The primary purpose of food packaging is to protect the food against attack from
oxygen, water vapor, ultraviolet light, and both chemical and microbiological contamination.
Active packaging
as originally described by Labuza and Breene (1989) is used successfully to increase the shelf life of processed
foods and meet consumer demands in terms of providing high-quality products that are also fresh and safe.
Active Packaging is an innovative concept that can be defined as a mode of packaging in which the package, the
product, and the environment interact to prolong shelf life or enhance safety or sensory properties, while
maintaining the quality of the product.
