The effect of germination (G; 5 days), soaking-cooking (SC; 6 h-20 min, 6 h-40 min, 6 h-60 min) and microwave (M; 50%, 70%, 100%) treatments on pigeon pea (PP), dolichos bean (DB) and jack bean (JB) seeds was studied. Microstructure of seeds and functional (protein solubility, water-holding capacity, oilholding capacity, emulsion stability) and pasting properties of flours were determined. Germination and microwave treatments modified the protein matrix of cotyledon cells preserving the shape of the starch granule, whereas the SC treatment (6 h-60 min) affected both. The soaking-cooking is the most influential treatment on the functional properties of PP, DB and JB flours, as increased water absorption capacity (73-96%), decreased protein solubility (>80%) and the tendency to retrogradation of amylose (69-85%) also improved emulsion stability.
