据科学家研究,在南、北极,一个普通的生鸡蛋,能整整维持三年不坏;而在地球的热带、亚热带,鸡蛋却很难保存半年。尤其是夏天,鸡蛋特别容易腐败。为什么气温升高鸡蛋容易变坏呢?这与鸡蛋本身抗菌能力下降有关。鸡蛋里里外外充斥着大量的细菌。当它在母体里孕育时,母鸡体内的细菌就跑了进去。所以即便是刚生下来的鲜蛋,里面也早有细菌了。至于鸡蛋排出体外之后,被污染的机会就更多了。诸如:通过排卵腔时要接触粪便;娩出体外要接触泥土;运输 According to scientists’ studies, a common raw egg in the south and the arctic can survive for three years without any damage. In the tropics, subtropics and eggs of the earth, it is hard to save for half a year. Especially in summer, eggs are particularly vulnerable to corruption. Why the temperature is easy to deteriorate the egg? This is related to the decline of the egg itself antibacterial ability. Egg inside and outside filled with a large number of bacteria. When it is conceived in the mother’s body, the bacteria in the hen’s body runs in. So even fresh eggs have just born, which also had bacteria. As for egg excretion, there is more chance of being contaminated. Such as: through the ovulation cavity to contact with excrement; delivered to the body to be exposed to the earth; transport
