Now some profiteers make fake pig blood for profit, which poses a threat to consumers' health. Then how do they make these fake pig blood? Most of them are synthetic, and most of them are blended with blood powder, and then some additives are added, such as glass water, formaldehyde, hydrogen peroxide, alum and so on.

Then what harm will they do to the human body?

First, the coagulability of glass water will seriously harm the digestive tract and body fluids.

Second hydrogen peroxide is corrosive and harmful to gastric mucosa.

Third, formaldehyde contains carcinogens, and alum is also toxic.

The harm of fake pig blood is chilling, so many people no longer buy pig blood to eat.
