  • Patent number: 10851259
    Abstract: The invention provides coated substrates comprising a substrate and a barrier coating on at least one surface of the substrate. The barrier coating comprises (i) vermiculite, (ii) polymer capable of forming a film, (iii) chemical stabilizing agent selected from materials that contain cationic functionality selected from lithium, alkyl C2-C6 ammonium, allyl ammonium, heterocylclic ammonium, morpholonium, ammonium and amino C3-C6 alkyl carboxylic acids; lithium cations in combination with anions selected from carboxylic, phosphoric, phosphonic, sulfonic and fatty acids, lithium chelating agents, and lithium salts, ammonia, C3-C6 amine, heterocyclic amines, lithium hydroxide, morpholine, and morpholine oleate; and (iv) cross-linking agent. The invention also provides articles coated with such coatings, methods and mixtures for making such coated substrates and articles.

  • Publication number: 20170183467
    Abstract: The invention concerns barrier films comprising: (i) a substrate comprising at least first and second coatings on the substrate; (ii) the first coating comprising an inorganic oxide, metal oxide or metallic coating; and (iii) the second coating capable of adhering to the substrates, wherein the second coating is polymeric; wherein the degradation of oxygen transmission rate is reduced when compared to a barrier film without the second coating when the barrier film is subjected to Gelbo-type flexing as described in ASTM F392.

  • Patent number: 6500476
    Abstract: Preservative compositions using GRAS (generally recognized as safe) ingredients are incorporated into a commercially viable three-stage preservation process for mushrooms. The process includes contacting the mushrooms with a high pH solution for microbial reduction; a neutralizing step to return the pH of the mushrooms to their about physiological pH; and an anti-browning step that incorporates suitable antioxidants and ancillary compounds to maintain the color of the finished product. Specifically disclosed is a method for preserving fresh mushrooms comprising the steps of exposing the mushrooms to a aqueous anti-microbial solution with a pH of 10.5-11.5; treating the mushrooms with a pH neutralizing buffer consisting of an organic acid and a salt of an organic acid and then subjecting the mushrooms to a combination of an anti-browning agent, a source of calcium and a chelating agent.
