Stable and high quality pigments are essential for required coloration
Supplementation of pigments to diets is crucial to obtain consumer’s preferred egg yolk and broiler meat colour, as animals cannot synthesize pigments themselves. However, for a controlled and uniform colouring of animal products, a high quality and stable pigment is essential. Natural pigments, like carotenoids, are largely used but have a poor stability and are highly sensitive to oxidants (e.g. oxygen), heat and humidity. The synthesized pigments, 10% canthaxanthin and 10% apocarotenoic ester (Orffa Additives BV, The Netherlands), have a high stability during storage as pure product, in premixes, and after pelleting (Figure 2). The spherical form of the granulates ensures an equal distribution of the pigment within the feed, contributing to a homogeneous mixture. These features of Canthaxanthin and Apocarotenoic ester from Orffa Additives BV enhance bioavailability and assure efficacy of the pigments (Table 2).
