  • Production of crystalline short chain amylose
    Patent number: 7964718
    Abstract: A process for producing a starch comprises treating a feed starch that comprises amylopectin with glucanotransferase to produce a chain-extended starch, and treating the chain-extended starch with a debranching enzyme to produce a starch product that comprises amylose fragments. At least about 38% by weight of the amylose fragments have a degree of polymerization (DP) of at least about 35.
    Type: Grant
    Filed: January 20, 2010
    Date of Patent: June 21, 2011

  • Enzyme-resistant starch and method for its production
    Patent number: 7955439
    Abstract: A process for producing an enzyme-resistant starch uses an aqueous feed composition that comprises (i) starch that contains at least about 50% by weight amylose, (ii) water, and (iii) alcohol. The concentration of starch in the feed composition is between about 5% and about 50% by weight, and the pH of the feed composition is between about 3.5 and about 6.5. In a first heating step, the feed composition is heated to a temperature between about 130-170° C. for about 0.1-3.0 hours. The feed composition is cooled to a temperature between about 4-70° C. for about 0.1-6.0 hours. In a second heating step, the feed composition is heated to a temperature between about 110-150° C. for about 0.1-10.0 hours. The starch is separated from the majority of the water and alcohol and is dried.
