Abstract: Development of instant germinated black rice (Maejo rice 1A) milk beverage powder fortified with Cordyceps militaris protein isolate was investigated. The base formula was optimized using mixture design, with Formula 8 (24% rice powder, 12% monk fruit sugar, 44% milk powder, 19.7% inulin and 0.3% Palsgaard® RecMilk) selected based on sensory evaluation. The beverage was then fortified with protein isolate at 0%, 3%, 5%, and 7% (w/w). Physicochemical properties, antioxidant activities, and sensory characteristics were evaluated. Protein fortification influenced color, water activity, viscosity, and nutritional composition, while enhancing phenolic-related compounds and antioxidant potential, indicating improved functional properties of the beverage powder. The 7% protein-fortified sample exhibited the highest antioxidant activity across all assays while maintaining acceptable thermal stability. Sensory evaluation showed that 5% protein fortification achieved optimal consumer acceptance (overall score 7.65), outperforming commercial products. The study demonstrates successful development of a functional beverage powder with enhanced nutritional and antioxidant properties through protein fortification.
