Do you want to pass off cow blood as duck blood? "It's like using duck meat as mutton, just for profit." Some insiders said that there are many merchants who pretend to be duck blood with cow blood in the Harbin market. The reporter learned from some wholesale markets in Harbin that it is also 311 grams, the price of cow blood is around 1 yuan, and duck blood is 5 yuan, which is very different. According to industry insiders, adding gelatin and carmine to cow blood products looks and tastes like duck blood, and some merchants add water to blend, which is why some duck blood is lighter in color after standing.

Duck blood will go bad if it is exposed at room temperature for a day or two. If you want to keep it for so long, you need to add preservatives. The preservatives can also make cow blood taste fresh and tender, more like duck blood. You can't confirm what is added without testing, but most of the fake duck blood seized by law enforcement agencies in the past has been added with formalin. According to doctors, formalin is easy to cause discomfort and lesions in esophagus and gastrointestinal tract. Long-term consumption will damage organs such as liver and may even cause cancer.

The genuine animal red is very rough. If it is cooked, only the mouth is slightly smooth, but the fracture is definitely uneven and rough. Some merchants bought it from meat joint factory or frozen meat factory, dried it, powdered it, and added various ingredients, such as 91% water, industrial pigments of chemical raw materials, preservatives, expansion agents, defoamers, coarse salt, a small amount of shaped gypsum powder, deadly formaldehyde and so on.

Some unscrupulous pig killers specialize in killing male sows, and the animals that are sick and dying are slaughtered and put on the market. This is as bad as the fake. They are real poisons. The blood tofu we usually eat also refers to duck blood, which can be made into various delicacies, suitable for all ages. Such as: duck blood vermicelli soup, hotpot, etc. However, a recent "poisoned duck blood" incident in Shiyan, Hubei Province, only to know that many merchants add the blood of pigs, chickens, cattle and sheep to the "poisoned duck blood" made of formaldehyde for personal gain.
