the egg in the supermarket. How hard is the egg yolk as hard as rubber after cooking? A few days ago, Ms. Zhao bought 10 yuan of eggs in a large supermarket near Hong Jia building, Ji'nan, Shandong. Yellowish elastic, like a rubber ball. The big supermarket also sells this "rubber egg"? Can it be fake eggs? The experiment cooked egg yolk, like jelly Zhao said, bought a bag of ordinary eggs in the supermarket 10 days ago, and I felt that the taste was wrong. "After cooked, the protein has only a faint smell, the egg yolk is very elastic, and it doesn't have to be crushed without brute force." In order to find out, the reporter took several eggs and personally experimentation. This egg shell is dark yellow and has no red sensation. After cooking, the membrane between the egg white and egg shell is dry. The yolk looks like the ordinary yolk. It can be squeezed by hand and yolk is cake shaped without breaking. After loosening the hands, the yolk is restored to its original shape. Scoop out the yolk with a spoon, and the inside is jelly. To investigate the egg label address is actually the association, is this "fake egg"? The reporter saw on the egg packaging bag that the manufacturer is Ji'nan Rong Zhen commerce and Trade Co., Ltd. The reporters came to the address marked on the label, and several plaques in front of them wrote "the Ji'nan Christian Association", "Ji'nan economic school" and so on, and there were no signs of business companies. Reporters searched on the Internet and finally contacted a member of the Yang family who claimed to be a real business employee. She said that the location of the company is a section store, not the location marked, "there are associations, we have only one office." In January 9th, according to Yang's instructions, the reporter came to Duan's grain and oil wholesale market. The other side said that there was no eggs on the day. Since then, the reporter contacted the company's staff Mr. Ye, he said that the company really provided eggs for supermarkets, but Zhao bought the batch of eggs they did not supply. Then the reporter contacted Ms. Zhao to buy eggs in the supermarket, the staff said, their suppliers have many, but the label has been printed in Ji'nan Rong Zhen business limited company, "according to the day's supply records, egg suppliers for Ji'nan Hongguang economic and Trade Co., Ltd.".
Supplier
egg yolk hardening and feed related
14 day, the reporter contacted the supplier of the batch of eggs Ji'nan Hongguang economic and Trade Co., Ltd. A surnamed staff member said that their eggs were mostly from the farmers in Zhong Gong district. "Because of the cold winter, farmers fed some cottonseed cakes to the layers. Because cottonseed cake can enhance the immunity of layers and prevent colds to a certain extent. According to our understanding, the appearance of eggs should be related to the ingredients and proportions of layers. Mr. Shi said.
reporter contacted Professor Lin Hai of Shandong Agricultural University. He said cottonseed cake contains gossypol, and excessive consumption of animals may cause different toxic reactions. "The common cause of rubber egg is high content of gossypol in feed. Cottonseed cake is the residue after cottonseed oil extraction, which is rich in protein and is commonly used in chicken feed protein sources. He said that human consumption of meat related products or eggs and poultry products is less harmful, and the amount will cause dry heat and male permanent infertility or hypokalemia.
a reporter consulted a staff member of the Ji'nan quality inspection center. She said the appearance of "rubber eggs" was related to the low temperature and cold storage in winter, except for the excess cotton and meal in the feed. If the storage temperature is below 8 degrees Celsius for a long time, it will easily cause the loss of moisture in the eggs, which may cause the surface of yolk to be dark, but it will not affect the consumption.

Whether there is a problem of "rubber egg"? The reporter consulted with the staff of the safety supervision department of the livestock products of the Ji'nan Municipal Animal Husbandry Bureau. He said that the egg industry has only a standard of fresh eggs put forward by the Trade Department of the time in 1997. This standard defines fresh eggs, technical requirements, test methods, product inspection and marking, packaging and transportation. Regulations are made in storage and so on.
