If I knew its shelf life exactly, I would probably throw away less.\u201d<br \/>\nLauren Williams, from Splott, has said she stopped buying fruit and vegetables from supermarkets as they spoiled quicker and started buying from markets when she needed it.<br \/>\nShe said: \u201cMaybe I would bulk buy more if the dates were more accurate, rather than for each meal.<br \/>\n\u201cMaybe it would be useful to some degree for business, but ultimately nothing beats picking something up knowing it\u2019s still good or not.&#8221;<\/p>\n<h3><strong>\u2018Better access the quality\u2019 <\/strong><\/h3>\n<p>The team of researchers are now developing a system that measures the quality and freshness of produce, allowing better measures of shelf-life and help tackle food waste.<br \/>\nThrough their research they have identified the \u201cmolecular markers\u201d given off by rocket leaves before it goes off and want to apply this to other produce.<br \/>\nDr Hilary Rogers, one of the researchers working on the project, has said: \u201cIt\u2019s quite difficult to tell using our noses when something has spoiled.<br \/>\n\u201cWe are hoping that by creating a technique that can better assess the quality of the produce we will be able to reduce waste by allowing the industry to make better informed assessments of shelf-life.\u201d<br \/>\nDr Rogers said it would provide a more accurate shelf-life, however, changes in the conditions of how it is stored would affect that.<br \/>\nThe team includes Dr Hilary Rogers and Dr Carsten M\u00fcller of Cardiff University, Dr Geraint Morgan of Open University, and Dr Simon Sheridan from Applied Science and Technology Solutions.<\/p>\n<h3><strong>\u2018Cost-effective platform\u2019 <\/strong><\/h3>\n<p>The research is currently done through large-scale laboratory techniques called Gas Chromatography-Mass Spectrometry (GC-MS) \u2013 a way to separate and identify different chemical compounds.<br \/>\nThe team are now aiming to develop a system that uses this research in an easy and cost-effective way for the food and drink industry.<br \/>\nThe team are now working on a device that is small, portable and cost-effective so that it is useful for the suppliers and retailers.<br \/>\nDr Rogers, from Cardiff University, said: \u201cOur biggest challenge now is to take this complex technology and apply it to a cost-effective platform so that it can be used at different points in the supply chain, from production through to retail.\u201d<br \/>\nDr Morgan and Dr Sheridan have previously created a shoe-box sized version of a GC-MS for space missions such as the Rosetta Mission.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>NEW technology is being developed by researchers in Cardiff that can \u2018smell\u2019 when food is going off.
