A comprehensive study of natural and synthetic dyes: their properties, methods of preparation, and uses

Abstract

The use of natural dyes in the dying process was one of the oldest procedures used by the ancients. Obtaining dyes from natural sources means extracting them from plants and animals. Colors are derived from natural sources. Dyes can be divided into two categories: natural dyes and synthetic dyes. Synthetic dyes include saffron dyes and azo dyes, the latter being one of several types of organic compounds that are produced in large quantities through industrial processes. Dyeing is a process that involves the use of dyes in the dyeing process of textiles and food products. Fabrics are colored with different dyes for different types of fibers, while wool and silk are directly dyed with acidic and synthetic dyes. The food additives we are exposed to on a daily basis cause our bodies to produce toxins.

On the other hand, consumers have become more concerned about their food as a result of their understanding of the risks posed by these additives and the toxicity they contain. Dyes, natural dyes, azo dyes, and toxic dyes are just a few of the key terms.
