Anthocyanins are natural pigments, known for their antioxidant, anti-inflammatory properties, and health benefits. One method to extract anthocyanins uses natural deep eutectic solvents (NADES). NADES are mixtures of two or more natural compounds that result in a liquid with a lower melting point than any of its individual components. NADES are nontoxic, biodegradable solvents that can be obtained from renewable sources, making them an attractive alternative to traditional solvents; therefore, they are known as the "21st century solvents." This review provides a comprehensive and critical assessment of the use of NADES as a sustainable solvent system for anthocyanins extraction. It also discusses the main properties of anthocyanins, NADES, process parameters, and economic and environmental analysis to efficiently extract anthocyanins. Current state of knowledge focusing on its applicability within the industrial context was evaluated and identified gaps in knowledge, highlighting its advantages and challenges to provide recommendations for future research.
花色苷是一种天然色素，具有抗氧化、抗炎特性和对健康有益。一种提取花色苷的方法是使用天然深共熔溶剂（NADES）。NADES 是两种或多种天然化合物的混合物，形成的液体熔点比其任何单一成分都低。NADES 是无毒、可生物降解的溶剂，可以从可再生资源中获得，因此它们是传统溶剂的理想替代品；因此，它们被称为“21 世纪溶剂”。本综述全面、批判性地评估了 NADES 作为花色苷提取的可持续溶剂体系的应用。它还讨论了花色苷、NADES、工艺参数以及经济和环境分析的主要性质，以有效地提取花色苷。评估了目前侧重于其在工业背景下适用性的知识现状，并确定了知识差距，突出了其优势和挑战，为未来的研究提供建议。
