Abstract

MARRUGO-LIGARDO, Yesid A; MONTERO-CASTILLO, Piedad M  and  DURAN-LENGUA, Marlene. Nutritional Evaluation of Concentrated Protein of Phaseolus lunatus and Vigna unguiculata. Inf. tecnol. [online]. 2016, vol.27, n.6, pp.107-114. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642016000600011.

The objective of this study was the evaluation of the nutritional potential of protein concentrates of Phaseolus lunatus and Vigna unguiculata. To do this, the amino acid composition, proximate composition and in vitro digestibility were determined. The results showed that although the amino acid composition determined by HPLC was higher in the protein concentrates of Vigna unguiculata; Phaseolus lunatus concentrate presented slightly superior nutritional properties, with a value of protein according to AOAC of 66.8%; a corrected chemical score (PDCAAS) according to FAO / WHO of 50.35; and a coefficient of digestibility of 83,93%; while the values of protein concentrates of Vigna unguiculata, were 65.29% for protein; 41.0 for PDCAAS and 82.11 for the digestibility coefficient. It is concluded that although significant differences in the evaluated characteristics of protein concentrates were not found, Phaseolus lunatus concentrate showed slightly higher nutritional characteristics.

Keywords : protein concentrates; nutritional potential; protein quality; digestibility in vitro.
