Seguimiento de volumetría, índice de deterioro a la blanqueabilidad (DOBI) y ácidos grasos libres (AGL) en el control de calidad de aceite de palma crudo (APC) en la planta extractora la Gloria S.A.S.

Abstract

The study focused on analyzing the quality of palm oil through two main parameters: the percentage of free fatty acids (%AGL) and the bleachability deterioration index (DOBI) at different stages of the process. Where some main values were found as the study of the fresh fruit, where an increase of 0.49% per day in FFA and DOBI decreasing on average of 0.27 units per day was observed. The best results were obtained in the first three days of fruit storage. Another factor was the analysis of the process streams, where the highest oil recoveries were obtained in digester liquor and press, higher than 60% oil. The critical quality points were in the sterilization condensates and rachis press, yielding poor DOBI and high acidity. The best DOBI was found in the digester liquor, due to the controlled treatment of temperature and maceration. Both digester, presses and centrifuges performed well in the quality parameters.
