Detect Edible Oil Adulteration | Benchtop NMR | Oxford Instruments使用台式核磁共振波谱仪检测榛果油的掺杂

  • 在特级橄榄油中掺入低成本、低质的油一直是公众关切的问题。
  • 橄榄油和榛果油是极其相似的,这对于如FTIR在内的其他技术分析仪而言是极大的挑战。
  • 但他们的NMR谱线可以显示足够的差异,因此可以更加精确的检测掺杂的程度。

采用Pulsar检测一组30个纯橄榄油与榛果油,从各自NMR 谱线可计算获取各自单与多不饱和成分。

First Results from Pulsar published in TrAC

A recently published article in Trends in Analytical Chemistry (TrAC, published by Elsevier), co-authored by the Institute of Food Research, Norwich, UK, shows that Pulsar performs at least as well as FTIR for oil analysis. The results show that using chemometrics, hazelnut-oil adulteration of olive oil can be detected at 11.2%w/w.
