Measurement of Water Movements in Food and Living Systems by Pulsed Field Gradient NMR
Hong, Y.S.;Lee, C.H.(Korea University, Seoul, Republic of Korea)E-mail:chlee@korea.ac.kr
Pulsed-field gradient NMR (PFG-NMR) is being widely applied to probe living tissues and biological cells structure for measurement of thermodynamic binding constants, membrane permeability and rate of transmembrane exchange processes. Water movements in biological systems and food matrices are important in the engineering aspect such as quality manipulation in food processing. The measurement of diffusion properties of water molecules in food systems is now possible using PFG-NMR, and the hydration properties and hydrodynamic properties of food materials can be accurately evaluated by this method.
