| Abstract | |
A variety of plant-derived proteins are commercially produced to meet global demand. However, their utilization is still limited. We examined the physicochemical composition and functional properties of three commercial plant protein concentrates: PoPC (potato), RiPC (rice), and PePC (pea) with a focus on the emulsifying properties. PePC showed better water-solubility, emulsifying capacity, and faster interfacial tension reduction than PoPC and RiPC. The low solubility of PoPC and RiPC (<20% at 25 degrees C) was improved by thermal treatment, especially for PoPC (similar to 80%). The oil/water ratio (10:90, 20:80, and 40:60) and pH (3.5, 5.0, and 7.0) influenced emulsion formation and stability for all proteins. PePC-stabilized emulsions were more stable with the smallest droplet size (D32 = 8.5-40.0 mu m) which was correlated with the highest hydrophobicity. Fluorescence microscopy images indicated that RiPC formed a physical barrier around the emulsion droplets. Major differences in functional properties were observed between commercial and laboratory recovered proteins reported in the literature. (AU) | |
