    摘要: An improved alcohol-free method for fractionating gluten into gliadin and glutenin fractions is provided where an acidic dispersion of gluten is formed with a reducing agent (e.g., sodium metabisulfite) operable for breaking disulfide bonds in the gluten protein. Thereafter, the pH of the dispersion is raised to cause glutenin to precipitate while leaving gliadin suspended in the dispersion. The respective fractions can then be separated by decanting or centrifugation. In preferred processing, the dispersion is reacidified prior to separation in order to achieve a higher degree of separation of the glutenin and gliadin.
