New "electronic nose" uses 16 sensors to detect food spoilage
Food spoilage remains difficult to detect before it becomes a health risk. Consumers often rely on appearance and smell other than expiry dates to judge whether products are still safe to eat, despite the limitations of those methods. Researchers at the University of California, Berkeley, have developed a sensor system designed to provide a more objective assessment. The technology combines miniature gas sensors with machine-learning software to…
Electric 'nose' can smell when your food's gone bad
Most of us have used the sniff test to decide whether a slightly expired bottle of milk or a week-old box of takeout is still good to eat. But while the human nose can be quite astute, it doesn't always catch everything. Each year, millions of people in the U.S. are sickened by food-borne pathogens that thrive in undercooked or spoiled food.
Science Writing, 17 Jun (EFE).- A chip with sensors from 16 materials inside a small closed camera and carbon nanotubes, that's basically the aspect of a new ‘electronic nose’ that can detect decaying foods and allergens of nuts with an overall accuracy of 92.6%.The device is the result of the collaboration of a team headed by the University of California at Berkeley (USA) that publishes its results in Science Advances.The chip generates unique …
Sniffing spoiled foods is not always as easy as it is with milk. An "electronic nose" can do this very precisely and even smells allergens.
