Effects of cold air dehydration on icefish water dynamics and macromolecular oxidation measured by low‐field nuclear magnetic resonance and magnetic resonance imaging
Abstract We have used low‐field nuclear magnetic resonance (LF‐NMR) and magnetic resonance imaging to measure water dynamics and migration, color, and texture profile (TPA) of icefish dried with hot and cold air methods. Relaxation time of T 21 , T 22, and T 23 , and the peak area of A 22 and A 23 d...
