Lead in preserved eggs is harmful to human body. Why is there lead in preserved eggs?

Preserved eggs contain lead because it uses brass powder in the process of making preserved eggs. Add lime, soda ash and a little yellow mud to wrap the eggs, and preserved eggs will appear in about a week or two. This kind of preserved egg is bound to contain some copper and lead.

Originally, preserved eggs made by this old-fashioned method are the same, but Taiwan Province Province has certain restrictions on this requirement. Lead should not exceed 2ppm, and copper should not exceed 8ppm, both of which are one kilogram. Then with the improvement of technology, many lead-free preserved eggs, preserved eggs and preserved eggs appeared. Actually, it's all the same Lead-free preserved eggs are not completely lead-free, but the content is very low, that is, 1 kg preserved eggs.

Preserved eggs are really delicious, and I like them myself, because they taste different from those cooked at home. Now save preserved eggs with completely different tastes, such as cucumbers or shredded tofu. Add some vinegar, some mashed garlic, some common garlic, chopped sesame oil, and a little sugar, and preserved eggs will taste very good. Even if you don't cook this cold dish, preserved eggs are used to cook porridge, and it is also a very good choice to make preserved egg lean porridge. Moreover, the price of preserved eggs is not expensive, about one yuan on average, because after all, it is processed by technology and is definitely more expensive than ordinary eggs.

At present, most preserved eggs sold online are lead-free. It's not that there is no money at all, but the content is very low, which has little impact on the human body. You can use it safely. Moreover, although it is delicious, it will not be eaten every day. If you eat it every day, you will feel uncomfortable. Eating it once in a while will feel quite fresh and delicious. You can choose to buy it online at an average price of one yuan.
