Abstract

Active food packaging is an innovative strategy to improve preservation and extend the shelf life of food products. In this context, aerogels, extremely lightweight and porous materials, have gained popularity for packaging development due to their ability to integrate active properties into their structure that enhance moisture control, controlled drug release, and barrier properties. This review explores emerging trends in the use of aerogels for active food packaging, focusing on the physical and functional properties of aerogels, their current applications in the food industry, and the challenges associated with their large-scale adoption. In addition, aerogels are compared to conventional packaging materials, highlighting their advantages in terms of sustainability and performance. Despite the numerous benefits and great potential of aerogels in the food industry, concerns related to cost, mechanical strength, and food safety persist. Recent developments in the production of aerogels and prospects for their use as an innovative material in packaging are addressed.

生物气凝胶作为活性食品包装材料：食品保鲜的新趋势。

活性食品包装是一种创新的策略，以提高保存和延长食品的保质期。在这种情况下，气凝胶这种极轻且多孔的材料，由于其能够将活性特性整合到其结构中，从而增强水分控制，控制药物释放和屏障特性，因此在包装开发中受到欢迎。这篇综述探讨了在活性食品包装中使用气凝胶的新趋势，重点是气凝胶的物理和功能特性，它们目前在食品工业中的应用，以及与它们的大规模采用相关的挑战。此外，气凝胶与传统包装材料进行了比较，突出了其在可持续性和性能方面的优势。尽管气凝胶在食品工业中有许多好处和巨大的潜力，但有关成本、机械强度和食品安全的担忧仍然存在。介绍了气凝胶生产的最新进展及其作为一种创新包装材料的应用前景。

期刊介绍： The journal Gels (ISSN 2310-2861) is an international, open access journal on physical (supramolecular) and chemical gel-based materials. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the maximum length of the papers, and full experimental details must be provided so that the results can be reproduced. Short communications, full research papers and review papers are accepted formats for the preparation of the manuscripts. Gels aims to serve as a reference journal with a focus on gel materials for researchers working in both academia and industry. Therefore, papers demonstrating practical applications of these materials are particularly welcome. Occasionally, invited contributions (i.e., original research and review articles) on emerging issues and high-tech applications of gels are published as special issues.
