Chemodosimeter in Polymer Films for the Selective Detection of Biogenic Amine Odorants

Summary: Public concerns over food safety are rapidly growing. Consumers want to be assured of the safety of food products. A small, reliable and low-cost “detector” that goes together with pre-packaged food products to demonstrate their safety in an eye-catching way is highly desirable. Rotting of meats and vegetables generates amines, which are key markers for food quality. At present, chromatographic determination is the most commonly adopted analytical approach for their detection. However, procedures involved are tedious and time-consuming.

Chemosensing is the detection of specific analytes by specially designed molecular sensors. Our invention will develop a series of cyano-bridged iron(II)-lanthanide(III) based complexes and poly-siloxane materials for the chemosensing of biogenic amines. The chemosensors will open up a new way for the monitoring of food safety in pre-packaged food products.
