Applications of biotechnological tools in food preservation have shown promising results in minimizing food spoilage. Design and development of highly efficient food preservatives are one of the key success factors in this application field. However, due to the inherent shortcomings of the bulk forms of such preservatives, research was in progress to find suitable alternatives to replace conventional modalities. The intervention of nanotechnology has made this approach feasible in almost every aspect of food preservation. This interface domain of nanobiotechnology has been very well explored in the last few decades and vast literature has been reported. Researchers have developed efficient nanopreservatives (NPRs) for diverse applications. However, the literature available on nano-based food preservation is not inclusive of molecular perspectives involved in food preservation. There is a large knowledge gap in the interface domain concerning the physics of intermolecular and interfacial forces and nanotechnology which play decisive roles in designing edible coatings (ECs). There is an urgent need for identifying the nano and molecular level contributing factors for developing efficient NPRs. Moreover, it is imperative to understand the possible health impact of NPRs in public interest and concern. This review revisits the fundamental aspects of food preservation and navigates through the applicability, safety, molecular aspects and future direction of NPRs.
生物技术工具在食品保鲜中的应用在最大限度地减少食品腐败方面显示出了有希望的结果。设计和开发高效的食品防腐剂是该应用领域的关键成功因素之一。然而，由于这些防腐剂的散装形式固有的缺点，研究一直在进行，以寻找合适的替代品来取代传统的方式。纳米技术的介入使得这种方法在食品保鲜的几乎各个方面都变得可行。在过去的几十年中，纳米生物技术的这个界面领域得到了很好的探索，并且已经有大量的文献报道。研究人员已经开发出了用于各种应用的高效纳米防腐剂 (NPR)。然而，关于基于纳米的食品保鲜的文献并不包括涉及食品保鲜的分子观点。在界面领域，关于决定因素的分子间和界面力以及纳米技术的物理知识存在很大的空白，这些因素在设计可食用涂层 (EC) 方面起着决定性的作用。迫切需要确定纳米和分子水平的贡献因素，以开发高效的 NPR。此外，了解 NPR 对公众利益和关注的可能健康影响是至关重要的。本综述回顾了食品保鲜的基本方面，并探讨了 NPR 的适用性、安全性、分子方面和未来方向。
