Post-harvest losses of fruits and vegetables in India are estimated to be around 20 - 25%. Food processing and preservation technologies can help reduce the post harvest losses and add value to the agri- horticultural produce. Processing and preservation greatly help extend the availability of these commodities over longer periods and open up market opportunities in domestic and export markets. Drying is one of the oldest methods of food preservation. Drying makes produce lighter, smaller and shelf stable. The energy scenario in India is complex and is beset with many problems. The demand for energy is increasing day by day with the increase in industrialization. It is anticipated that the gap between demand and supply of energy is going to be 10 to 15% every year. Renewable Energy sources like solar energy can be used for drying of food and agricultural commodities with minimal impact on nutrient loss while effectively addressing the environmental concerns. Solar drying enables preservation and value addition to perishable agri-horticultural products into high value added nutritional and health food products at zero energy cost. Solar dried products offer excellent domestic and export market opportunities to the entrepreneurs.
