Does lead in preserved eggs harm people? What raw materials are used in the recipe for preserved eggs?

Preserved eggs are a type of processed egg food, also known as preserved eggs. Preserved eggs are named after the flower-like patterns on the egg white when it is peeled. Both chicken and duck eggs can be made into preserved eggs. Preserved eggs contain lead, so it is not advisable to eat too much. So are they harmful to the human body?

Is lead in preserved eggs harmful to humans?

Songhua eggs, also known as preserved eggs, contain an average of about 0.8 mg of lead per Songhua egg due to the use of lime and other ingredients during processing, which is more than double that of pickled duck eggs. Adults absorb less lead, while children absorb more. Long-term use of Songhua eggs with high lead content will affect children's growth and development. In particular, cracked Songhua eggs are more likely to cause lead pollution. Therefore, before eating, you should check whether the Songhua eggs have been cracked during production. The way to check is not to crack the eggshell too early, but to gently peel off the mud bran on the outside. After peeling, wash it with water to see if there are cracks in the eggshell. If there are cracks, it means that it has been cracked for a long time, so don't eat it.

However, lead-free eggs have been developed recently, using zinc oxide and copper oxide to replace lead oxide. This kind of Songhua eggs can be eaten without worries.

But when eating Songhua eggs, avoid eating Songhua eggs alone. The egg yolk and egg white contain a lot of soda ash. If you eat Songhua eggs alone, the soda ash inside will directly damage the stomach and intestines. You should add some vinegar when eating Songhua eggs to neutralize the alkalinity to avoid hurting the stomach and intestines.
