Saga seeds (Adenanthera pavonina, L) contain protein and lignoseric acid and may serve as potential functional food and beverages This study aims to utilize saga seed in producing saga milk with its physical property such as stability and fat globule as well as chemical properties. Soy milk was added to reduce strong beany flavour in saga milk. The saga milk fat globules were reduced by ultraturax or mini homogenizer at 8,000 rpm at different homogenization time. A two factorial completely randomized design was carried out with two replications. Saga milk and soy milk ratio (A): a1 (100 % saga milk); a2 (80 : 20), a3 (75 : 25), and a4 (70 : 30), respectively; and homogenization time (B) : 0, 10, 20, and 30 minutes (b1, b2, b3, and b4, respectively). Fat globule, protein, and fat contents, fatty acids profile, soluble solids, and pH values were analyzed. Milk flavour compounds were analyzed using GCMS. Sensory evaluation was carried out by preference test. The more soymilk added resulted in significant increase of protein, total soluble solid (p=0.05), significantly reduce size of fat globules and pH value (p=0.05) and also reduced unpleasant flavour. The saga milk was accepted based on sensory evaluation; saga milk stability was good. Saga milk has dominant content of essential fatty acid including oleic acid, linoleic acid and lignoseric acids. The unpleasant flavor was dominated by hexanal compounds but the typical compounds in saga milk are Dihydroedulan II; Pyrazine, 2-Methoxy-3-Isobutyl, and Benzaldehide-4-Methyl. Formula saga milk: soy milk = 70: 30 is saga milk that is worth producing.
