  • Patent number: 11896038
    Abstract: The present disclosure relates to inhibited waxy starches and methods for using them. One aspect of the disclosure is an inhibited waxy starch based on maize, wheat, or tapioca having an amylopectin content in the range of 90-100%; and a sedimentation volume in the range of 10-50 mL/g; in which the amylopectin fraction of the inhibited waxy starch based on maize, wheat, or tapioca has no more than 48.5% medium-length branches having a chain length from 13-24 (measured by a valley-to-valley method as described herein), and the starch is not pregelatinized. Methods of using the starch materials in food products are also described.
    Type: Grant

  • Patent number: 5910372
    Abstract: A coating on a substrate which endows the substrate with a desired surface property, the coating comprising a cross-linked polysiloxane containing X'-- and X-groups attached to different Si atoms wherein the groups X'-- are monovalent organic groups which provide the desired surface property and the groups X-- are monovalent organic groups which are reactive with a group on the substrate surface and have a higher surface tension than the groups X'--, said coating being bonded to said substrate by reaction of X-groups with substrate surface groups reactive therewith. In one embodiment a non-wetting coating is provided wherein the X'-- group has the formula CF.sub.3 Z-- where Z is a divalent organic group or the formula CH.sub.3 (CH.sub.2).sub.t where t is at least 3.
