AIMThe aim of this interdisciplinary project is to study the interaction of human subjects with novel electronic freshness labels in the context of reducing food waste.PROBLEMThe freshness of packaged foods is estimated by the "useby" date that appears on the packaging. This date, however, does not reflect the actual state of freshness ofthe consumable, because it is dependent on, in addition to formulation and packaging, the storage and processing conditions. "Use-by" dates, which are approximations, lead to substantial food waste by consumers as they do not provide information concerning the actual freshness of the product in real-time.ELECTRONIC FRESHNESS LABELSThe Guder Research Group Imperial College has recently developed a new sensor technology (Barandun et. al., ACS Sens. 2019) that can measure food freshness in real-time and could replace the "use-by" dates to prolong shelf-life, reduce food waste and eliminate foodborne illnesses caused by spoiled foods. The sensors are printed paperbased electronic labels, that are applied to the packaging containing the fresh product, and detect gases released due to microbial spoilage of food in real-time. The sensors can be interrogated using near-field communication (NFC) enabled smartphones wirelessly and do not require additional hardware. We do not, however, currently know how/whether the sensors would be used by consumers when available.METHODOLOGYThis project has two Work Packages (WPs): WP1 involves engineering development and WP2 involves deployment of the technology to community fridges run by the Hubbub Foundation to study consumer behaviour and potential impact on food waste. WP1: Currently the sensing technology developed is at itsearly stages and requires extensive engineering development to create a complete system. For this, we will develop a mobile app, fabricate a quantitative wirelesssensor tag (currently the tags only provide on-off type freshness sensing but we would like to have a quantitative number that indicates freshness), apply hydrophobicmembranes to keep liquids away from the sensor surface and integrate into food packaging. WP2: The sensor tags developed will be applied to the food packages in the community fridges of the Hubbub Foundation. Hubbub will provide access to these facilities and allow us to study how consumers interact with these tags. We hope to understand whether the consumers choose to use the sensors for measuring freshness and how the freshness information impact their decisions.OUTCOMEThe primary outcome of this project will be the understanding of how consumers interact with the sensors and effects of spoilage information on consumer behaviour.A complete wireless NFC-enabled spoilage sensor tag, that can be integrated into food packaging, will also be produced.

AIMThe的目的是这个跨学科的项目是研究人类受试者的互动与新的电子新鲜度标签的背景下，减少food waste. Problem的包装食品的新鲜度估计的“useby”日期，出现在包装上。然而，该日期并不反映消费品的实际新鲜状态，因为除了配方和包装外，它还取决于储存和加工条件。“保质”日期是近似值，由于它们不能实时提供关于产品实际新鲜度的信息，因此会导致消费者浪费大量的食物。例如，ACS Sens. 2019），可以实时测量食物新鲜度，并可以取代“使用”日期，以延长保质期，减少食物浪费，消除由变质食物引起的食源性疾病。传感器是印刷的纸质电子标签，应用于包含新鲜产品的包装，并实时检测由于食品微生物腐败而释放的气体。传感器可以使用支持近场通信（NFC）的智能手机无线询问，并且不需要额外的硬件。我们不，但是，目前知道如何/是否传感器将被使用时，消费者。METHODOLOGYThis项目有两个工作包（WP）：WP 1涉及工程开发和WP 2涉及部署的技术，以社区冰箱运行的喧哗基金会，研究消费者的行为和潜在的影响食物浪费。WP 1：目前开发的传感技术还处于早期阶段，需要广泛的工程开发才能创建一个完整的系统。为此，我们将开发一个移动的应用程序，制作一个定量无线传感器标签（目前的标签只提供开关类型的新鲜度传感，但我们希望有一个定量的数字，表明新鲜度），应用疏水膜，以保持液体远离传感器表面，并集成到食品包装。WP 2：开发的传感器标签将应用于Hubbub基金会社区冰箱中的食品包装。Hubbub将提供这些设施的访问权限，并允许我们研究消费者如何与这些标签进行交互。我们希望了解消费者是否选择使用传感器来测量新鲜度以及新鲜度信息如何影响他们的决策。结果本项目的主要成果将是了解消费者如何与传感器进行交互以及腐败信息对消费者行为的影响。
