Conclusion
Kidney bean cultivars had significant differences in composition
and color values. Seed dimensions, sphericity, surface area,
bulk density and angle of repose were significantly different
among the cultivars indicating that these would require some
variation in the processing equipment design. Also difference
in 100-seed weight and 100-seed volume of the cultivars, suggests
that equal quantity of each cultivar would occupy unequal
space and the cost of packaging and transportation would be
different (if based on space occupied). Master Bean cultivar
had better cooking properties due to its shorter cooking time,
higher gruel solid loss and higher cooked length breadth ratio
than other cultivars. Textural properties like hardness, cohesiveness
and chewiness of cooked seeds did not show significant
differences among the cultivars, indicating that they have been
cooked to the same degree. Cooking time has significant
positive correlations with swelling capacity, porosity and fat
content. However, it has significant negative correlations with
cooked seed adhesiveness and cooked seed hardness.
