Uhde High Pressure Technologies’ Post

Did you know that spores are highly resilient life forms that can contribute to food spoilage and foodborne illness? 🍄 🔬 Inactivating spores is one of the most challenging aspects of food preservation. The sensitivity of spores to pressure varies from species to species. Heat-resistant fungal (HRF) spores are a major concern for fruit processors. They can contaminate fruit juices and other products, resulting in substantial economic loss and food safety concerns. However, High Pressure Processing (HPP) can effectively address this problem. Research has shown that the application of hydrostatic pressure above 500-600 MPa, in combination with other factors such as temperature and duration, can significantly reduce the viability of heat-resistant fungal spores. This is because heat-resistant fungal spores are considered to be pressure sensitive. HPP can help ensure food safety and also extend the shelf life of these products. In contrast, bacterial spores often require a combination of heat and pressure to achieve inactivation. Therefore, HPP is crucial in controlling spore populations in the food industry when used with thermal processing. For more information, please contact Sergej Dimmel, HPP Production at the Uhde HPP Center in Quakenbrück. #thyssenkrupp #highpressureprocessing #uhde #hpp #spores
