Fast, accurate sensor to detect food spoilage
Organic Letters

Amid growing concern about outbreaks of food poisoning, researchers in South Carolina are reporting development of a new food freshness sensor, for fast, accurate detection of food spoilage. Their study is scheduled for the Aug. 16 issue of ACS Organic Letters, a bi-weekly journal.

In the study, John Lavigne and colleagues describe the need for better sensors that can detect food spoilage caused by E. coli, Salmonella, and other disease-causing bacteria. Existing methods, such as electronic noses and electronic tongues, require expensive equipment, are time consuming and involve complicated analyses.

In the study, they describe development of a polymer material that raises a red flag, changing color in the presence biogenic amines, compounds produced by the bacterial decay of food proteins. In laboratory tests, the polymer identified and distinguished between 22 different kinds of key food-spoilage amin
