Abstract: A dried distiller soluble based bioadhesive composition and method for producing the dried distiller soluble based bioadhesives are disclosed, as well as derivatives thereof. The produced dried distillers solubles derives from co-products of corn fermentation facilities, and is advantageously comprised in part of water-soluble proteins. The method for producing the dried distillers solubles generally involves separation and/or introduction of targeted constituents and/or physiochemical treatment to facilitate use as an adhesive. Use of the method and bioadhesive compositions disclosed herein will improve the economics of fermentation by increasing co-product value, reducing plant-wide energy utilization, decreasing waste and emissions, and increasing overall product yield from each bushel of corn consumed.
Abstract: The present disclosure provides methods for manufacturing plastic materials from decolorized blood protein. The method includes the following steps: contacting the blood protein an oxidizing agent to form a blood protein composition that includes unreacted oxidizing agent; removing at least a portion of the unreacted oxidizing agent from the blood protein composition to form a decolorized blood protein composition; and treating the decolorized blood protein composition in the presence of a plasticizer with sufficient pressure and temperature to form the plastic material. The present disclosure also provides a plastic material including a blood protein residue having a percent whiteness of 35%-100% and a plasticizer.
Abstract: The present invention relates to a process for producing protein microparticles in dilute organic acid solutions and in the absence of an alcohol such as ethanol. The microparticles are formed by dissolving a cereal prolamin protein in a concentrated organic acid solution with agitation and then diluting the solution with an aqueous solution. Protein microparticles having vacuoles are thus formed. The protein microparticles may be used to form powders, films, coatings, matrices, scaffolds and the like. Complete films can be formed from the protein microparticles of the invention.

Abstract: The top of an opening of a glass container is hot end coated, and then is coated with a coating agent of an aqueous solution containing casein and polyphenol and one or more members selected from copper sulfates, calcium hydroxides, and ferric chlorides. Thereafter, a sealing material, to which a thermoplastic resin is applied, is adhered to the top of the opening of the glass container, whereby the water resistance of the sealing of the glass container becomes excellent irrespective of weathering of glass.
Abstract: The invention concerns lake compositions based on natural macromolecules (gelatin, chitosan, pectine etc.) with possible additions of vinyl polymers, metal-alcoxides etc., characterized by a barrier effect modulated in situ, in particular as a function of the relative humidity in the exterior ambient.

Abstract: The, present invention provides useful adhesive compositions having similar adhesive properties to conventional UF and PPF resins. The compositions generally include a protein portion and modifying ingredient portion selected from the group consisting of carboxyl-containing compounds, aldehyde-containing compounds, epoxy group-containing compounds, and mixtures thereof. The composition is preferably prepared at a pH level at or near the isoelectric point of the protein. In other preferred forms, the adhesive composition includes a protein portion and a carboxyl-containing group portion.

Abstract: Liquid, injectable, aqueous solutions are transformed in situ to an expandable foam-like, space filling, and adherent biomaterial. Preferably, the foam-like biomaterial is the reaction product of a two-part liquid system to achieve the in situ formation thereof. The liquid system is generally comprised of a protein solution and a cross linker solution which may either be premixed and then applied to a site in need of the biomaterial, or simultaneously mixed and delivered through an in-line mixing/dispensing tip directly to the site. In especially preferred embodiments, an expandable foam-like biomaterial includes the reaction product of human or animal-derived protein material and a di- or polyaldehyde in the presence of a bicarbonate and an acidic titrant amounts sufficient to impart a cellular foam structure to the material.
