SUMMARY:

The present study aims to obtain protein concentrates from cowpea and pigeon pea with and without prior immersion treatment, from the impact milling process followed by fractionation with dynamic aero classification. As a result of the fractionation process, two fractions are obtained, one rich in proteins called protein concentrate and another rich in starches and fibers. Both will be quantified and evaluated for their functionality considering the analyses of particle size distribution, paste viscosity, optical and electron microscopy, water and oil absorption, emulsifying capacity and foam formation, centesimal composition, amino acid profile, bioactives and antinutritional factors (phytates and α-galactosides). As for the latter, the effect of immersion in aqueous solution will be evaluated for the reduction of α-galactosides (raffinose, stachyose and verbascose). It is expected to offer alternatives for the use of these fractions, especially to obtain protein concentrates with a higher protein content so that they can offer alternatives for the development of new products with greater added value to the production chain of these bean species.
