Polymeric materials are described which have a bioflavonoid coating, the bioflavonoid content of the coating comprising at least naringin and neohesperidin. The use of such coated polymeric materials is also described as well as the process for making the coated polymeric materials.

A method for treating a perishable product including determining a desired product treatment outcome selected from sanitation, protection, preservation, or enhancement of the perishable product; directly applying a substance to the surface of the perishable product after harvesting using a carrier; wet or dry washing the perishable product; and packaging the perishable product. A system for treating a perishable product with a substance treatment including one or more devices for directed substance application to a surface of the perishable products prior to final packaging of the perishable product using a carrier; and wherein the one or more devices is an electrostatically charging device or a nebulizer. Embodiments of the invention enhance the efficacy of sanitizers and other functional substances for increasing the quality, safety, and overall shelf life of perishable products through improved coating and distribution of the sanitizers and functional substances on the surface of perishable product.

The invention consists of novel food coatings, compositions, and products, and methods of preserving foods and of protecting against damage and/or spoilage to improve appearance, shelf life, and marketability of the foods.

Food packaging material comprising a polymeric material and a natural antioxidant. The natural antioxidant may be extracted, isolated and/or derived from plant material. A method for forming a food packaging material is also provided, comprising forming a mixture comprising a natural antioxidant and a polymeric resin and processing the mixture to form a food packaging material.

The present disclosure relates to compositions, solutions, and methods for extending the shelf life of food compositions. For example, the disclosure is directed to food compositions or solutions comprising silk fibroin. In some instances, the compositions may be coated with a silk fibroin layer. The disclosure is also directed to methods of preparing food compositions. The methods include spray-coating, dip-coating, or mixing the food compositions with fragments of silk fibroin.

Methods and compositions maintain the freshness of loaf-type food products in a sauce or gel of suitable viscosity for an extended period. When the loaf-type food products are emptied from a container, the sauce or gel covers the exposed surfaces of the loaf-type food products and does not drip off or dry out. After more than six hours, the loaf-type food products still retain their original color and fresh wet appearance without any crust formation. Accordingly, the methods and composition can solve problems associated with the rapid crusting/drying, color change, off odor, staleness and reduced visual appeal of the loaf-type food products after they have been exposed to air for long time periods.

A method of forming a material structure from structural units contained within a liquid solution in a spray head is described. The liquid solution includes a solvent and a solute, the solute comprising a plurality of the structural units, the structural units including monomer units, oligomer units, or combinations thereof. The method comprises forming droplets of the liquid solution including the structural units, and spraying the droplets on a substrate, thereby substantially increasing the reactivity of the structural units within the droplets relative to the structural units within the liquid solution in the spray head. The increase in reactivity can result from the droplets containing an excess of a particular ion, the ion excess resulting from a voltage applied to conductive walls of the device which dispenses the droplets. The material structure is then formed on the substrate from the more highly reactive structural units within the droplets.
