DOIAbstract
The evaluation of functional properties of different chia protein hydrolysates (CPH) and their application in O/W emulsions were studied. Enzymatic treatments with pepsin, pancreatin or the sequential action of pepsin–pancreatin were applied to hydrolyse a chia protein concentrate (CPC). Oil-in-water emulsions stabilised with CPC or these CPHs, with or without chia mucilage, were prepared at pH 7 or 10. Particle size, global stability, ζ-potential and rheological measurement of emulsions were determined. CPH presented higher (P ≤ 0.05) solubility and surface hydrophobicity levels, exhibiting better emulsifying properties than CPC. Emulsions with CPH presented smaller (P ≤ 0.05) droplet sizes than those with CPC. Regarding to physicochemical...
