Hunger and chronic undernourishment impact over 800 million people, which translates to ≈10.7% of the world's population. While countries are increasingly making efforts to reduce poverty and hunger by pursuing sustainable energy and agricultural practices, a third of the food produced around the globe still is wasted and never consumed. Reducing food shortages is vital in this effort and is often addressed by the development of genetically modified produce or chemical additives and inedible coatings, which create additional health and environmental concerns. Herein, a multifunctional bio‐nanocomposite comprised largely of egg‐derived polymers and cellulose nanomaterials as a conformal coating onto fresh produce that slows down food decay by retarding ripening, dehydration, and microbial invasion is reported. The coating is edible, washable, and made from readily available inexpensive or waste materials, which makes it a promising economic alternative to commercially available fruit coatings and a solution to combat food wastage that is rampant in the world.

易腐烂水果的多功能生物纳米复合涂料。

饥饿和长期营养不良影响了8亿多人，占世界人口的10.7％。尽管各国越来越多地通过追求可持续的能源和农业实践来努力减少贫困和饥饿，但全球生产的粮食仍有三分之一是浪费的，从未食用。减少粮食短缺在这项工作中至关重要，通常可以通过开发转基因产品或化学添加剂和不可食用的涂料来解决，这会带来更多的健康和环境问题。本文报道了一种多功能生物纳米复合材料，主要由鸡蛋衍生的聚合物和纤维素纳米材料组成，作为保鲜涂层在新鲜农产品上的保形涂层，通过延缓成熟，脱水和微生物入侵来减缓食物腐烂。涂层是可食用的，可水洗的，
