A flame retardant resin composition comprising: a hydrogenated petroleum resin, being a hydrogenated product of a polymer of an unsaturated hydrocarbon comprising at least one selected from the group consisting of an alicyclic compound having a five-membered ring and an aromatic hydrocarbon compound; a polyolefin; and an inorganic filler.

Flame-resistant resin composition, method for manufacturing same, and hydrogenated petroleum resin

The present invention provides a composition comprising a high content of highly pure, low-cost, and safe carotenoid and a method for industrially producing the same. The present invention also provides functional food, a pharmaceutical composition and a cosmetic product comprising such a composition. The present invention further provides a method for producing a composition containing at least 80% of carotenoid, which is characterized in treating a microorganism culture with extraction using a lower alcohol at 80&#xb0; C. at the lowest or a combination of water and a lower alcohol at 80&#xb0; C. at the lowest, and then washing and filtrating the precipitate obtained from the extract solution with a combination of a lower alcohol and water.

Method for production of carotenoid

Methods of obtaining a carotenoid-containing composition were developed, in which degradation of carotenoids is suppressed even though extraction and purification are performed on a culture of microorganism that produces carotenoids including astaxanthin by simple steps using a lower alcohol which is a conventionally known solvent, and the compositions have high astaxanthin content and contain highly pure carotenoids and also have satisfactory crystal properties. Further addition of a simple step that promotes isomerization of astaxanthin successfully improved the carotenoid yield.

Method for producing carotenoid-containing composition, and carotenoid-containing composition

The present invention provides a method for producing a carotenoid-containing composition, comprising the steps of: subjecting a culture of a carotenoid-producing microorganism to an extraction treatment using a water-soluble organic solvent; dispersing the resulting extract solution in water for micellization; heat stirring the resulting micellized solution in a solvent break the micelles and precipitate the carotenoid component of interest to obtain the precipitate; collecting and heat washing the precipitate with ethanol; and further subjecting the precipitate to pulverization/drying; and food, a pharmaceutical composition and a cosmetic product comprising the carotenoid-containing composition.
