INTELLIGENT PACKAGING TECHNOLOGY IN FOODS AND CURRENT APPLICATIONS

Intelligent packaging is the newest packaging system in food packaging technology. Increasing demand for innovative packagings by producers, retailers, and consumers to monitor quality and safety of food has led to arise intelligent packaging. The term “intelligent” refers to the response to changes occurring inside or outside packaging and transferring status of the product to consumers. Intelligent packaging, besides the primary functions of packaging, provides preventing or reducing food waste, ensuring food safety, monitoring quality and nutritional value of product. Recent studies have focused on the development of intelligent packaging devices such as color-changing barcodes and labels based on temperature and deterioration, colorimetric indicators providing leakage control of products packaged in a modified atmosphere, color-changing films depending on the degree of maturity of fresh products, and biosensors. In this review, intelligent packaging systems, the working principles of these systems, and recent information about intelligent packaging and food applications are presented
