Title
(EN) PROCESS FOR THE ISOMERIZATION OF LUTEIN
(FR) PROCEDE D'ISOMERISATION DE LA LUTEINE
Abstract
(EN)
A process to obtain a product with a high zeaxanthin content, to be used mainly as an ingredient in poultry feed to enhance the pigmentation of broiler chickens and egg yolk, by reacting at a controlled temperature and pressure, marigold $i(Tagetes erecta L.) meal or its oleoresin, or formulations containing lutein, with strongly alkaline aqueous solutions under controlled conditions, to isomerize the lutein into zeaxanthin in a product with a higher pigmenting activity.
(FR)
La présente invention concerne un procédé permettant l'obtention d'une teneur élevée en zéaxanthine, principalement pour l'alimentation de la volaille afin d'accroître la pigmentation des poulets à griller et du jaune d'÷uf. Le procédé consiste à faire réagir sous température et pression contrôlées de la farine de tagète (de l'espèce $i(Tagetes erecta L.)) ou son oléorésine, ou des formulations contenant de la lutéine avec des solutions aqueuses alcalines sous des conditions contrôlées, afin d'isomériser la lutéine en zéaxanthine, afin d'obtenir un produit présentant une activité pigmentaire plus importante.
