In the present study, effect of an active reduced oxygen packaging atmosphere on the shelf life of barracuda (Sphyraena jello) fish steaks stored at 0-2oC was analysed. Barracuda steaks of 2.5 cm were divided into two batches; the first batch served as control, which was aerobically packed (AP) inside a multilayer film pouch of ethylene-vinyl alcohol (EVOH) with high barrier properties and the second batch packed in EVOH pouch was attached with a commercial oxygen (O2) scavenger (OS). OS reduced the amount of O2 inside the package to less than 0.01% within 24 h. On 12th day of storage, there was a 2 log difference in the total mesophilic count of steaks in OS attached pouches, compared to control. The 2 mg malonaldehyde kg-1 limit of thiobarbituric acid (TBA) value, which is an index of secondary lipid oxidation, was exceeded in control, on 12th day of chilled storage. Based on the sensory score, control was rejected on 12th day, while OS steaks were acceptable till 20th day. The results indicate that OS is efficient in enhancing the storage life of fish by limiting the oxygen present inside the package.

Many plastic packaging materials manufactured today are composites made of distinct polymer layers (i.e., multilayer films). Billions of pounds of these multilayer films are produced annually, but manufacturing inefficiencies result in large, corresponding postindustrial waste streams. Although relatively clean (as opposed to municipal wastes) and of near-constant composition, no commercially practiced technologies exist to fully deconstruct postindustrial multilayer film wastes into pure, recyclable polymers. Here, we demonstrate a unique strategy we call solvent-targeted recovery and precipitation (STRAP) to deconstruct multilayer films into their constituent resins using a series of solvent washes that are guided by thermodynamic calculations of polymer solubility. We show that the STRAP process is able to separate three representative polymers (polyethylene, ethylene vinyl alcohol, and polyethylene terephthalate) from a commercially available multilayer film with nearly 100% material efficiency, affording recyclable resins that are cost-competitive with the corresponding virgin materials.
