Abstract

This study investigates the effects of electrodialysis (ED) of a 3.5% (w/v) pea protein solution on the changes in physicochemical properties, mineral profile, phytic acid, and polyphenol content. During 120 min of ED process, the electrical conductivity decreased by 62.2%, and the pH dropped from 7.04 to 5.37. Significant demineralisation was observed, with potassium, calcium, and sodium being the most reduced by 88.7%, 79.1%, and 61.4%, respectively. The produced demineralized powders showed a reduction of ash content up to 52%, with a consequent increase in protein content from 69.5 ± 0.35% to 83.5 ± 0.42 % (w/w). Phytic acid content decreased by 43.2%, from 1790 ± 112 to 1017 ± 41.1 (mg/100 g), following a second-order kinetic; similar kinetics were observed for polyphenol content that was reduced by 60.5%, leading to lighter and less reddish pea protein-based ingredients. These findings demonstrate that ED is an effective method for improving pea protein ingredients by reducing antinutritional factors and enhancing visual quality.

期刊介绍： The journal publishes original research and review papers on any subject at the interface between food and engineering, particularly those of relevance to industry, including: Engineering properties of foods, food physics and physical chemistry; processing, measurement, control, packaging, storage and distribution; engineering aspects of the design and production of novel foods and of food service and catering; design and operation of food processes, plant and equipment; economics of food engineering, including the economics of alternative processes. Accounts of food engineering achievements are of particular value.
