Lead-containing preserved egg technology has been the production of thousands of years of tradition, preserved egg new national standard will be the abolition of this millennium traditional craft ...... Yesterday, the reporter learned from the Municipal Bureau of Quality Supervision, preserved egg new national standards have been approved by experts, is expected to be formally implemented next year. At that time, all preserved eggs will have to adopt lead-free processing technology, otherwise they will not be allowed to go on sale.
Excessive lead in preserved eggs made by traditional technology
Some small workshop-style enterprises use the traditional process to produce preserved eggs, the brewing solution contains 0.2-0.4 of lead oxide, lead oxide can play a mature preserved eggs, will not appear solidified protein re-liquefaction phenomenon, to maintain all the characteristics of pine eggs. However, this often leads to a large amount of lead residue in preserved eggs. Although it is stipulated that the lead content should not exceed 2 mg/kg, the lead content of inferior preserved eggs is as high as 22 mg/kg, which greatly exceeds the national health standards and has great harm to the human body.
Excessive lead in preserved eggs can cause ADHD in children
"In recent years, in food quality inspections in various places, unqualified preserved eggs have always been on the list because of excessive lead content." According to the relevant person in charge of the Municipal Quality Supervision Bureau, the monitoring of heavy metals in the past five years has shown that the main food that is prone to lead pollution is preserved eggs, and its average content exceeds 1.2 to 8.0 times the national standard limit. Regular consumption of products with high lead content will cause the accumulation of lead in the human body, which will cause harm to the human nervous system, immune system, kidneys, etc., especially have a certain impact on children's cognitive and behavioral functions, which can cause children to suffer from ADHD.
Preserved eggs contain no more than 0.5 milligrams of lead per kilogram
The new standard requires lead-containing processing technology to be lead-free processing technology, strictly limits the lead content of preserved eggs, and requires that the lead content should be less than 0.5 mg/kg, which is three times lower than the 2 mg/kg lead content of preserved eggs required in the current Hygienic Standard for Egg Products.
It is said that lead-free process does not make the lead content in preserved eggs 0. The person in charge said that the lead-free process means that lead compounds are not used in the processing of preserved eggs, which does not mean that preserved eggs are completely lead-free, because fresh eggs, air, water and soil all contain a small amount of lead, and preserved eggs with a lead content of less than 0.5 mg per kilogram are safe for consumers to eat.
Expert advice: eating preserved eggs dipped in vinegar can "detoxify"
"Add some vinegar when eating preserved eggs, can minimize the absorption of toxic substances in the human body." Experts from the Municipal Bureau of Quality Supervision said that adding some vinegar when eating preserved eggs can not only neutralize the alkaline components in preserved eggs and improve the taste, but more importantly, acidic substances can minimize the absorption of toxic substances in the human body. For this reason, the expert suggests that citizens who love to eat preserved eggs must eat more foods rich in dietary fiber, such as celery, coarse grains, etc., which can absorb heavy metals in preserved eggs and reduce their absorption in the body. At the same time, but also eat more green leafy vegetables, these green leafy vegetables contain a lot of vitamin C, can promote the discharge of heavy metals in preserved eggs.
