Abstract
Functional properties of the Great Northern bean (Phaseolus vulgaris L.) flour, albumins, globulins, protein concentrates, and protein isolates were investigated. Protein concentrates had the highest water and oil absorption capacity (5.93 and 4.12 g/g, respectively) among all the samples studied. Protein concentrates registered the highest emulsion capacity (72.6g oil emulsified/g) while albumins had the highest emulsion stability (less than 5 ml separation of phase in 780 hr at room temperature of 21°C). Foaming ability of the Great Northern bean proteins was fair. Foamability of the proteins was concentration dependent.
