The seeds of leguminous plants, among which kidney bean Phaseolus vulgaris L. is classified, are very valuable food ingredients owing to their high contents of, among other things, protein, vitamins of the ‘B’ group, dietary fibre, and mineral compounds. The chemical composition of seeds fluctuates both quantitatively and qualitatively, and it depends on many factors, inter alia, on cultivar and maturity stage, environment, mainly weather conditions, agricultural science, and on other things. The objective of the study was to determine the content of some selected chemical compounds contained in dry seeds of five new cultivars of dwarf kidney bean (French bean) (Phaseolus vulgaris L.) The content of the following compounds was determined: total protein, fat, dietary fibre, starch, carbohydrates after inversion, and ash. The content of crude protein in dry matter of bean cultivar seeds investigated ranged from 23,96 to 29,85 g/100 g d.b. The content of fat in all the cultivars was similar and amounted between 1,54 and 1,78 g/100 g d.b. The seeds of the bean cultivars under investigation contained 20,66 g/100 g to 24,69 g/100 g d.b. of the total dietary fibre (TDF), 5,92 to 9,98 g/100 g d.b. of its soluble fraction (SDF), and 11,28 to 17,29 g/100 g d.b of its insoluble fraction (IDF). The content of mineral compounds determined as total ash ranged from 3,7 to 4,2 g/100 g d.b., and the content of carbohydrates after inversion: from 5,17 to 6,58 g/100 g d.b.
