An object of the present invention is to provide zeaxanthin-enriched poultry eggs containing zeaxanthin at high concentrations. The present invention specifically relates to zeaxanthin-enriched poultry eggs obtained by feeding poultry with a poultry feedstuff containing zeaxanthin-producing bacteria.
The present invention provides a salmon flesh color improving method and a salmon flesh color improving feed which are usable for producing a salmon having a mild reddish orange flesh color close to the flesh color of wild fish, and a salmon and fish flesh thereof produced by such a flesh color improving method. The present invention also provides a method for producing a salmon having a mild reddish orange flesh color, comprising cultivating the salmon with a feed comprising a carotenoid colorant mixed therein, the carotenoid colorant comprising at least astaxanthin, phoenicoxanthin, canthaxanthin and adonixanthin.
A first method for refining dicyclopentadiene of the present invention is characterized in that the method separates and recovers dicyclopentadiene by distilling the crude dicyclopentadiene that contains dicyclopentadiene and is obtained by removing a C5 fraction and a BTX fraction from the reaction product obtained by dimerization reaction of the cracked gasoline by-produced in an ethylene plant that uses as feed stock a C2 fraction, a C3 fraction and a C4 fraction. A second method for refining dicyclopentadiene of the present invention is characterized in that the dicyclopentadiene-containing fraction refined by distillation is brought into contact with an inert gas or a hydrocarbon gas having 1 to 3 carbon atoms.
