摘要:
and an additive, wherein the variables m, n, q, r, Ra, Rb, R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12 and R13 are defined herein. The protective coatings formed from the compositions can be used to prevent food spoilage due to, for instance, moisture loss, oxidation, or infection by a foreign pathogen.
摘要:
Polydimethylsiloxane and/or siloxane (silicone) -derived chemical compounds are used to coating harvested forages to protect against rain and/or other weather damage and to suppress mold and spoilage in harvested forages. The PDMS compound and derivatives thereof are also found to suppress the damage resulting from oxidation within the feedstuff mass. When applied, PDMS coats the feedstuff and is included in the moisture portion of the feed or forage mass. This helps preserve the feed quality and slows the damaging effects of spoilage organisms and oxidation.
摘要:
A process for preparing a composite which provides sustained release of chlorine dioxide which includes mixing a hydrophilic material containing an amine and a base with a hydrophobic material containing an acid releasing agent, the hydrophilic and hydrophobic materials being adjacent and substantially free of water, to form a mixture. The mixture is exposed to chlorine dioxide which reacts with the amine to form iminium chlorite which is decomposed by the base to form a chlorite salt within the hydrophilic material. The hydrophilic material is capable of releasing chlorine dioxide upon hydrolysis of the acid releasing agent.
摘要:
Fresh produce is preserved by coating the exterior surface of the produce with a coating composition comprising an aqueous solution of from about 1 to about 20 percent by weight of substantially hydrolyzed cold water insoluble polyvinyl alcohol, about 0.1 to about 10 percent by weight of low molecular weight cold water soluble starch, and about 0.03 to about 5 percent by weight of surfactant. Optional constituents include antimicrobials and plasticizers. The coating composition is effective to control respiratory exchange, i.e., the passage of gases, particularly oxygen, ethylene and carbon dioxide, into and out of the produce, thereby to control maturation and ripening of the produce.
摘要:
A composite for retarding microbiological contamination containing a hydrophobic material containing an acid releasing agent, and a hydrophilic material containing anions that are capable of reacting with hydronium ions to generate a gas. The hydrophilic and hydrophobic materials are adjacent and substantially free of water, and the hydrophilic material is capable of generating and releasing the gas after hydrolysis of the acid releasing agent.
摘要:
A method of retarding bacterial, fungal, and viral contamination and growth of molds on the surface of a material and/or deodorizing the material by treating a surface with a composite which does not release chlorine dioxide in the absence of moisture, and exposing the treated surface to moisture to release chloride dioxide from the composite into the atmosphere surrounding the material.
摘要:
An edible product having a thin inorganic coating on at least a portion of its surface. The coating preferably forms a moisture/oxygen barrier to result in a coated edible product having an improved shelf-life. The edible products include food and pharmaceuticals. The inorganic materials used for the coating include SiO2, SiO, MgO, CaO, TiO2, ZnO and MnO. Processes and apparatuses for depositing a thin film of inorganic material onto an edible substrate are also disclosed. The preferred processes include sputtering and vapor deposition. The preferred apparatus provides for the continuous production of coated edible products.
