Crops that are grown for food are often vulnerable to diseases that cause the quality of the food to deteriorate over time. One important food crop is potatoes and these are particularly susceptible to bacteria and fungi that cause the potatoes to break down during storage or after they have been packed and dispatched to supermarkets. There are a number of organisms that can cause this breakdown and tests for these can be carried out individually using current technology. However, these tests look for one type of organism at a time and are often time consuming and expensive. We are developing a simple to use, fast and economical test that can detect the most important organisms in one sample at the same time in a few minutes. This means that the results are available quickly so prompt action can be taken as the potatoes enter storage or when they are washed prior to packing rather than waiting for lab results - by which time it is often too late to do anything about the spread to other batches. As well as testing the potatoes directly, another important area where this test will help is in monitoring the water that is used to wash the crops before packing. The amounts of water used are large and for economic and environmental reasons it makes sense to recycle this water. Companies have methods to recycle water and our rapid monitoring method will support the recycling process by providing a quick, easy and cheap tool to test when batches of wash water need to be replaced. Overall, the developments will result in less waste and potatoes that that can be stored for longer. Once successfully demonstrated for use with potatoes the technology will be developed for use in other food products.

作为食物而种植的作物往往容易受到疾病的影响，这些疾病会导致食物质量随着时间的推移而恶化。一种重要的粮食作物是土豆，这些土豆特别容易受到细菌和真菌的影响，导致土豆在储存期间或包装后分解并发送到超市。有许多生物体可以导致这种分解，并且可以使用当前技术单独进行这些测试。然而，这些测试一次只寻找一种类型的生物体，并且通常耗时且昂贵。我们正在开发一种简单易用、快速经济的检测方法，可以在几分钟内同时检测一个样品中最重要的微生物。这意味着可以快速获得结果，因此可以在马铃薯进入储存或在包装前清洗时采取迅速行动，而不是等待实验室结果-到那时，对其他批次的传播做任何事情都为时已晚。除了直接测试土豆外，这项测试将有助于另一个重要领域，即在包装前监测用于清洗作物的水。使用的水量很大，出于经济和环境原因，回收这些水是有意义的。公司有回收水的方法，我们的快速监测方法将通过提供一种快速、简单和廉价的工具来测试何时需要更换洗涤水批次，从而支持回收过程。总的来说，这些发展将导致更少的浪费和土豆，可以储存更长的时间。一旦成功证明用于马铃薯，该技术将被开发用于其他食品。
