Abstract

This book chapter explores the significance of natural red pigments, focusing on their sources, extraction methods, applications, challenges, and future prospects. Natural red pigments, derived from various plant, microbial, and animal sources, have been used historically in food, cosmetics, textiles, and pharmaceuticals due to their vibrant hues and potential health benefits. The chapter examines key natural red pigments, such as betalains, anthocyanins, and carotenoids, highlighting their distinct chemical properties and diverse uses across industries. The extraction processes, ranging from traditional methods to advanced technologies like supercritical fluid extraction (SFE) and microwave￾assisted extraction (MAE), are also discussed in-depth. These techniques not only improve efficiency but also address challenges related to sustainability, yield, and cost-effectiveness. Moreover, the chapter addresses the growing demand for natural colourants, driven by consumer preferences for clean-label and eco-friendly products, and the need to replace synthetic dyes that pose health and environmental risks. Despite their advantages, natural red pigments face challenges in terms of stability, cost, and sourcing. Issues like light degradation and temperature sensitivity impact their effectiveness, while the sourcing of raw materials raises ethical and environmental concerns. The chapter provides insight into innovative solutions, such as biotechnologicaladvancements, microbial fermentation, and synthetic biology, which offer promising alternatives for mass production. Looking ahead, the future of natural red pigments is promising, with advancements in biotechnology, sustainable sourcing, and consumer awareness driving innovation. The chapter concludes by exploring the potential for natural pigments in emerging markets, as well as the ongoing research needed to further develop cost-effective, stable, and scalable natural colourants. This work contributes to a deeper understanding of natural red pigments and their growing role in a sustainable, eco-conscious future.
