Abstract

DC60 (05/10/44) Method for enhancing coloration in egg yolks, skin and/or subcutaneous fat of poultry and meat and/or skin of fish and shellfish by incorporating one or more carotenoid esters into the diets of such poultry, fish and shellfish, where the carotenoids are carotenoid esters with formula (chemical formula) I, where R is methyl, C3-C16-alkyl, C3-C16-alkinyl or C5-C8-cycloalkyl. This invention also includes carotenoid-rich animal feeds for poultry, fish or shellfish, complete feed mixtures, pelleted feeds containing one or more of these carotenoid esters for incorporation into such complete mixtures, and the use of carotenoid esters in pigment enhancement methods. Some carotenoid esters of formula I are novel compounds and are composed in a specific manner. This invention describes a method for adding pigment to egg yolks, the skin and/or subcutaneous fat of poultry and meat and/or the skin of fish and shellfish by incorporating one or more carotenoid esters into the diets of such poultry, fish and shellfish. The carotenoids in question are carotenoid esters with the formula (chemical formula) I, where R is methyl, C3-C16-alkyl, C3-C16-alkinyl, or C5-C8-cycloalkyl. This invention also includes carotenoid-rich animal feeds for poultry, fish or shellfish; complete feed mixtures for incorporation into such feeds; pelleted feeds containing one or more of these carotenoid esters for incorporation into such complete mixtures; and the use of carotenoid esters in the pigment-enhancing method. Some of the carotenoid esters according to formula I are novel compounds and make up the following characteristics of this invention.
