Abstract
The present invention provides a carotenoids color preparation which itself has a high emulsion stability, so that there are no problems such as precipitation of an insoluble matter or neck ring formation even when this preparation is used in water-based products. The preparation is obtained by emulsifying a carotenoids color of natural origin, which has an acid value of 10 or less and an acetone-insoluble content of 5 wt % or less when adjusted so that the color value E10%1cm is 2550.
Claims21
A carotenoids color of natural origin, which has an acid value of 10 or less and an acetone-insoluble content of 5 wt % or less when adjusted so that the color value E10%1cm is 2550.
A carotenoids color emulsion preparation, which is obtained by emulsifying a carotenoids color of natural origin which has an acid value of 10 or less and an acetone-insoluble content of 5 wt % or less when adjusted so that the color value E10%1cm is 2550.
A method for manufacturing a carotenoids color emulsion preparation, comprising using a carotenoids color of natural origin, which has an acid value of 10 or less and an acetone-insoluble content of 5 wt % or less when adjusted so that the color value E10%1cm is 2550 as a raw material, and emulsifying the carotenoids color.
A method for stabilizing the emulsification of a liquid-form carotenoids color emulsion preparation, comprising using a carotenoids color of natural origin, which has an acid value of 10 or less and an acetone-insoluble content of 5 wt % or less when adjusted so that the color value E10%1cm is 2550 as a raw-material carotenoids color that is emulsified.
A use of a carotenoids color of natural origin, which has an acid value of 10 or less and an acetone-insoluble content of 5 wt % or less when adjusted so that the color value E10%1cm is 2550, for the manufacture of a carotenoids color emulsion preparation.
