Consumer preferences about the color of egg yolks vary by region. Egg yolk colors range wildly from soft yellow to dark orange depending on the hen's diet. In general, the more carotenoids a hen consumes in its daily diet, the darker the egg yolk color. Thus, carotenoids with strong antioxidant properties are often added to hen's daily diet to enhance nutritional value and deepen egg yolk color. We provide β-Carotene and Canthaxanthin FG product series that can be used as feed additives for hens to create more reddish orange egg yolk color.

The color of fish and shrimp is often considered an important indicator of quality and freshness which influences people's buying preference. Without carotenoid-rich food from nature, farmed salmon is naturally pale. Thus, carotenoids are often added to the fish feed in agriculture to deepen the color, making the farmed salmon look more "healthy and fresh" like wild salmon. Carotenoids are often added to ornamental fish feed to improve the skin and muscle color of ornamental fishes such as koi and goldfish as well. The brighter the color of ornamental fishes, the higher the commercial value. Our β-Carotene and Canthaxanthin FG product series can be used as feed additives in aquaculture to impart color to fish and shrimp.

Broiler skin color is considered an important indicator of quality, freshness and nutritional value of chicken in various countries. The carotenoids such as β-Carotene and Canthaxanthin are often added to feeds for skin pigmentation. In addition, carotenoids can also help with animal health, growth and reproduction. In particular, β-Carotene benefits the reproductive health of dairy cows and the immune system of hens. Our β-Carotene and Canthaxanthin FG product series can be used as feed additives to enhance the coloration of broiler skin for poultry and improve animal nutrition for livestock.
