the explosion puffing drying for fruits and vegetables at vari- able temperature and pressure difference is a new technology developed in recent years. In this paper, characteristics of explosion puffing drying technology at variable temperature and pressure difference and its products were reviewed. And various factors affecting fruit and veg- etable puffing at variable temperature, such as material characteristics, material pretreatment, puffing parameters, and so on, were described. The principle of material pretreatment for controlling dehydration rate and the problems existing in the current research of this technology were also discussed. Finally, the research direction and development trends of this technology were discussed.
