Smart packaging systems have widely been used in raw and processed food products for quality analysis and Squality management ensuring food safety. Active packaging and intelligent packaging technologies are two different forms of smart packaging. Active packaging applies gas emitters, gas and moisture absorbers, scavengers, chelating agents and so on in/on the packaging for maintaining and extending the shelf life of the food products. Whereas, intelligent packaging systems uses different indicators as tool for detecting and communicating the food quality to the consumers. Extensive research has been conducted to find out a sustainable and safe solution for the packaging industries, where a single component can serve the dual purpose. Anthocyanins are one of the active compounds which have been extensively explored for their application in active and intelligent packaging systems. Anthocyanins are plant constituents which impart the bright and attractive orange, red, purple, and blue colors to most fruits and vegetables, and flowers. The antioxidant and antimicrobial properties help in improving the product shelf life, and the pH sensitive pigment is used as quality indictor in packages. This review article focuses on recent studies that deal with the use of anthocyanin for smart food packaging applications, giving a thorough understanding of the benefits of anthocyanin-based natural dyes for shelf-life indicator when applied to package material specific to foods. The potential of anthocyanin opens the path to technological developments for commercialization of the technology for different food commodities.
