A comprehensive review on anthocyanin-rich foods: Insights into extraction, medicinal potential, and sustainable applications

Anthocyanins (ACNs) are natural pigments commonly found in plants which contribute to the vibrant colors of fruits, vegetables, and flowers. The present review aims to cover the ACNs field in terms of sources, extraction/ purification techniques, as well as characterization methods that are crucial for assessing their medicinal potential and sustainable applications. Characterization methods e.g. HPLC, UPLC-QTOF-MS, MS, and NMR are discussed as analytical tools for the identification and quantification of ACNs in various vegetable matrices. Their antioxidant, anti-inflammatory, antidiabetic, anti-cancer and cardiovascular properties are, also, highlighted. Besides, the use of ACNs as natural colorants, preservatives, and functional ingredients is discussed considering their impact on the food industry. Likewise, due to their anti-aging and skin-protective properties, their employment in the cosmetic field is reported making them appealing for skincare formulations. This review provides a comprehensive overview, emphasizing the ACNs versatility in medicine, food industry, and cosmetic field, fostering future research and innovation.
