Food preservation is a topic increasingly being discussed due to market needs, where food from all over the world is required under the best chemical and physical conditions, with minimal waste. Active packaging is defined as the deliberate addition of some components to enhance the properties of the packaging. The various types of active packaging are oxygen scavengers, carbon dioxide emitters and absorbers, ethylene absorbers, ethanol emitters, moisture absorbers, and antimicrobial agents. Smart packaging includes indicators that provide information on product quality and safety over time, such as packaging history, inside and outside atmosphere, oxygen levels, among others. Given the demands on food safety and quality as well as product traceability, there is an exponential increase in the development, production and use of active and intelligent packaging.
