Canthaplus 10% ® -- Canthaxanthin 10% Feed Grade

Carotenoids are used to colour food products of animal origin. In order to meet market needs and considering the inherent variations of the diets in terms of colouring agents, the feed industry adds colouring agents to salmonid feed (to colour the flesh), to laying hens diet (to modify the yolk pigmentation) and, in some areas, to chicken diet (to modify skin pigmentation). Canthaxanthin is one of the carotenoids authorised for use in animal feed as a colouring agent in poultry feeds and fish feeds in accordance with Council Directive 70/524/EEC as E-161g.

good absorption characteristics.

 

 

 

Use of Canthaxanthin in Poultry

Canthaxanthin is used for egg-yolk and broiler pigmentation,
as the red component of the yolk colour, and in foods and
cosmetics requiring a more orange-red hue.

 

Use of Canthaxanthin in Aquatic

Market requirements varied over time. The recent trend has been towards increased pigmentation. Between 1976 and 1982, fish flesh contained up to 2.5 mg carotenoids (mainly added canthaxanthin) per kg of flesh in Norwegian farmed Atlantic salmon. Then, between 1982-1988, the concentrations increased up to around 3-5 mg/kg.
