  • Reduced molecular weight native gellan gum
    Patent number: 6242035
    Abstract: This invention provides reduced molecular weight gellan gums. The reduced molecular weight gellan gums of this invention generally have a weight average molecular weight less than about 1.7×106, and typically in a range of about 1.2×106 to about 9.3×105. This invention also provides compositions, e.g., solutions and gels, comprising reduced molecular weight gellan gums. The reduced molecular weight gellan gums of this invention may be prepared by any method which reduces the molecular weight of polymers. Such methods include homogenization, sonication, radiation, oxidation and hydrolysis.
