绿色植物在胃肠道中的消化产生叶绿素降解产物，导致食物和粪便发出高荧光。这种特性被用于开发和建造仪器，以非侵入性地检测真实的时间内肉类样品上的微量粪便。肉类产品上的粪便是食源性病原体的主要来源，如大肠杆菌O157：H7和沙门氏菌。这项新技术提供了一个快速和准确的替代目视检查的做法，并增加了更耗时的生物测试方法。这项创新可以帮助肉类加工商和政府检查员努力为消费者提供安全和健康的食品。
Digestion of green plants in the gastrointestinal (GI) tract produces degradation products from chlorophyll that cause ingesta and feces to be highly fluorescent. This property was exploited for development and construction of instruments to noninvasively detect minute quantities of feces on meat samples in real time. The presence of feces on meat products is a primary source of foodborne pathogens, such as Escherichia coli O157:H7 and Salmonella. This new technology provides a rapid and accurate alternative to the practice of visual inspection and augments more time-consuming biological testing methods. This innovation can assist meat processors and government inspectors in their efforts to provide safe and wholesome food to consumers.
