How to identify the authenticity of stewed bird's nest?

When many customers buy bottled bird's nest, they often take the solid content in the bottle as the selection standard, thinking that the thicker the product looks, the more bird's nest content there is, and the more benefits it will get. But the solid is not necessarily bird's nest. The so-called thickening is only the function of thickener in ingredients.

Food thickener, also known as food gum, is a common food additive and a common fake method for dried swallow cups. It can be dissolved in water and fully hydrated under certain conditions to form a sticky macromolecular solution. Common thickeners include gelatin, pectin, agar, sodium caseinate, Arabic gum, tamarind polysaccharide gum, sesbania gum, sodium alginate (sodium alginate, alginate), xanthan gum, etc. The main function is to improve the viscosity of the system and keep the system in a uniform and stable suspended or turbid state. This is why consumers often wonder why some bottled ready-to-eat bird's nest bought in supermarkets always feel stronger than the dried swallow lamp stewed at home. After the same amount of dried bird's nest is stewed by consumers themselves, the bird's nest sinks to the bottom of the bowl, while hotels and food clubs let it float on the water. In fact, it is not because consumers don't put enough bird's nest, nor because consumers don't have enough time to stew, but it is different from the "ingredients" added by merchants.

Therefore, it seems that the thick instant bottled bird's nest is not because of the high content of bird's nest, but only because of the difference in composition. The solid content marked on the label cannot represent the real bird's nest content, so consumers should be cautious when buying.

Now there is adulteration in the bird's nest market. Recently, the reporter visited Beijing Bird's Nest Market and found that all kinds of bird's nests on 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." This is why more consumers stop at the bird's nest counter and only take a look or turn around for a long time before asking.

Instant 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, marked with solid content rather than bird's nest content, is also one of the means of fraud. 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.
