Eating too many skin eggs can cause heavy metal element mercury poisoning?

1. Wrong

2. Correct

Correct Answer: Wrong

The content of heavy metals in traditional leather eggs is indeed higher, this is because in order to promote egg white coagulation and obtain a more beautiful pattern of pine flower crystals, the traditional leather egg processing formula adds yellow dan powder (lead oxide), which also leads to a higher content of lead in the leather eggs. There are also some small workshops that use industrial copper sulfate in order to save costs, which contains heavy metals such as arsenic and copper. Since lead is very harmful to the human body, people have found food-grade copper sulfate, zinc sulfate, selenium sulfite and other mixed salts to replace xanthan powder, made of low lead or lead-free leather eggs.
