Abstract

<p>NMR (Nuclear Magnetic Resonance) is an analytical technique that detects the magnetic moment of hydrogen atoms and other nuclei and is mainly used for structural analysis. On the other hand, TDNMR (Time Domain Nuclear Magnetic Resonance) is an analytical instrument that evaluates physical properties based on relaxation times. The relaxation time reflects molecular mobility, and it is possible to determine the amount of water and oil, evaluate physical properties such as hardness and softness of samples, and evaluate the particle size distribution and dispersibility of W/O and O/W emulsions and so on. This paper introduces examples of state analysis of foods, cosmetics, and other industrial products containing fats and oils using this analytical method.</p>
