The growing demand for sustainable and eco-friendly food packaging has prompted research on innovative solutions to environmental and consumer health issues. To enhance the properties of smart packaging, the incorporation of bioactive compounds derived from various natural sources has attracted considerable interest because of their functional properties, including antioxidant and antimicrobial effects. However, extracting these compounds from natural sources poses challenges because of their complex chemical structures and low concentrations. Traditional extraction methods are often environmentally harmful, expensive and time-consuming. Thus, green extraction techniques have emerged as promising alternatives, offering sustainable and eco-friendly approaches that minimise the use of hazardous solvents and reduce environmental impact. This review explores cutting-edge research on the green extraction of bioactive compounds and their incorporation into smart packaging systems in the last 10 years. Then, an overview of bioactive compounds, green extraction techniques, integrated techniques, green extraction solvents and their application in smart packaging was provided, and the impact of bioactive compounds incorporated in smart packaging on the shelf lives of food products was explored. Furthermore, it highlights the challenges and opportunities within this field and presents recommendations for future research, aiming to contribute to the advancement of sustainable and efficient smart packaging solutions.
对可持续和环保型食品包装的需求不断增长，促使人们研究创新解决方案，以应对环境和消费者健康问题。为了增强智能包装的性能，人们对源自各种天然来源的生物活性化合物的应用产生了浓厚的兴趣，因为这些化合物具有抗氧化和抗菌等功能特性。然而，由于其复杂的化学结构和低浓度，从天然来源中提取这些化合物具有挑战性。传统的提取方法通常对环境有害、昂贵且耗时。因此，绿色提取技术作为有前途的替代方法应运而生，提供了可持续和环保的方法，最大限度地减少了危险溶剂的使用并降低了环境影响。本综述探讨了过去 10 年中关于生物活性化合物的绿色提取及其在智能包装系统中的应用的最新研究进展。然后，提供了生物活性化合物、绿色提取技术、集成技术、绿色提取溶剂及其在智能包装中的应用的概述，并探讨了智能包装中添加的生物活性化合物对食品保质期的影响。此外，还强调了该领域内的挑战和机遇，并提出了未来研究的建议，旨在为可持续和高效的智能包装解决方案的发展做出贡献。
