METHOD FOR PREPARING OIL-DISPERSIBLE CAROTENOID PREPARATION

摘要

Disclosed in the present invention is a method for preparing an oil-dispersible carotenoid preparation, comprising (by weight parts): mixing 100 parts of carotenoid microcapsule, 100-400 parts of vegetable oil and 0.1-1 part of oil-soluble antioxidant; and grinding the mixture in a colloid mill in a nitro—gen atmosphere and at 10-30° C. to obtain a uniform oil-dispersible carotenoid preparation, wherein the preparation contains 2%-14% carotenoid with an average particle size of up to 0.1-1 μm, and 100 parts of carotenoid microcapsule contains 10.5-35.8 parts carotenoid, 0.1-1 part of water-soluble antioxidant, and the remainder is a water-soluble colloid. The advantages of the present invention lie in that the oil-dispersible form has a high stability as the surface of the carotenoid particles is still protected with a dense water-soluble colloid, and that an oil-dispersible carotenoid preparation containing carotenoid with a content of up to 2%-14% and an average particle size of only 0.1-1 μm can be prepared.

1. A method for preparing an oil-dispersible carotenoid preparation, comprising (by weight parts):
mixing 100 parts of carotenoid microcapsule, 100˜400 parts of vegetable oil and 0.1˜1 part of antioxidant B, and grinding the mixture in a colloid mill in a nitrogen atmosphere at 10˜30° C. to obtain a uniform oil-dispersible carotenoid preparation, wherein average particle size of the carotenoid is up to 0.1˜1 μm; wherein the 100 parts of carotenoid microcapsule contains 10.5˜35.8 parts carotenoid, 0.1˜1 part of antioxidant A and the remaining is a water-soluble colloid; the antioxidant A is vitamin C, vitamin C sodium, iso-vitamin C or iso-vitamin C sodium; the antioxidant B is tocopherol, ethoxyquin, BHT (2,6-di-tert-butyl-4-methylphenol) or TBHQ (tert-butylhydroquinone).
