Piqui (caryocar Brasiliense Camb) Oil Triglyceride Composition Modification By Enzymatic Way [modificação Por Via Enzimática Da Composição Triglicerídica Do óleo De Piqui (caryocar Brasiliense Camb)]

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 70°C and substract weight ratio of 0,33 (stearic acid:piqui oil).2111619Stevenson, R.W., Luddy, F.E., Rothbart, H.L., (1979) J.
