Technical Abstract: Infrared heating has been considered as an efficient and effective thermal and dehydration processing technology by food and agricultural industries to increase the process and energy efficiencies, improve product quality, and reduce high capital and operation costs. It could be also used for improving food safety and reducing environmental pollution. The technology has great potential to be used for thermal and dehydration processes of various food and agricultural products, such as fruits, vegetables and grains. This paper reviews the latest research results and potential applications of infrared technology for processes of food and agricultural products.
