Thermal imaging (TI) is an emerging, non-invasive process
analytical technique suitable for the food industry. While TI
was originally developed for military applications, it has recently
emerged as a powerful non-destructive measurement technique in other industries. This paper provides an overview of
TI theory, equipment, and image processing. Recent advances
and potential applications of TI for food safety and quality
assessment such as temperature validation, bruise and foreign
body detection and grain quality evaluation are reviewed
