A review on plum drying

Plum has high consumption rates throughout the world while drying as a common way for increasing its shelf-life is inevitable. But, drying this agricultural product is highly energy-intensive since it has high moisture contents. Hence, any energy saving procedure for drying such an economic product is warmly embraced by plum drying industry. In the present review, based on perusing the plum drying-related papers, it was concluded that the conducted studies on plum drying can be generally categorized in three groups: Plum pre-treatments which highly focus on speeding the rate of drying through application of some mechanical/chemical methods mostly with energy saving perspectives; Mathematical modeling and simulation of plum drying for prognosticating the given process and also the plum drying kinetics. Fortunately, the pre-treatments used were reported to be effective in decreasing the time and the total consumed energy for plum drying.
