Provided herein are antimicrobial coating compositions and food packaging materials coated therewith. The coating compositions include at least one antimicrobial active agent and a hydrophilic polymer, such that the active agent is immobilized within the composition.

The present invention discloses a novel nano-composite antibacterial material and a preparation method and an application thereof, and belongs to the technical field of preservative materials. The novel nano-composite antibacterial material disclosed by the present invention is prepared by mixing a dimethylimidazole solution, deionized water and a zinc nitrate solution to prepare a metal-organic framework carrier, compositing with nisin to form a nano antibacterial composite material, separating out from a solution in a precipitate form, centrifuging, removing a supernatant, cleaning and re-suspending with the deionized water. The novel nano-composite antibacterial material prepared by the present invention has an antibacterial effect superior to nisin having a same concentration. The present invention prominently improves an antibacterial activity and thermostability of the nisin under neutral and slightly alkaline conditions, effectively promotes antibacterial property and a usable range of the nisin, and further expands an application field of the metal-organic framework carrier.

Methods of controlling the maturation of plants and/or plant products (e.g. fruit, vegetable, ornamentals, etc.) by manipulating Alternative Oxidase (AOX) activity. An increase in activity hastens the maturation process while a decrease in activity slows or stops maturation.

Disclosed herein is a method for preserving a plant material. The method comprises applying a composition comprising a microwave attractant to the plant material; and then drying the plant material while exposing the plant material to microwave energy, wherein the microwave energy heats the plant material to a temperature effective to inactivate the majority of any browning enzymes in the plant material, and wherein the microwave attractant results in the heating of the plant material occurring at a rate whereby browning of the plant material by the browning enzymes during heating is substantially prevented. Also disclosed are uses of the preserved plant material.

The present invention is in the field of aqueous emulsions that dry into water-insoluble or water-resistant structures that are useful for active packaging, manufactured devices and components, and other applications. The aqueous emulsions of the present invention comprise biopolymers, metal in the form of a salt, nanoparticles or metal oxide nanoparticles, essential oil, and additives such as surfactants and plasticizers. When the components of the emulsion are mixed following the distinctive method of preparation, a water-soluble fluid is obtained, which, upon drying, becomes a water-insoluble or water-resistant solid exhibiting antimicrobial, antioxidative, and other useful properties including tensile strength, elasticity, transparency. The obtained fluid may be applied by spraying, pouring, injecting, 3-D printing, or otherwise formed into a solid product of any geometrical shape including film, foil, or other 3-D shape.
