  • Sprout-damaged wheat flour containing barley alpha-amylase inhibitor
    Patent number: 5047257
    Abstract: A novel procedure for the preparation of a protein which is an inhibitor of alpha-amylase II is described. The protein may be prepared by extracting barley meal with a Tris-HCl buffer and purifying the crude inhibitor thus obtained by a chromatographic procedure. Alternatively, the protein may be prepared by recombinant DNA techniques. The protein can be applied as an additive to sprout-damaged wheat flour which can then be used to provide improved quality bread.
    Type: Grant
    Filed: January 8, 1990
    Date of Patent: September 10, 1991
