On April 18, Sina Weibo netizen "Mi Wei Air" reported to the official Weibo of the Evening News that at the end of last month, the family bought some chai eggs, and since last week, several egg yolks opened have been as hard as ping-pong balls, and they suspect that they have bought "fake eggs".
On April 18, the reporter contacted the netizen, who introduced: "More than 20 days ago, I bought some firewood eggs from the market in Wangdu County, specially for children and the elderly to eat, and put them in the refrigerator when I went home. I started eating and looking normal, during which an egg yolk appeared particularly hard, I thought it was broken, and I didn't care. This happened again last week, and four or five of these eggs were punched out in a row. I have bought it from this stall before, but this has never happened. ”
The reporter saw from the photos and videos provided by Mr. Li that the normal raw eggs collapsed into a flat circle after being put into the bowl. The "fake egg" egg whites that netizens suspect are fewer, and the yolk still maintains a swollen shape, and it cannot be stirred, and after clipping, it is a complete two pieces. According to him, "Beat the egg into a bowl, the egg whites are in normal condition, and the yolks are particularly hard. Use chopsticks to pinch open, the egg yolk is not broken, special porcelain, looking like a ping-pong ball, it feels like the egg yolk is particularly fake. At present, Mr. Li's family does not dare to eat the remaining eggs anymore, hoping that someone can help identify them."
On April 19, the reporter contacted the College of Animal Science and Technology of Hebei Agricultural University, and Chen Hui, a post scientist of the national layer industry technology system, told reporters: "From the photos and videos provided by netizens, I saw two white flocculent substances, that is, ties, which is an important basis for distinguishing between true and false, so it can basically be judged that it is not a fake egg." Making a realistic fake egg, from the eggshell, egg white to the yolk, is not technically simple, we have calculated, the cost of counterfeiting is very high. Therefore, most of the fake eggs spread on the Internet are technical training scams. ”
As for the reason why the yolk is hard, Chen Hui explains: "The egg looks closed, but there are many tiny pores on the eggshell. After a long time, the moisture will be lost and the yolk will dry easily. Moreover, there is also osmotic pressure inside the egg, and the yolk overflows and dries. Another case is the fertilized egg. Some of the eggs are fertilized eggs that hatch at the right temperature, a process that causes water loss and hardening of the yolk. ”
