Abstract: This paper introduced the principle and examples of glass transition temperature(Tg) measured by nuclear magnetic resonance(NMR),and also the concept of the NMR state diagram and its applications in studying glass transition and the changes of the physicochemical properties of food before and after glass transition were introduced.

Key words: NMR, glass transition, Tg, NMR state diagram
