dc.description.abstractRed banana is rich in bioactive compounds and nutrients but deteriorate rapidly due to its abundant moisture content. To enhance its stability and health benefits, processing it into a more stable form is essential. Spray drying is an operational technique for producing fruit powders with improved stability and convenience. This study examines the impact of some spray dryer’s operational parameters on the bioactive attributes of spray-dried ripe red banana powder. The effects of inlet air temperature (150-180 °C), feed pump speed (20-50 rpm), and maltodextrin concentration (25-40%) on the stability of total phenolic content (TPC), total flavonoid content (TFC), vitamin C, and β-carotene were analysed. Results showed satisfactory retention of bioactive compounds, with the highest values of 132.20 mg/100 g, 45.99 mg/100 g, 18.87 mg/100 g, and 0.065 mg/100 g for TPC, TFC, vitamin C and β-carotene, respectively. These values were obtained at operational parameters of 180 ⁰C IAT, 35 rpm FPS, 25% MDC for TPC; 150⁰C IAT, 20 rpm FPS, 32.5% MDC for TFC; 165 ⁰C IAT, 20 rpm FPS, 25% MDC for vitamin C and 165 ⁰C IAT, 35 rpm FPS, 32.5% MDC for β-carotene. These findings underscore the importance of selecting suitable spray dryer parameters to preserve bioactive compounds, offering valuable insights for the food industry in developing functional ingredients with enhanced nutritional properties.
