"This meat is spoiled": Packaging tells you with fluorescent light. Kyushu University in Japan has developed a film that changes color and emits fluorescent light when freshness drops. A technology has emerged where the packaging uses light to let you know when you are unsure whether the meat in your refrigerator is still safe to eat. Researchers at Kyushu University in Japan found that the film changes color and emits ultraviolet light when the…
Smart packaging film 'lights up' under UV as meat loses freshness
Food spoilage causes chemical changes that are not always easy to detect by appearance alone. To provide a clearer indication of freshness and quality, researchers at Kyushu University have developed a smart packaging film that changes color and glows under ultraviolet (UV) light as meat loses freshness. Tested with refrigerated mutton, the film responds to compounds released during spoilage, offering two ways to track changes in food quality. T…
The deterioration of food causes chemical changes that are not always easy to detect by their appearance alone. To provide a clearer indication of freshness and quality, researchers at Kyushu University have developed an intelligent packaging film that changes color and shines under ultraviolet light [...]
Fresh check from the packaging: A novel film changes its colour when refrigerated meat releases spoilage during storage. In addition, it glows under UV light, in experiments with sheep meat about the sixth day. In the laboratory, the material also inhibited bacteria, but further tests are necessary for use in the supermarket. Fukuoka (Japan). Whether meat [...] The article Intelligent packaging film "lights under UV light when meat perishes firs…
A film has been developed that allows you to determine if meat has spoiled using only a UV lamp, without having to open the packaging. Researchers at Kyushu University in Japan have developed a casein-based dual-signal smart packaging film that detects the freshness of chilled lamb in real time. The research results were published in the international academic journal *Chemical Engineering Journal* on November 1, 2026. This film detects volati…
