The difference between official swallowing and official swallowing

There is no difference between Guan Yan and Guan Yan, but their names are different. The official swallow is an official swallow, which is the top grade in bird's nest. It is said that in ancient times, when sending bird's nest to dignitaries, clean and complete high-quality Bai Yan would be selected separately. Yan Guan means giving up the bird's nest of the powerful, from which Yan Guan came. Yan Guan is one of many domestic swallows, which refers to the white bird's nest with good quality and complete cup shape.

The main components of Yan Guan are: water-soluble protein, carbohydrates, trace elements such as calcium, phosphorus, iron, sodium and potassium, and the important component "neuraminic acid"-"bird's nest acid" which is necessary for human body. Bird's nest acid can promote the information transmission speed of brain nerve cells. Bird's nest acid in breast milk provides immunity for the early growth of infants and improves the absorption capacity of vitamins and minerals in the intestine.

There are some differences between official swallow and pure bird's nest:

1, the official swallow is the golden bird's nest: the bird's nest digests and absorbs minerals with different components, and the color is orange.

2. Pure bird's nest is Bai Yan bird's nest: it is generally milky white or gray, and the color of bird's nest will gradually change from pearl milky white to gray white after it exists for a long time.

The composition of high-quality protein is different: the difference from Bai Yan is mainly due to the higher quality protein in a certain area of Jin Siyan, so the calcium content of bird's nest is also higher, and the air is oxidized to light yellow, so the quality protein of Huangyan is higher than that of Bai Yan.
