Dehydration of organic material is undoubtedly a controlled attempt to conserve or construct a novel construct that will satisfy functional devotions. Food dehydration is reviewed in light of the latest progress in food materials research. Understanding the mechanics behind the drying process is crucial in food and agricultural product dehydration. Among the most crucial steps in preserving food is dehydration. Food drying innovations include photovoltaic, thermal imaging, microwave-assisted, and comparable hybrid technologies. According to a recent study, unique food dehydration technologies might increase drying efficiency by decreasing energy usage while improving product quality. Unique drying methods reduce food component degradation and create novel items for customers. Each method’s use of specific foods will be reviewed in this chapter.
