Research Abstract |
Naturally occurring dyes are generally superior in safety but inferior in stability. The stability of anthocyanin, one of typical natural dyes, was able to be enhanced by making composites with several inorganic host materials, such as mesoporous silicas and layered compounds. When the inorganic host was properly modified with surfactants to become hydrophobic, the lipophilic natural dye such as beta-carotene can be effectively incorporated and stabilized by the complexation. The composite materials between the natural dye and the inorganic hosts were able to be prepared in some cases by simply mixing the powders of the dye and the host materials.
