  • Publication number: 20240051988
    Abstract: A method for enhancing a solubility of a plant protein includes: mixing a plant protein and water, and adjusting the pH value of a resulting mixture of the plant protein and water to 10-12 for dissolution of the plant protein, thereby obtaining a swollen plant protein; treating the swollen plant protein through ion exchange until the pH value of the mixture is 7-8, and filtering the mixture, to yield a first supernatant; separating the first supernatant to yield a second supernatant; and drying the second supernatant, to yield a modified plant protein whose solubility is higher than that of the raw plant protein.
