Abstract

Proximal analysis, amino acid profile, trypsin inhibitor content, hemagglutinin content and HCN generated from cyanogenic glucosides were determined in four wild and three cultivated varieties ofPhaseolus lunatus. All the wild beans showed a higher protein content than the cultivated beans, but no big differences were found in the other nutrients. The essential amino acid percentage was higher in the cultivated beans than in the wild seeds, which was reflected in the PER determination. The most remarkable difference found between wild and cultivated beans was the high concentration of HCN in all wild varieties. The high concentration of protein found in the wild seed could be a false result from the nitrogen provided by the cyanogenic glucosides.
