Abstract:
Pearl millet, an abundant source of essential macro-and micronutrients, carbohydrates, protein, dietaryfiber, lipids, and phytochemicals. However, the conventional techniques significantly influence the nutrient content and functional properties that are of importance in food application. Improved techniques are necessarily applied for value addition to give out more products of wide acceptance, thereby promoting food security. Therefore, the main objective of this work was to investigate the effect of hot air assisted radio frequency (HARF) treatment at different exposure periods (5, 8, 11 &14 min) on physical (moisture, colour, water activity, bulk density, tapped density, CI and HR) and functional (WAC, OAC, WSI) properties of pearl millet. As the exposure time increased, the moisture content and water activity were reduced significantly while the colour values and bulk density changed insignificantly. The functional properties such as WAC and WSI decreased insignificantly while the OAC was insignificantly increased as the exposure time increased.
