Colourants – efficient pigmentation for all needs

Strong, vibrant colours are often associated with quality and good health. Natural colour, such as that of egg yolk, poultry skin or salmon meat can be intensified by supplementing the feed with carotenoids. 

Why use colourants?

Colourants are yellow, orange or red pigments often obtained from natural sources such as Tagetes (marigold flowers), maize or lucerne. The level of supplementation can be adjusted to meet consumer preference.  

In addition to pigmentation, carotenoids also have numerous important physiological functions, acting e.g. as biological antioxidant and immunostimulant or maintaining intestinal mucosal barrier function when birds are exposed to immunological stress. 

Did you know?

  • Why leaves turn colour in autumn? The tree degrades and reabsorbs chlorophyll to save energy, and stores the molecules in the roots, branches and trunk until it is warm enough to rebuild the chlorophyll for the new leaves in Spring. The effect: as the chlorophyll degrades, the red, yellow or orange pigments become visible.
