Bird's nest, also known as bird's nest, swallow root and swallow dish, refers to a nest made by mixing saliva secreted by some Swifts of Swift Family of Swift Order and Jin Siyan of several species of Swiftlet in Jin Siyan with other substances. Bird's nest can be divided into "domestic swallow" and "cave swallow" according to the nesting location. Dongyan has different colors due to the influence of minerals, including Bai Yan, Huangyan and Hongyan, while domestic swallow has only one ivory color.
Bird's Nest is one of the traditional precious foods that China has been eating since the Ming Dynasty. The so-called "blood swallow" on the market is said to be made of "bird droppings" by artificially bred domestic swallows.
Dry bird's nest needs to be stewed in water to make delicious and nutritious instant bird's nest. In addition to protein, bird's nest also has a key nutrient called bird's nest acid, also called sialic acid. If only the content of sialic acid is compared, 1 g of dried bird's nest is equivalent to 40 eggs. Moreover, sialic acid is the most important component of bird's nest, which plays a very important role in nerve development and immunity improvement, especially in the important period of cranial nerve development.
