Multinuclear spin relaxation and high-resolution nuclear magnetic resonance studies of food proteins, agriculturally important materials and related systems.
An overview of the applications of Nuclear Magnetic Resonance (NMR) techniques in Agriculture and Food Chemistry, covering high-resolution, solid-state, pulsed gradient and two-dimensional techniques is presented. The systems investigated by such techniques range from purified proteins to mixtures, starch granules and wheat grains. Both hydration and structural/composition approaches that employ NMR techniques are discussed from the point of view of applications rather than technique development. Hydration models derived from multinuclear studies are discussed for food proteins and enzymes. The role of protein-protein interactions in the analysis of the NMR results on hydration is also discussed. Amongst the food proteins considered are: wheat gliadins, glutenins, corn zeins, soy glycinins and conglycinins, as well as muscle proteins. Several new applications and new directions of development of NMR in Agriculture and Food Chemistry are suggested, and potential practical applications are pointed out.
