Yanzhan:
After plucking, the intact Yanzhan has less clean impurities and good color. According to the completeness of the cup shape, Bai Yan cups can be divided into different grades, among which Bai Yan is the best grade, with large and perfect cup shape and compact fibers. According to the different nesting sites in Jin Siyan, swallow cups can have many forms, such as big triangle, triangular cup, flat cup and round cup. According to the different processing methods, it can also be divided into dense lamp and sparse lamp.
Although the shapes and processing methods of these swallowtails mentioned above are different, there is no difference in their own nutritional components. Swallowtails are the best kind of bird's nest, and they are first-class in nutritional value, foaming rate, taste and appearance. Swallowtails are the best choice if they have sufficient budget or need gifts.
Swallow strips:
In the process of plucking, packaging or transportation, many complete swallows can't be shaped because they are squashed and crushed, and those thick bird's nests are swallow strips. The taste of Yan tiao is slightly worse than that of Yan Zhan, but the nutritional value is actually similar. Because there is no shape of Yan Zhan, the price is lower than that of Yan Zhan, and the cost performance is very high.
swallow's horn:
swallow's horn is the part used by Jin Siyan to fix the two ends of bird's nest, and it is the "load-bearing beam" of bird's nest. When trimming the swallow's cup, the irregular part of the swallow's cup corner is trimmed down to be angular, so it is called swallow's horn.
Because Yan Jiao is the bearing angle at both ends of Yan Zhan, its texture is much harder and more chewy than other parts, but its hair head is small and it takes longer to soak, and its nutritional value is similar to that of Yan Zhan and Yan tiao.
Minced Swallow:
Minced Swallow is the tiny pieces formed by crushing during picking or transportation, as well as shredded swallows falling down with fluff during processing. After stewing, the taste is poor, and the nutritional value is also the worst among these kinds of bird's nests. It seems that the price is low, but the cost performance is not high, and the probability of bleaching and counterfeiting is high, so it is generally not recommended to buy minced Swallow.
