Fresh fruits are prioritized needs in order to fulfill the required health benefits for human beings. However, some essential fruits are highly perishable with very short shelf-life during storage because of microbial growth and infections. Thus improvement of fruits shelf-life is a serious concern for their proper utlization without generation of huge amount of fruit-waste. Among various methods employed in extension of fruits shelf-life, design and fabrication of edible nanocoatings with antimicrobial activities have attracted considerable interest because of their enormous potential, novel functions, eco-friendly nature and good durability. In recent years, scientific communities have payed increased attention in the development of advanced antimicrobial edible coatings to prolong the postharvest shelf-life of fruits using hydrocolloids. In this review, we attempted to highlight the technical breakthrough and recent advancements in development of edible fruit coating by the application of various types of agro-industrial residues and different active nanomaterials incorporated into the coatings and their effects on shelf-life of perishable fruits. Improvements in highly desired functions such as antioxidant/antimicrobial activities and mechanical properties of edible coating to significantly control the gases (O₂/CO₂) permeation by the incorporation of nanoscale natural materials as well as metal nanoparticles are reviewed and discussed. In addition, by compiling recent knowledge, advantages of coatings on fruits for nutritional security during COVID-19 pandemic are also summarized along with the scientific challenges and insights for future developments in fabrication of engineered nanocoatings.

为了满足人类所需的健康益处，新鲜水果是优先需求。然而，由于微生物生长和感染，一些必需水果在储存过程中极易腐烂，保质期很短。因此，提高水果保质期对于正确利用水果而不产生大量水果废物是一个严重的问题。在延长水果保质期的各种方法中，具有抗菌活性的可食用纳米涂层的设计和制造因其巨大的潜力、新颖的功能、环境友好性和良好的耐用性而引起了人们的广泛关注。近年来，科学界越来越关注开发先进的抗菌食用涂层，以利用亲水胶体延长水果采后的保质期。在这篇综述中，我们试图重点介绍可食用水果涂层开发的技术突破和最新进展，通过应用各种类型的农工业残留物和不同的活性纳米材料纳入涂层及其对易腐烂水果保质期的影响。通过加入纳米级天然材料以及金属纳米粒子，对可食用涂层的抗氧化/抗菌活性和机械性能等高度期望的功能进行改进，以显着控制气体（O ₂ /CO ₂ ）渗透。此外，通过汇编最新知识，还总结了在 COVID-19 大流行期间水果涂层在营养安全方面的优势，以及工程纳米涂层制造未来发展的科学挑战和见解。
