The composite LF-NMR image reveals distinct variations in internal moisture distribution across the apple samples. The top-left and bottom-left images exhibit localized regions with higher signal intensity, indicating areas of concentrated moisture. These regions are surrounded by tissue with a more uniform signal intensity. The top-right image shows a central area with significantly reduced signal intensity, suggesting a dry core. The bottom-right image displays a more homogeneous signal intensity throughout, with minimal variation in moisture distribution. Patch morphology varies, with some areas showing distinct boundaries and others blending more gradually into the surrounding tissue.
