Pig blood sold in the market actually contains almost no blood. Basically, it is cured with a glue and other chemicals, and then some pigments are added to blend. Some underground "dirty" workshops will also mix pig blood, cow blood, blood powder and starch for processing, which is called "mixed" pig blood.
Some even added the preservative "formaldehyde" which is forbidden by the state to prevent deterioration, which is more harmful to our health.
In 2009, Wuhan underground black workshop produced a large number of "artificial pig blood", which was solidified with a small amount of pig blood, formaldehyde, industrial salt, raw powder and dyes, and sold to bazaars and major hotels and restaurants, causing local citizens to be shocked.
At the end of May 2009, Wuhan dispatched hundreds of law enforcement officers to carry out an inventory, destroying a number of "artificial pig blood" black workshops, and many black-hearted workshop owners were under the control of the police.

Harm of artificial pig blood to human body;
Formaldehyde is a highly toxic substance, ranking second in the priority control list of toxic chemicals in China. Formaldehyde has been identified as a carcinogen and teratogenic substance by the World Health Organization. It is considered as an allergen and one of the potential strong mutagens.
Industrial salt often contains nitrite and so on. A large amount of intake will lead to hypoxia in the body, and it can also be converted into nitrosamines, a strong carcinogen, so everyone must pay attention when choosing.
Because fake pig blood usually needs to add a lot of pigment, if non-edible pigment is used, its toxicity is self-evident; If food pigments are used, there will be unsafe problems when they are added in large quantities. For example, using amaranth in large quantities will lead to calcium deposition in pelvis and kidneys.
