​why are some egg yolks deep orange?


​​​​​Why Are Egg Yolks Yellow or Orange?

Egg yolks get their colour from carotenoids. C​​arotenoids are a class of more than 750 naturally occurring pigments synthesized by plants, algae, and photosynthetic bacteria ​​(1). These richly colored molecules are the sources of the yellow, orange, and red colors of many plants. ​If you haven’t guessed, carotenoids​ ​give ​colo​u​r to ​winter squash, carrots, corn, tomatoes, ​sweet potatoes and even ​canaries, flamingos, salmon, lobster, ​prawns.
