| Sumario: | Colouration of textiles as well as food products with natural colorants is an interesting subject with respect to the growing eco-concern among the consumers. Several colorants are available in nature for textile colouration and are renewable, biodegradable, and eco-friendly. Being safe for human consumption, they can serve the dual purpose of also coloring food. Several such natural dyes are available. This review chapter deals with the chemistry, extraction, application, and colorimetric analysis of colorants derived from turmeric (root), annatto (seeds), and cochineal (insect) for use on both textiles and food products. |
