The invention provides a composition and smart packaging methods for extending the shelf life of the agricultural produces. The composition comprising active ingredients, which act as a signal molecule to activate a defense mechanism with a flower, greens, fruit, or vegetable. The product is designed in the desired form (like sachet, Spray, crate, covering paper, etc.), which includes the encapsulated powder of the active ingredient which is released in a sustained manner near the farm/agricultural produce. When the volatile active ingredient is released it slows down the ethylene biosynthesis pathway and restricts microbial growth of fresh produce without any expensive technologies (refrigeration) and harmful chemicals (toxic). It can be adopted to any stage of the fruits and vegetable supply chain.

A package comprises: a sterile barrier packaging film; self-sterilizing components comprising: a plurality of chlorite ions and water, wherein the self-sterilizing components are substantially free of an energy-activated catalyst and of an acid-releasing compound; a package interior formed by hermetically sealing the sterile barrier packaging film; and a headspace within the package interior comprising carbon dioxide present in an amount of greater than or equal to 5% by volume of the headspace. When the package is exposed to ultraviolet (UV) light having a wavelength of 254 nm, the chlorite ions react with the water to generate chlorine dioxide (ClO.sub.2), which is released into the headspace. In the absence of any UV light, there is not chlorine dioxide (ClO.sub.2) generation.

Packaging containers for preserving the freshness of contents placed therein, such as pastries, doughnuts, baked goods, coffee, fruits, vegetables, and other perishable food items, are disclosed. The packaging containers include a liner that is capable of creating an air-tight environment within the container, which in turn, helps to preserve the freshness of the contents and protects the contents from air, humidity, bacteria, or other materials that may have a deleterious effect on the contents.

Apparatuses and methods are provided for storing and preserving product, such as to extend shelf life of the same. In one optional method, liquid-exuding product is placed in a product containing space of a container atop a platform of a support structure. The container can include an internal compartment having the product containing space. The structure can define the platform for supporting the product. The internal compartment can further include a reservoir, configured to retain liquid, below the platform. At least one of the platform or the support structure can be configured to direct liquid exuded from the product to the reservoir. Optionally, the reservoir comprises or contains an absorbent material for absorbing liquid in the reservoir.

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.

A composition suitable for making edible films or coatings, the composition comprising a conjugate of bio fiber gum and whey protein isolate and at least one food grade antimicrobial.

A freezing packaging film having transparency that produces a color difference (ΔE) of 30 or less on a surface of contents when subjected to frozen storage at −20° C. for 2 weeks, the contents being a reagent containing 0.14 mass % of methylene blue and having L* of 55 to 65, a* of 3 to 9 and b* of 45 to 55 in a L*a*b* color system.

The present invention belongs to the field of active polymer materials. Specifically, it relates to an active polystyrene film that has antimicrobial or antioxidant activity and the method of production of said film. It also refers to wrappers, packages and slice separators (interleavers) that comprise said film.
