Abstract

In order to establish the quality standards of the cocoa butter produced in Brazil the following deterrninations were made: acíd value, index of refraction, iodine absorption number, melting point, moísture and volatile matters, and unsaponifiable residues. The composition of the fatty acíds was also deterrnined, An adapta-
tion to the process of methylation through transesterification with sodíum methylate was made too. iMiethylic esters were analysed by gas-liquid chromatography with a flame ionization detector.
The follawing acíds were identified and determined: lauric, myristic palmitic, palmitoleic, estearic, oleic, linoleic, arachídíc, linolenic and behenic acids. Furtherrnore, another saturated fatty acid with 17 carbon atoms was also detected,
