Correlation of protein content to flatulent galactooligosaccharides and exogenous amino acids in seeds of Phaseolus vulgaris L.

Ryszard Kosson


In order to estimate the possible correlations among constituents of Phaseolus vulgaris seeds, the contents of protein, exogenous amino acids and flatulent galactooligosaccharides (raffinose and stachyose) were analyzed in 16 Polish bean cultivars for dry seeds. A negative correlation coefficient (r =-0.9490) was found between protein and methionine contents. High positive correlations among exogenous amino acids, such as lysine and isoleucine, valine and isoleucine, lysine and tyrosine, were observed indicating a chance of selecting far more than one at a time. The small-seeded bean cultivars contained higher contents of protein and galactooligosaccharides than the large-seeded ones.
