Recent advances in improving anthocyanin stability in black carrots

Le résumé fourni par la source

This review focuses on the methods of enhancing the stability of black carrot anthocyanins, which are susceptible to degradation due to temperature, pH, light, and oxygen. These anthocyanins are valued for their health benefits and blue-violet color, but their instability limits their application in the food industry. It is hypothesized that implementing advanced stabilization techniques can significantly improve the stability and usability of black carrot anthocyanins. Key methods to improve anthocyanin stability, including encapsulation, co-pigmentation, and acylation, are comprehensively reviewed. Encapsulation techniques such as spray drying, freeze drying, and liposomes have shown effectiveness in protecting anthocyanins during food processing and storage. Co-pigmentation with non-anthocyanin phenolics and using whey proteins significantly enhance thermal and pH stability, thereby improving color retention. Additionally, innovative strategies like genetic modification and nanoencapsulation have demonstrated potential in further stabilizing anthocyanins by enhancing their structural resilience and bioavailability. These innovative approaches represent a significant advancement in the ability to maintain the integrity of black carrot anthocyanins. Advanced techniques for preserving the functional properties and nutritional benefits of black carrot anthocyanins facilitate broader use in health-oriented food products. Combining these modern methods is essential for optimal stability, and further research is needed to optimize these techniques.
