Progress of Freshness Indicator Used in Fresh Food Packaging

Freshness is an important evaluation index of fresh food in the process of storage, transportation and sales. Conventional food packaging fails to meet the requirements of consumers for food freshness monitoring. The emergence of intelligent packaging technology makes it possible to detect freshness. Intelligent packaging technology uses indicators and sensors to monitor the physical, chemical and biological changes of food at storage to reflect the state of packaged food or the environment during transportation and storage. This paper introduces the principle, key technology and research progress of intelligent packaging technology in the freshness detection during the storage and transportation of fresh food from the indicators and sensors. The problems of intelligent packaging technology are finally summarized and the future development is prospected.
