Description Microwave oven is a multi-utility kitchen appliance that can be used for cooking rice. An energy assessment was carried out under normal and controlled methods of cooking, with unsoaked and presoaked rice, in a microwave oven at various power levels. In controlled cooking, the energy consumption substantially reduced, in both unsoaked (14-24%) and presoaked (12-33%) rice, whereas cooking time marginally increased (up to 2min) compared to normal cooking. Presoaking rice resulted in energy savings in normal (5-11%) as well as controlled (3-18%) cooking. Although the absorption of microwave energy in water was 86-89%, the conversion efficiency of electrical to microwave energy was only approx. equal to 50%. Performance of microwave oven was also compared with our earlier studies on electric rice-cooker (ERC) and pressure cooker. Among the cooking appliances assessed, ERC was the most energy-efficient while microwave cooking offered the least cooking time (15-22min). Microwave cooking was on par with pressure cooking, the most commonly followed method of cooking rice, in terms of energy consumption, besides, it offered shorter cooking time.
