Protein, fat, sugar, inorganic salts, vitamins and other nutrients contained in eggs have changed during the incubation process, and most of the nutrients have been consumed by the development and utilization of embryos.
Even if you can leave a little nutrition, it is not as good as fresh eggs. Moreover, the eggshells of most king eggs have been broken, which is easy to be contaminated by bacteria, which is very beneficial to the reproduction of bacteria under the appropriate temperature.
Extended data:
Chicken embryo eggs contain many kinds of germs, such as Escherichia coli and Salmonella. Therefore, before eating, they must be heated at a high enough temperature to avoid gastrointestinal discomfort such as nausea, vomiting and diarrhea after eating.
Eggs may contain parasites. In fact, most nutrients such as protein, fat, sugar, vitamins or minerals contained in Wangwang eggs have been used by embryos during the incubation process, so they have no great nutritional value and cannot be compared with fresh eggs at all.
