Abstract: 
Bird's nest is widely used in Asia and good for consumers' health. The paper focused on optimizing for beverage formulation that contain Salanganes'Nest harvesting at Yen Island, Nha Trang, Khanh Hoa province, Vietnam. The input factors such as Bird's Nests essence, Ginkgo biloba, Chamomile, and Glucosamine were studied. Target functions were pH, viscosity, and DPPH free radical scavenging activity. The results showed that the optimizated beverage formulation value is at the condition as following: Bird's nest essence of 24.79%, Ginkgo biloba of 0.18%, Chamomile of 0,23%, Glucosamine of 0.8%, pH of 5.5, a viscosity of 32.9 cP, and DPPH free radical scavenging capacity of 75.4%. Salanganes'Nest beverage possesses antioxidant activity and good status that is useful for healthy of human.
