- Abstract
- The ability to acquire images of intact microstructures of food products is of great benefit to both structural and functional studies related to food processing and preservation. X-Ray microCT is particularly well suited for this purpose as it benefits from both its nondestructive nature as well as the high resolution output. However, fundamental limitation of X-rays results in the inability of CT systems to distinguish between materials with similar atomic composition. In the context of food microstructure studies, this results in the inability to separate otherwise distinctive structures such as dense cell clusters in tissues of fruit or meat. While the medical imaging field have been developing and utilizing contrast agents to combat this limitation, these agents are seldom used outside of medicine. This study explores and demonstrates the value of utilizing contrast enhancing agents for purposes of both cell cluster separation and structure labelling. With the use of commercially available contrast enhancing agents in conjunction with optimized delivery methods, we demonstrate the significant improvement in both cellular and structural separation of both fruit and meat tissue samples. The enhanced separation allows additional software processing in which more accurate 3D models of intact structures can be produced, and thus provide a better foundation for downstream analysis and modeling.
