Researchers at UC Berkeley have developed a device, dubbed an “electronic nose,” capable of rapidly detecting spoiled food. The technology, detailed in *Science Advances*, utilizes a sensor array to identify volatile organic compounds (VOCs) released by decaying produce. This allows for quick assessment of food freshness without destructive testing. The device aims to reduce food waste by providing a non-invasive method for quality control throughout the supply chain. Scientists believe this technology could be implemented in homes, supermarkets, and food processing facilities. The collaborative research demonstrates a significant advancement in food safety and preservation techniques.
