Food sensors: Off‐package and on‐package approaches

Abstract

Abstract Food sensors are an emerging technology used in food quality monitoring and safety, potentially decreasing food loss and waste and protecting the health of consumers. Food sensors integrated into intelligent packaging systems are promising to enhance food shelf‐life during transportation, distribution, storage, and selling. In this review, the role of food sensors in the intelligent packaging system, their developments, and challenges are discussed. First, we discuss the motivation behind food sensors in the food quality and safety management system, followed by the background of the intelligent packaging development and factors involved in the food properties monitoring. Then, food sensor approaches, both on‐package and off‐package sensors, were discussed. Following, the examples
