Smart Packaging to Ensure Food Safety
Smart packaging is important to monitor the freshness of food items during the packing, transport, storage and display at the marketplace. This would help in increasing the shelf-life of food products by introducing anti-fungal and anti-microbial surfaces, improving heat-resistance properties, detecting biochemical changes and altering the permeation behaviour of foils. Nanosensors can act as monitoring systems to:
• measure the physical parameters like humidity, pH level, and temperature
• reveal the gas mixtures
• detect pathogens
• control freshness and decomposition
