This review offers our opinion on current and future trends regarding nanoencapsulation interventions to extend postharvest shelf life of stored grains, fruits, and vegetables. Herein, we considered two major factors influencing postharvest shelf life for comments: aerobic food spoilage microorganisms and stored pests. Nanoemulsions, edible/active coatings, and nanopackaging loading essential oils as antimicrobial, antioxidant, or pesticide showed promising results in prolonged shelf life at room/cold storage without compromising quality, organoleptic properties, and postharvest physiology. Trends with nanoencapsulation using plant-based pesticides as agrochemical-free methods to keep produce fresh longer were commented as potential candidates for prolonging the shelf life of stored grains and fruits at the postharvest stage. Research with potential large-scale feasibility is intensive, but safety assessment is required and remains little explored.
本综述就纳米包封干预措施在延长储存谷物、水果和蔬菜采后货架期方面的当前和未来趋势发表了我们的看法。在此，我们考虑了影响采后货架期的两个主要因素以供评论：需氧食物腐败微生物和储存害虫。纳米乳液、可食用/活性涂层以及负载精油作为抗菌、抗氧化或杀虫剂的纳米包装，在室温和冷藏条件下延长货架期且不影响品质、感官特性和采后生理方面显示出了有前景的结果。使用植物源农药作为无农用化学品方法进行纳米包封以延长农产品保鲜期的趋势，被认为是采后阶段延长储存谷物和水果货架期的潜在候选方法。具有潜在大规模可行性的研究正在深入进行，但安全性评估是必需的且仍鲜有探索。
