Freeze-dried bird’s nests are pre-frozen in the bird’s nest at minus 40°C using a food freeze dryer, and then the solid water is sublimated under a vacuum environment to achieve an absolute moisture content of less than 5%, leaving the original structure of the bird’s nest intact. It effectively avoids the thermal loss of sialic
