  • Method of peroxide thinning granular starch
    Patent number: 3975206
    Abstract: An improved method for thinning starch in the granular state employing hydrogen peroxide and metal ion catalysts in an aqueous suspension, free of buffer additions. The thinning action proceeds in acid pH to the desired viscosity level, and is stopped by the addition of sodium metabisulfite, or other reducing agent to remove residual hydrogen peroxide. The aqueous suspension is then neutralized, and the usual purifying and drying steps are effected on the granular product.
