US (GA): Thermal imaging could help keep produce fresher for longer

Nov 07, 2024

Before fresh produce arrives at the grocery store, it must be carefully harvested and maintained across long periods. A recent University of Georgia review suggests new temperature measuring technologies could make that process much simpler, amid growing agricultural challenges fueled by fluctuating climates.

Maintaining temperature, humidity, and light is critical to ensuring fruits and vegetables don't spoil or deteriorate rapidly. Temperature spikes are the root of adverse outcomes like premature spoilage and rotting, so monitoring these changes quickly and accurately is key.

Researchers say thermal imaging technology could help control temperatures before and after harvesting fruit and vegetables.

"Measuring temperature in food processing environments has to be done right," said Kevin Mis Solval, lead author of the study and an associate professor in UGA's College of Agricultural and Environmental Sciences. "We do it on a regular basis to make sure we have the proper conditions for producing safe products, but it may not always be done practically. These types of thermal imaging tools are not only feasible but cost-effective and good at measuring temperature profiles. That is beneficial for a farmer or food processing facility."
