鸡蛋是生活中最常见的食物之一,但对吃鸡蛋却存在很多误区:红蛋与白蛋由于红壳蛋色泽红润,因此,有人认为红壳蛋比白壳蛋营养价值高。这是错误的。蛋壳的颜色是蛋壳在生殖腔中形成时色素沉积在蛋壳中形成的,颜色因产蛋鸡的种类而异。科学家的试验还证明,把产红壳蛋和产白壳蛋的两种鸡在同等条件下喂养,产下的鸡蛋营养成分是一致的。
Eggs are one of the most common foods in life, but there are many misunderstandings about eating eggs: red eggs and white eggs Red eggs are richer in color than red eggs. Therefore, some people think that red eggs are more nutritious than white eggs. This is wrong. The color of the egg shell is formed when the egg shell is formed in the reproductive cavity. The color of the egg shell is formed in the egg shell, and the color varies depending on the type of laying hen. The scientists’ tests also showed that feeding two kinds of chickens with red shell eggs and white shell eggs under the same conditions gave the same nutritional composition.
