Description
Solar ovens use reflected sunlight and insulation to cook food at 70–120 °C, enabling pasteurization and protein/starch denaturation.
Technical
The process relies on radiant heat transfer and convection within an insulated chamber, raising food temperature to the range where proteins unfold, starch granules gelatinize, and Maillard reactions begin. The thermal energy is supplied by concentrated solar radiation, and the rate of heat input is governed by reflector geometry, solar irradiance, and enclosure insulation.
