Fresh food and food products with high water activity are easily degradable.
Drying is one of the most fundamental preservation techniques used to improve
the shelf-life of food. However, drying techniques used for the removal of excess
water from food need to be efficient, economic, and able to create dried food with
high-quality. The drying process needs to protect nutrient compounds, aroma,
texture, and appearance of products. However, due to the emission of hot exhaust
gases from the conventional dryer to the environment, and according to the demand
for the application of green energy, the use of non-conventional dryer with higher
efficiency and faster drying is considered in a recent review. This paper reviews
the mechanisms, advantages, and applications of some conventional and nonconventional
drying techniques in the food industry. These include hot air drying,
spray drying, electrohydrodynamic drying, infrared drying, radio frequency
drying and microwave drying.
