Abstract

SILVA JAIMES, Marcial Ibo et al. Effect of the debittered of moringa seed cake (Moringa oleifera) on its proximal composition and its nutritional and toxicological profile. Scientia Agropecuaria [online]. 2018, vol.9, n.2, pp.247-257. ISSN 2077-9917.  http://dx.doi.org/10.17268/sci.agropecu.2018.02.10.

With the purpose of evaluating the debittering of the seed cake of Moringa, they were pressed in order to obtain oil and cake. The cake was subjected to a treatment in saline solution (Cake SS) and ethanol (Cake OH) and its characteristics were compared with that of a Witness Cake. In each sample, in triplicate, the proximal analysis, the Biological Value, true digestibility, amino acid composition and the Amino Acid Score Corrected by Protein Digestibility (PDCAAS) were determined, as well as the tannins, saponins, phytates and cyanides. The content of protein in the Control Cake was 43.82%, in the SS Cake was 32.57% and in the OH Cake was 63.69%. The Biological Value of the Test Cake was 20.6; of the SS Cake was 24.3 and for the OH Cake was 56.9, demonstrating the advantage of the treatment with ethanol. Regarding the PDCAAS in the Testigo Cake scores of 115.46, 102.46, 142.79, 342.73, 125.71 and 110.00 for histidine, leucine, phenylalanine, threonine, tryptophan and valine, respectively, were higher compared to the debittered samples, however, the benefits of debittering, were observed in the elimination of 90% of tannins and 100% of phytates although the cyanides could not be removed.
