Abstract: This study developed ready-to-drink high-protein coconut milk fortified with edible bird's nest protein hydrolysate (BP) for elderly nutrition by optimizing coconut protein (CP) and BP levels.High-protein coconut milk (HC) was prepared at CP levels of 25 (HC25), 30, and 35 g/250 mL.The selected formulation was subsequently fortified with BP at 0, 0.15 (HCBP15), 0.30, and 0.45%.Increasing CP levels significantly enhanced the protein, fat, and ash content.However, higher CP levels increased viscosity, reducing the liking scores for viscosity.HC25 achieved the highest liking scores for color, flavor, aroma, aftertaste, and overall liking; therefore, it was selected for BP fortification.BP fortification significantly increased the protein and ash content.Rheological analysis revealed that HCBP exhibited shear-thinning behavior and weak gel-like viscoelastic properties.Higher BP levels reduced liking scores for appearance, viscosity, and overall liking, whereas HCBP15 maintained an overall liking score comparable to the control.Although BP fortification at 0.15% resulted in a slight increase in protein content, BP markedly improved protein quality by enriching essential amino acids, particularly leucine and isoleucine, and significantly enhanced antioxidant activity.HCBP15 represents a promising high-protein beverage with enhanced amino acid profile and antioxidant activity, warranting further evaluation for elderly nutrition applications.
