Abstract: Food waste is a worldwide problem to be solved urgently. Intelligent packaging allows real-time tracking of products, and provides supporting information for food packaging decision making, thereby reducing food loss. This article reviews the concept of intelligent packaging, the intelligent packaging technologies (time-temperature indicators, leak indicators, freshness monitoring technology, maturity monitoring technology, barcode technology, radio frequency identification technology and augmented reality technology), and the problems of applying them in the food field. It proposes that intelligent packaging would develop a low-cost, multi-functional and safe direction. This review is expected to help promote the intelligent packaging technologies to reduce food waste.
