Abstract

The present invention addresses the problem of providing a method for stabilizing a solid dye. This problem is solved by a method for stabilizing one or more types of solid dye selected from the groupconsisting of solid carotenoid dyes and solid curcumin dyes, wherein the method includes a step for mixing the solid dye with a lipophilic liquid in an amount of 200 parts by mass or less per 100 parts by mass of the solid dye.

Description

technical field [0001] The present invention relates to a method of stabilizing solid pigments and the like. Background technique [0002] Typical examples of solid pigments that have been widely used for coloring various foods and the like include carotenoid pigments and curcumin pigments. [0003] Carotenoid pigments (in this specification, sometimes simply referred to as "carotenoids") are oil-soluble pigments that exhibit yellow, orange, or red color, and are widely present in plants, animals, and microorganisms. Known examples include carotene pigments of carrots, paprika pigments, tomato pigments, and the like. [0004] Specifically, the main component of tomato pigment is called lycopene, which is known to exhibit a bright red color and to have an antioxidant function. These pigments have been widely used to color food. However, oil-soluble lycopene itself is not suitable for food manufacturing. Therefore, lycopene is used as an oil-in-water emulsion preparation i...
