  • Highly flexible starch-based films
    Patent number: 6649188
    Abstract: Film-forming compositions are disclosed that can comprise, on a dry solids basis, 25 to 75 percent by weight of certain starch derivatives and 25 to 75% primary external plasticizer. The starch derivatives can be chemically modified starches that range in molecular weight from 100,000 to 2,000,000. The high levels of plasticizer in the films give excellent film flexibility and integrity. The films are also resistant to penetration by water, oil and/or grease.
    Type: Grant

  • Modified starch as a replacement for gelatin in soft gel films and capsules
    Patent number: 6375981
    Abstract: Film-forming compositions are disclosed that can comprise, on a dry solids basis, 25 to 75 percent by weight of certain starch derivatives having a DE less than about 1, 25 to 75% plasticizer, and 0.1 to 15% hydrocolloid gum. The starch derviatives can be chemically modified starches which range in molecular weight from 100,000 to 2,000,000. These starch-based systems can completely replace gelatin in edible film-forming applications such as soft and hard gel capsules.
