Abstract

The study explores the potential of green extraction techniques—Microwave-Assisted Extraction (MAE), Ultrasound-Assisted Extraction (UAE), and Supercritical Fluid Extraction (SFE)—for obtaining natural food colorants from various plant materials. These methods were assessed based on efficiency, yield, environmental impact, and cost-effectiveness. MAE, UAE, and SFE demonstrated higher extraction yields and purity levels of bioactive compounds such as anthocyanins, carotenoids, and betacyanins compared to conventional methods. The environmental benefits of these green techniques include reduced energy consumption, minimal waste production, and the use of non-toxic solvents. However, technological barriers in scaling up, regulatory and safety considerations, and cost implications were identified as challenges. Future research opportunities lie in optimizing extraction conditions, improving scalability, ensuring regulatory compliance, and developing cost-effective solutions. The integration of these sustainable extraction methods into the food industry aligns with eco-friendly practices and meets the growing consumer demand for natural and safe food ingredients.

食品着色剂提取中的绿色技术：综合评述

本研究探讨了绿色萃取技术--微波辅助萃取（MAE）、超声辅助萃取（UAE）和超临界流体萃取（SFE）--从各种植物材料中获取天然食用色素的潜力。根据效率、产量、环境影响和成本效益对这些方法进行了评估。与传统方法相比，MAE、UAE 和 SFE 的提取率和生物活性化合物（如花青素、类胡萝卜素和贝特类）的纯度更高。这些绿色技术的环境效益包括降低能耗、减少废物产生和使用无毒溶剂。然而，扩大规模的技术障碍、监管和安全考虑以及成本影响被认为是挑战。未来的研究机会在于优化萃取条件、提高可扩展性、确保符合法规要求以及开发具有成本效益的解决方案。将这些可持续萃取方法整合到食品工业中，既符合生态友好型实践，又能满足消费者对天然安全食品配料日益增长的需求。
