A method of pigmenting the egg yolk, integuments and/or subcutaneous fat of poultry and the meat and/or integuments of fish and crustacea involves including in the feed of the poultry, fish or crustacea one or more of the carotenoids 2'-dehydroplectaniaxanthin, 1-hydroxy-3,4-didehydro-1,2-dihydro-Ψ,Ψ-caroten-2-one, desmethylspheroidenone, spheroidenone, 5'-hydroxy-5',6'-dihydro-4'-apo-β-caroten-6'-one, 1'-hydroxy-3',4'-didehydro-1',2'-dihydro-β,Ψ-carotene-4,2'-dione and 5'-hydroxy-5',6'-dihydro-4'-apo-β-carotene-4,6'-dione. Also embraced by the invention are the pertinent carotenoid-enriched feed for poultry, fish or crustacea, the premixes for incorporation in such feeds and beadlets containing one or more of these carotenoids for incorporation in such premixes, the use of the carotenoids in the pigmenting method and the four new carotenoids of the seven aforementioned carotenoids. The new carotenoids can be produced by condensing in each case an appropriate aldehyde with 3-hydroxy-3-methyl-2-butanone, thereby forming the characteristic terminal 2-hydroxy-2-methyl-propionyl group.
在家禽的蛋黄、内脏和/或皮下脂肪以及鱼类和甲壳类动物的肉和/或内脏中添加色素的方法包括在家禽、鱼类或甲壳类动物的饲料中添加一种或多种类胡萝卜素 2'-dehydroplectaniaxanthin、1-hydroxy-3,4-didehydro-1,2-dihydro-Ψ,Ψ-caroten-2-one, desmethylspheroidenone, spheroidenone, 5'-hydroxy-5',6'-dihydro-4'-apo-β-caroten-6'-one、1'-羟基-3',4'-二氢-1',2'-二氢-β,Ψ-胡萝卜素-4,2'-二酮和 5'-羟基-5',6'-二氢-4'-阿朴-β-胡萝卜素-4,6'-二酮。本发明还包括用于家禽、鱼类或甲壳类动物的相关类胡萝卜素富集饲料,用于添加到此类饲料中的预混料,以及用于添加到此类预混料中的含有一种或多种此类类胡萝卜素的微珠,类胡萝卜素在色素添加方法中的使用,以及上述七种类胡萝卜素中的四种新类胡萝卜素。新类胡萝卜素可以通过在每种情况下将适当的醛与 3-羟基-3-甲基-2-丁酮缩合,从而形成特有的末端 2-羟基-2-甲基丙酰基来生产。
