Josh: 我认为首先要明确的一点是,无论鸡蛋的颜色如何,我希望这是真的,一种鸡蛋的营养价值并不一定比另一种更高。 商业生产的白色和棕色鸡蛋在营养方面是相同的。真正放养的鸡蛋,因为它们会吃草和昆虫等食物,所以它们的omega-3脂肪酸和维生素含量可能略高。 在美国,'放养'鸡蛋的标签没有受到监管,因此寻找经过认证的放养鸡蛋很重要。未清洗的本地鸡蛋可以不冷藏,但清洗后需要冷藏,因为清洗会去除保护蛋壳的蜡质层。 我吃过很多我朋友Justin的鸡蛋,从来没有洗过,也没有任何问题。 Chuck: 棕色鸡蛋并非天然的,白色鸡蛋也不是漂白的,只是鸡的品种不同导致蛋壳颜色不同。 鸡蛋颜色取决于鸡的品种,不同品种的鸡产不同颜色的蛋。鸡的耳垂颜色可以判断其产蛋颜色,白鸡产白蛋,有色鸡产有色蛋。 鸡蛋壳颜色是在输卵管的第四个部分形成的,此时蛋壳已经形成,然后一些鸡会在其上沉积色素。所有鸡蛋最初都是白色的,颜色是后来添加的。 两种色素,胆绿素和原卟啉,决定了鸡蛋颜色的多样性。胆绿素产生绿色和蓝色,原卟啉产生红棕色。 商业生产的鸡蛋需要清洗以去除细菌,但清洗会去除保护蛋壳的蜡质层,因此本地鸡蛋通常不清洗。洗过的鸡蛋需要冷藏保存。
