How can bird's nest be divided into true and false?

The first is to look at the identity of bird's nest. The "ID card" of the Bird's Nest refers to the two-dimensional code label that is uniquely coded in the world and can be recognized by mobile phones. Including bird's nest picking environment and time, cleaning technology and time, brand and distributor profile, especially whether China's entry animal and plant quarantine is qualified or not. Consumers can easily get the information of "bird's nest life" by taking an "ID card" on their mobile phones, thus realizing the whole process tracing from the dining table to the bird's nest, effectively ensuring the safety of their imported bird's nest food. Generally speaking, the grade of bird's nest is distinguished according to the integrity of cup, the compactness of fiber, the amount of impurities, color, dryness ratio, physical and chemical indicators, expansion rate and other parameters. High-grade white bird's nest has complete cup shape, dense fiber, less impurities, natural milky white color, good dry ratio and high expansion rate. According to industry experts, bird's nest on the market can be roughly divided into two kinds of packaging: ready-to-eat bottled bird's nest and bulk dried bird's nest. A bottle of 240 grams of instant bird's nest costs about 1000 yuan and can be eaten for 7 ~ 10 days. And a Bai Yan weighing about 6 ~ 9g can be sold to 50 ~ 70 yuan for two or three times. Bottled bird's nest is the easiest to fake. Most of the fake raw materials are tremella and pigskin, because they are also rich in collagen, and the color is equivalent to that of bird's nest. After boiling, they are thick and similar in shape to real bird's nest. People who are not sensible are easily deceived. In Hongkong and Taiwan Province markets, there are also people who promote tremella with the slogan of "cheap and effective collagen plant bird's nest". In addition, some bottled bird's nest, the marked bird's nest content is different from the actual content, so it is also one of the means of counterfeiting. The bulk dried bird's nest with low quality is mostly rigged in weight, and the higher price is sold by increasing the humidity of dried bird's nest. The difficulty of collecting bird's nest makes it precious, and it is precisely because of its rarity that the phenomenon of adulteration of fish beads in bird's nest market has appeared. Various bird's nest brands in the market are not only uneven in quality, but also expensive. "If you really want to buy fakes for such expensive things, you will lose a lot." Therefore, it is best to go to regular specialty stores, pharmacies and large supermarkets to buy bottled bird's nest. Moreover, it should be distinguished from the appearance and taste: authentic instant bottled bird's nest looks like a ray of translucent; It tastes like egg white. I recommend a brand of raw wonton for you, from Shenzhen Sankoushan Trading Co., Ltd., which only takes 20 minutes to eat. It is the best choice for lazy people who love beauty. Raw swallowing is refrigerated because there are no additives.
