Some of the more common diseases associated with seed contamination include salmonellosis, listeriosis, eschar, and food poisoning.
Which industrial pasteurization treatment to treat contaminated seeds while preserving its intrinsic qualities?
Industrial pasteurization is a heat treatment commonly used to destroy harmful microorganisms present in seeds while maintaining their nutritional and organoleptic qualities. The standard pasteurization treatment for seeds generally involves the application of heat at temperatures between 90-115°C for a fixed time depending on the nature and contamination of the seeds. However, it is important to note that this treatment can also alter some seed components, such as vitamins and enzymes, and should be done appropriately to minimize negative effects on seed quality. It is recommended that you consult a subject matter expert to determine the best pasteurization treatment for particular contaminated seeds.
