Introduction

These pigments, derived from various sources, are known for their remarkable properties, including antimicrobial, antioxidant, and anticancer effects, making them highly valuable across multiple industries such as food, cosmetics, and pharmaceuticals. Interestingly, microorganisms have emerged as a promising source for producing natural pigments. They generate a variety of colors, including prodigiosins, violacein, carotenoids, melanins, flavones, and quinones, along with specialized pigments like monascins and violacein, which are even found in red wine. Harnessing microbes for pigment production not only aligns with sustainability goals but also opens new avenues for innovative applications.

The food industry constantly faces the challenge of developing new colorants that are safe, cost-effective, and compatible with food flavors, nutritional values, and consumer preferences. While synthetic colorants have dominated the market due to their reliability and affordability, growing concerns about their potential health risks, such as carcinogenicity and allergenicity, have prompted a shift towards natural alternatives. Among these, microbial biocolors have emerged as a revolutionary solution, offering both safety and sustainability. This article explores the advantages, challenges, and diverse applications of microbial pigments, emphasizing their potential as an innovative and eco-friendly replacement for synthetic dyes.
