Modificação por via enzimática da composição triglicerídica do óleo de piqui (Caryocar brasiliense Camb) Piqui (Caryocar brasiliense Camb) oil triglyceride composition modification by enzymatic way

Abstract

Piqui (Caryocar brasiliense Camb) oil was transformed into a cocoa butter-like fat through an enzymatic interesterification reaction using Lipozyme in the presence of stearic acid that was incorporated in the sn 1,3-3,1 position into triglyceride. Stearic acid incorporation was determined by HPLC, based on the quantification of the principal triglycerides (POP, POS e SOS) found in cocoa butter. The proposed process was feasible with a reaction time of 240 minutes with 10% of Lipozyme at 70ºC and substract weight ratio of 0,33 (stearic acid:piqui oil).
