Distinguish between true and false duck blood:
1, real duck blood is delicate and smooth, chopsticks are fragile, while fake duck blood is relatively rough and chopsticks are not broken.
2. After a piece of duck blood is drained with a napkin, if it becomes as tough as plasticine, it is fake duck blood.
3. Compared with fake duck blood, real duck blood is darker in color, more elastic and has a strong fishy smell. Generally speaking, fake duck blood is gelatinous in texture, not easy to break, similar in color to red bricks, and there are many honeycomb holes in the cross section.

Extended data:
According to the data in China Food Composition Table, the blood iron content of ducks is as high as 30.5~39.6 mg/100 g, but some ducks on the market are not so high. For example, the iron content of a duck's blood is only 2.42 mg/100 g, but the words "high iron content in fresh duck's blood" are written on the product package. Water is added in the process of making duck blood. The more water is added, the lower the iron content is.
In addition, some duck blood is impure, and chicken blood and pig blood with low iron content will be added. There is only one way to buy duck blood with high iron content: look at the nutrient composition table and choose a brand with high iron content.
