Instant controlled pressure drop technology is a thermo-mechanical process that in this process, raw materials are subjected to high pressure saturated steam for a short period of time followed by a sudden pressure drop toward vacuum. As a result, autovaporization of volatile compounds will occur which cause the expansion of sample tissue and porosity increases, which will have some advantages regard to drying and extraction of different compounds from plants. Up to now, DIC has been used on several applications such as drying of strawberries, potato and fish, decontamination of milk powder, texturing of coffee beans and various fruits, extraction of non-volatile molecules like flavonoid and volatiles from some plants such as rosemary, Algerian myrtle leaves and orange peel. The aim of this study is the evaluation of different applications of this technology in food industry.
