ABSTRACT
Synchrotron radiation (SR), which is the electromagnetic radiation generated by charged particles accelerated in a magnetic field, can be used to observe materials and their functions at the nanoscale. SR is a powerful and advanced light source with a wide wavelength, ranging from infrared (IR) to X-ray. Fish are usually distributed under refrigerated or frozen conditions after harvesting, with some being processed for the production of a variety of seafood products, including surimi, kamaboko, and dried and salted fish. SR light sources can be divided into three categories according to their energy: low energy, intermediate energy, and high energy. XRCT is a method of three-dimensional imaging in which X-ray transmission images are acquired of a material from various angles and reconstructed from the resulting two-dimensional projection image, using the difference in X-ray transmission at each point in the material as contrast.
