Some suspect that it is caused by the addition of cottonseed meal to the feed, and some suspect that it is fake eggs. Today, let's look at things from a scientific point of view.
The Poultry Quality Supervision, Inspection and Testing Center of the Ministry of Agriculture and Rural Affairs, the Poultry Research Institute of the Chinese Academy of Agricultural Sciences, the School of Veterinary Medicine of Yangzhou University, the Poultry Product Quality and Safety Risk Assessment Laboratory of the Ministry of Agriculture and Rural Affairs, the Jiangsu Poultry Science Research Institute, and the Animal Husbandry and Veterinary Research Institute of Anhui Academy of Agricultural Sciences The egg yolk was found to be elastic at low temperature. The relevant experimental studies were published in the Chinese core journals "China Poultry" and "Animal Husbandry and Veterinary Medicine.
Because the average freezing point of egg yolk is -0.6 ℃, the set temperature of the refrigerator is generally 0-4 ℃, and the actual temperature will be biased. When the actual temperature is lower than 0 ℃, the eggs stored in the refrigerator may have this elastic phenomenon. It is suggested that the fresh eggs purchased by the public should not be close to the inner wall of the refrigerator when stored in the refrigerator, and can also be covered with plastic wrap outside the container. Take it out of the refrigerator and place it at room temperature for about 1 hour, it is also easy to break up. In winter, it is not in the refrigerator.
In 2018, CCTV also made a scientific clarification demonstration of a similar situation. You can search for "table tennis eggs are fake eggs? 315 to reveal the truth to you" to see the relevant video.
