Abstract
Carotenoids are fat-soluble natural pigments with potent antioxidant and antibacterial properties, and their colors are sensitive to environmental pH changes (halochromic properties). Currently, natural carotenoids are utilized in the preparation of active packaging films, drawing significant attention in the field of food engineering for their potential application in smart packaging films. The use of carotenoids-based active films has shown promise in prolonging shelf life, but their application as pH-sensitive pigments in smart packaging for monitoring food freshness remains less established due to the several drawbacks (i.e., visual changes and others) discussed in this work. This critical review primarily summarizes the most used smart packaging materials, the halochromic properties of carotenoids and other pigments, and the applications of carotenoids-based films/bioplastics as pH-sensitive smart packaging for monitoring food freshness. Finally, we present to the readers our expert overview of the advantages and disadvantages associated with these natural pigments in the packaging sector.
期刊介绍:
Food packaging is crucial for preserving food integrity throughout the distribution chain. It safeguards against contamination by physical, chemical, and biological agents, ensuring the safety and quality of processed foods. The evolution of novel food packaging, including modified atmosphere and active packaging, has extended shelf life, enhancing convenience for consumers. Shelf life, the duration a perishable item remains suitable for sale, use, or consumption, is intricately linked with food packaging, emphasizing its role in maintaining product quality and safety.
