Detection of spoilage in canned pasteurized milk using the radiographic imaging technique

After being packed into sterilized containers with a closed and rigorous process, pasteurized milk has ensured hygiene and safety factors. However, distortions can occur during storage and transportation, causing the container to open, allowing harmful microorganisms to enter and damage the product. This research proposes a radiographic imaging technique to detect and evaluate the spoilage of canned pasteurized milk. The X-ray images show that the milk cans, which were left open for three days at 300 K, appeared regions with abnormal density with the smallest detectable size from 100 µm or more. Density heterogeneity would be clearer in the following days and depending on the sample. An algorithm was developed to help identify spoilage products automatically with high accuracy. (author)
