Customers who are unfamiliar with bird saliva may be shocked to hear that such a rare and sought-after ingredient has an exceptionally bland flavor. Actually, the texture of edible bird’s nests—which resembles soft jelly or gelatin—is what makes their flavor the most intriguing.

Crab, Chinese ham, ginger, and other umami-rich seafood flavors are frequently added to savory versions and cooked into a delectable soup.

Chinese chefs combine herbs and rock sugar to make a delicate and sweet dessert soup. The majority of the time, bird’s nest soups are served as a component of a lavish banquet meal.

Abstract An extraction method for a bird’s nest extract comprises: extracting a broken bird’s nest aqueous solution for 30 minutes to 12 hours at the temperature of 30 to 60°C, and stirring and vacuumizing the solution at the same time; then adjusting the temperature to 30 to 40°C, and adding protease for hydrolysis for 1 to 12 hours; stopping a protease reaction; and performing filtration, concentration, and sterilization, so as to obtain bird’s nest extract liquor. The method effectively retains sialic acid and protein.
