The broader impact/commercial potential of this Small Business Innovation Research Phase I project will be better preservation of perishable food produce. The proposed new functionalized packaging film for perishable foods, incorporates innovative technologies to eliminate harmful microbes, lock in just-harvested aroma and taste, extend shelf-life from field to the kitchen table, and reduce food waste. These benefits will accrue to farmers and field workers, to shippers and truckers, to retailers who realize less produce waste, and o consumers. The proposed technology incorporates a novel nano-adsorbent metal organic framework (MOF) a molecular 'sponge' into a multi-layer packaging film which can deliver microbial protection, slow down the ripening process during shipment and deliver just-harvested quality in our fruits and vegetables. MOFs are a novel material technology which potentially could transform packaging from ?just plastic bags? to true active packaging. The technical objectives in this Phase I research project are to determine the technical feasibility to extrude a multi-layer film with the nano-adsorbent metal organic framework (MOF) material incorporated in a layer within linear low density polyethylene (LLDPE) film. This functionalized film structure will be selectively permeable via the embedded MOF structures to allow the exchange of gases, including ethylene, O2, CO2, other biologically active gases and certain antimicrobial compounds such as chlorine dioxide. Control of fruit and vegetable respiration (O2/CO2 balance), control endogenous and exogenous ethylene, and the delivery antimicrobial gases via MOFs could be the single most important recent technology breakthrough that allows producers in distant markets to delivery fresh produce. This research project will seek to identify MOFs with the appropriate gas exchange properties, heat stability in the blown film extrusion process and proper orientation within the film structure. Collaborative research is needed to select likely MOF candidates, to incorporate these MOFs in films extruded on pilot scale equipment, and to characterize effectiveness at a university-based postharvest laboratory to enable rapid technology development, impartial assessments, and effective reduction to practice.

这项小企业创新研究第一阶段项目的更广泛影响/商业潜力将是更好地保存易腐食品。提议的用于易腐食品的新型功能化包装薄膜，采用创新技术来消除有害微生物，锁定刚刚收获的香气和味道，延长从田间到厨房餐桌的保质期，并减少食物浪费。这些好处将惠及农民和田间工人、托运人和卡车司机、意识到产生废物较少的零售商以及消费者。该技术将一种新型纳米吸附剂金属有机框架（MOF）——一种分子“海绵”——整合到多层包装薄膜中，可以保护微生物，减缓运输过程中的成熟过程，并保证水果和蔬菜的刚收获质量。mof是一种新型的材料技术，有可能改变传统的包装方式。只是塑料袋吗？真正的活性包装。第一阶段研究项目的技术目标是确定在线性低密度聚乙烯（LLDPE）薄膜中加入纳米吸附性金属有机框架（MOF）材料的多层薄膜挤出的技术可行性。这种功能化的薄膜结构将通过嵌入的MOF结构选择性地渗透，从而允许气体交换，包括乙烯、O2、CO2、其他生物活性气体和某些抗菌化合物，如二氧化氯。控制水果和蔬菜呼吸（O2/CO2平衡）、控制内源性和外源性乙烯以及通过mof输送抗菌气体可能是最近最重要的技术突破，它使遥远市场的生产者能够输送新鲜农产品。该研究项目将寻求确定具有适当的气体交换性能、吹膜挤出过程中的热稳定性和膜结构内适当取向的mof。需要进行合作研究，以选择可能的MOF候选物，将这些MOF纳入中试规模设备挤压的薄膜中，并在基于大学的收获后实验室中表征有效性，以实现快速技术开发，公正评估和有效的减少实践。
