composition of the beans, physical and chemical characteristics as well as for the fatty acid profile ofthe fat. It was found that there were statistical differences in the proximate composition of the cocoa beans among the cultivars studied as well as the iodine and saponification indices of the butter. Saturated fatty acids were present in higher proportions than unsaturated fatty acids, with palmitic and stearic acid as the main fractions. Oleic acid content was higher than linoleic acid. The fatty acid profile found is the main factor that influences the hard texture of the cocoa butter from Venezuelan cocoa hybrids cultivars.
