Abstract
Application of sustainable materials in the production of Smart Packaging (SPM) has recently garnered attention around the world. This is because of its ability to control the packaging system and then act on fresh foods to preserve quality and enhance their shelf-life. In this paper, two methods of SPM production using mechanical and biochemical approaches were reviewed. The mechanical approach is essentially the application of extrusion and injection molding techniques to form granules that are later transformed into sheets by casting into prepared molds. The biochemical approach involves the production of nanocomposites from a mixture of sustainable plant or animal products, like bamboo or keratin from chicken feathers, a starch and plasticizer to form the package. A novel SPM, that can provide protection from in-situ interference, was proposed for food preservation by incorporating Aerotolerant anaerobes, like Cutibacterium acnes, into the matrix of the package during production. This technique can enhance the performance of the SPMs to control the gas atmosphere within the packaging system.
