Yolk colour is often seen by consumers as an indication of egg quality, but many people don’t realise that yolk colour simply reflects the type of feed provided for the hens. Natural carotenes in green pasture and corn provide an excellent feed source. But large scale egg farms manipulate yolk colour by adding special manufactured pigment pre mixes to their poultry feed.
This enables brighter, more consistent yolk colour at lower inclusion rates, reducing overall pigmentation costs. Yellow egg colour technology is a significant part of the feed manufacturing process as producers try to enhance yolk colour in line with consumer expectations.
