  • Patent number: 11497236
    Abstract: Starch-based edible coating compositions for preserving food products are disclosed. The starch-based coatings comprise both a polymerized starch, comprising intertwined amylopectin chains and/or amylose chains, and native (unmodified) and/or modified starch granules dispersed in a liquid carrier. When the starch granules are heated to a temperature to induce swelling, the swollen starch granules become embedded in the intertwined amylopectin and/or amylose chains, improving physical properties of the coating needed to extend shelf-life of food products. Also disclosed are coatings made from the coating compositions, methods of making the coatings, and methods of applying the coatings to food products.

  • Patent number: 9605383
    Abstract: Systems and methods for attaching particulate additives to a population of cellulose fibers dispersed in an aqueous solution are described. The cellulose fibers are treated with an activator that forms complexes with them. The particulate additive is attached to a tether that is capable of interacting with the activator, thereby forming a tether-bearing particulate additive. The tether-bearing particulate additive can be added to the activated suspension of cellulose fibers. The resulting interaction between the tether and the activator forms durable complexes that attach the particulate additive to the cellulose fibers. Using these systems and methods, useful additives like starches can be attached to cellulose fibers, imparting advantageous properties such as increased strength to paper products formed thereby. These systems and methods are particularly useful for papermaking involving virgin pulp fibers, recycled fibers, or any combination thereof.

  • Publication number: 20030188738
    Abstract: A novel filler treatment comprising the preparation of swollen starch-latex compositions, prepared in the presence or absence of co-additives, and the addition of the said composition to a filler suspension, has been developed. Use of the treated filler during papermaking improves filler retention and produces filled papers where addition of the filler has only a minimal negative effect on strength properties. The swollen starch-latex compositions can be prepared in a batch or jet cooker, or by mixing with hot water under controlled conditions (i.e., temperature, pH, mixing, mixing time) in order to make the starch granules swell sufficiently to improve their properties as a filler additive but avoiding excess swelling leading to their rupture. The swollen starch-latex composition is then rapidly mixed with the filler slurry, preferably in a static mixer, and added to the papermaking furnish at a point prior to the headbox of the paper machine.

  • Patent number: 5904941
    Abstract: The present invention is directed to a viscosifier prepared by enzymatically hydrolyzing a ungelatinized, granular starch or flour. Such starch or flour is useful as an ingredient in food products, particularly fruit- or vegetable-based products, as a viscosifier and may be used to replace pectin or tomato solids.

  • Patent number: 5827372
    Abstract: A starch cationization process comprises suspending the starch in an aqueous alcoholic alkaline solvent containing a critical level of water (starch to water ratio 1:3 to 3:1), heating the reaction mixture for a few minutes at 30.degree.90.degree. C., adding a cationizing reagent such as 3-chloro-2-hydroxypropyl-trimethylammonium chloride, heating for 1-24 hours at 30.degree.-80.degree. C., neutralizing, centrifuging, washing and drying of the cake to yield cationic starches with degrees of substitution of 0.01 to 0.12. Amphoteric starches are produced by simultaneous or sequential reaction of an anionic reagent with or after the cationic reagent in the aqueous alcoholic alkaline solvent. Solvent recovery and concentration of effluent solids is facilitated by distillation.

  • Patent number: RE44519
    Abstract: Starch compositions, including cationic crosslinked starches, and methods of using those starches in papermaking are disclosed. In particular, a cationized crosslinked starch and use of the starch in the wet end system of a paper machine is disclosed. The starch compositions of the disclosure are particularly adapted for customization for specific wet end systems, and allow for modification to correspond to variations in the wet end of the papermaking machine.
