Method for producing modified pea protein

USPTO issued patent US12588686B2 to Ajinomoto Co., Inc. on March 31, 2026, granting intellectual property protection for methods of producing modified pea protein. The patented process includes adding acid to a water dispersion of pea ground product to collect precipitate, followed by an enzyme reaction using protein deamidase—steps that may be performed in either order. The patent covers various CPC classifications related to food protein processing.
