HERNANDEZ, Carlos; MIERES, Alberto; NINO, Zulay  y  PEREZ, Sergio. Effect of Physical Refining on the Oil of the Corozo’s Kernel (Acrocomia aculeata). Inf. tecnol. [online]. 2007, vol.18, n.5, pp.59-68. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642007000500008.

The principal objective was to evaluate the effect of the physical refining on the characteristics in the oil of the corozo’s palm kernel fruit (Acrocomia aculeata). The methodology, it began with a plan of sampling that allowed to obtain a representative sample of the fruit of the place of study. The oil was extracted using the operation of pressing in cold, then there was realized a physical refining that consisted of a degumming, bleaching, deodorized and desacidification. To the raw and refined oil there decided the profile of oily acids. In the stage of desacidification and deodorized the index of peroxide was of 1,974 miliequivalent of O2 kg-1 of oil. The degree of acidity determined as acid oleic for the raw and refined oil was of 0,620 and 0,100%, respectively. The physical refining applied reduced the smell and the degree of acidity of valuable form, being able to be recommended for the purification of this oil.

Palabras clave : Acrocomia aculeata; physical refining; corozo palm; oily acids; degree of acidity.
