Anthocyanins provide real-time freshness indication, while their antioxidant and antimicrobial properties help delay food spoilage and enhance safety.

To address this, researchers have developed strategies such as blending, adsorption, microencapsulation, and electrospinning to enhance the stability and functionality of anthocyanins. Furthermore, this review critically discusses key barriers to commercialization, including high production costs, limited scalability, and regulatory uncertainty.
