Abstract: The glass transition of food is one key to control food quality and stability. It is very important to truly determine the glass transition temperature of food to improve the conditions of food processing and storage. NMR/MRI has distinct advantages both in studying glass transition process and determining Tg. As an advanced analytic determination tool, NMR/ MRI will be widely used in food science field.

Key words: NMR, MRI, glass transition temperature, food, rapid measuring
