From plant to fabric: Environmental opportunities associated with annatto dye for sustainable development in the textile industry

Coloration Technology, Volume 142, Issue 3, Page 333-353, June 2026.
Abstract Natural dyes are compounds that occur naturally in several organisms and are classified based on chemical structure and application method. The literature cites several natural dyes used in industrial transformation processes. Annatto dye is used in the food industry, and its biological pigment is extracted from the annatto seed. However, this
