What is the duck blood in hot pot restaurant made of?

First of all, duck blood on the market is very similar to pig blood, but the output of duck blood is much lower than that of pig blood. The most important thing is that the nutritional value of duck blood is much higher than that of pig blood, so the duck blood in many hot pot restaurants is actually replaced by pig blood, and the practice is quite simple. Basically, a lot of water is injected with pig blood. Although the injected pig blood is diluted a lot and feels like duck blood, there is still a big difference when you look closely, that's all. It looks not rosy and shiny!

Some "black-hearted" vendors, driven by interests, will eat a lot of pigments on pig blood, making the color of pig blood similar to that of duck blood, making the color very attractive. If you use food pigments, that's ok, even cheap industrial pigments will do great harm to your body! However, this kind of injected pig blood has a very obvious feature, that is, it is extremely difficult to preserve and easy to rot and deteriorate, so many people add preservatives to it to extend the shelf life or put it in the refrigerator for a long time!

There are even more shocking merchants who finally use a chemical component called an expansion agent in order to increase pig blood production. In this way, the pig blood with expansive agent will become very bright red, almost exactly the same as the real duck blood, which is difficult for non-professionals to distinguish. Moreover, the pig blood added with leavening agent makes the price very low. Basically, a large box of such fake duck blood can be bought for 2 yuan on the market!

So in fact, some very cheap duck blood can't be real duck blood at all, but very cheap pig blood. So, how to distinguish between true and false duck blood? It can be seen from the following four points. Look at the color first, the color of real duck blood is deep red, and the color of fake duck blood is a bit abnormal. Second, real duck blood smells like blood, and fake duck blood has no taste at all!

Three-pinch feel, real duck blood is elastic, it will be flocculent when pinched, and fake duck blood will be broken into slag when pinched, and the hands are not smooth at all, and even the fingers are dyed red. Fourth, taste the taste. After the real duck blood is cut, there will be many small pores. The longer you cook, the more delicate and refreshing it will be. After the fake duck blood is cut, it will show large pores or no pores, which is chewy and very difficult to cook!

Therefore, when eating duck blood, you must observe it carefully. Don't think it's true after eating fake duck blood. In addition, the supermarket also sells boxed duck blood. We can look at the ingredient list. If the first ingredient list is fresh duck blood, then water and salt, we can buy such duck blood. The order of the ingredient list is basically arranged according to the amount of ingredients added. Many foods and drinks are like this, so take a closer look when you have time.
