Abstract

LAFONT, Jennifer J.; ESPITIA, Amelia A.  and  PAEZ, Manuel S.. Physicochemical Study of the Oil and Proximal Analysis of the Oilseed Cake Native to Córdoba-Colombia. Inf. tecnol. [online]. 2019, vol.30, n.4, pp.85-92. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642019000400085.

The objective of this work was to analyze the physicochemical properties of the oil, fatty acid profile and the proximal analysis of the cakes of three oilseeds: Thevetia peruviana (calabonga), Gossypium hirsutum L (cotton) and Enterolobium cyclocarpum (orejero). The seeds were harvested, their nuts were extracted and crushed to obtain the respective oil by the methods of pressing and solvent. The physicochemical properties were calculated following the method of the Association of Official Analytical Chemists (AOAC) and the fatty acid profile by gas chromatography/mass spectrometry (GC/MS). The residual cake from the pressing extraction was used for the proximal analysis. The results of the oil showed high content of unsaturated fatty acids (calabonga and cotton) classified as drying, unlike orejero with a higher proportion of saturated, non-drying. The proximal analysis of the three cakes, showed a high percentage of proteins, the cotton having a better nutritional content. According to the results, it was concluded that the seeds under study may have diverse applications in the industry.
