What is bird's nest made of

Bird's nest is a precious tonic. To put it simply, it is the saliva secreted by the swiftlet of the order Apodales, combined with some other substances to make the bird's nest. It is divided into house bird's nest and cave bird's nest. Its main component is protein. It also contains a variety of amino acids and minerals. It can play a very good role in health care for the body. It has good effects in beautifying the skin, improving immunity and preventing diseases.

Ingredients

The main nutrient in bird's nest is protein, which contains 1 essential amino acid (lysine) and 3 conditionally essential amino acids. Bird's nest is often eaten with sea ginseng to enhance its efficacy. There are 8 essential amino acids and 13 conditionally essential amino acids required by the human body.

Main Origin

The main production areas of the fish are in caves on deserted islands near the coast of Myanmar, from the Philippines in the east to the west. They are mostly found in the waters of Southeast Asia such as Indonesia, Malaysia, Sandakan, Singapore and Thailand, as well as the South China Sea islands of my country.

Among them, Indonesia has the best quality bird's nest and the largest production because its weather and environment are most suitable for swallows to live together, followed by Malaysia. According to statistics, by the end of 2010, Indonesian bird's nests accounted for 85%-90% of the global bird's nest production, Malaysia accounted for 5%-10%, Thailand accounted for 3%, and Vietnam, the Philippines and other places accounted for about 2% (refer to the data of the Hong Kong Trade Department for several years). A subspecies of the Javan swiftlet was once collected on Yannan Dazhou Island, which can produce edible bird's nests. The short-billed swiftlet is found in southwestern China and southeastern Tibet. The earliest works with detailed records of it include "Bencao Beiyao" and "Benjing Fengyuan". Apodidae

The saliva secreted by various birds of the genus Collocalia (Apodidae) is mixed with their down and condensed on cliffs or farmhouses to form nests. There are six species of swiftlets that can produce bird's nests.

Shopping Tips

First, the place of origin must be fixed: the place where the swiftlet grows affects the quality of the bird's nest production. The more industrially developed the production area is, the more dust and other impurities there are, and the more serious the air pollution is, the darker the bird's nest produced will be. The higher the rainfall and forest coverage area of ​​the production area, the better the bird's nest produced will be and the higher the quality. Many well-known domestic bird’s nest brands come from the above-mentioned production areas.

The second is to look at the head of the bird's nest: bird's nests picked at different times also have different "heads".

Third, check whether the bird’s nest is clean: the less fine hairs the better.

The fourth is the nest-shaped shape: the thinner the ends of the bird's nest are, the more beautiful it is.

Fifth, check whether the bird's nest is dry and light: the one that is dry and contains less water is the best quality. High-quality bird's nest should feel dry to the touch. Wetter bird's nests contain more water and will become moldy if not stored properly.

Six stews: of course, it refers to stewing bird's nests. Good bird's nests are resistant to stewing, and bird's nests that are purely hand-picked are not easy to become watery. After stewing, there will be a rich and refreshing aroma of protein coming to your nose, which is an important indicator of the authenticity of the bird's nest. Fake bird's nest will not have this fragrant protein smell. Chemically processed bird's nest will easily turn into water if stewed for too long.
