Abstract: Using nuclear magnetic resonance (NMR) studied spin-spin relaxation time (T2) in dough and bread in the producing process (mixing, fermenting, waking and baking). It existed a positive correlation between the spin-spin relaxation characteristic and molecular mobility. In the producing process, water mobility behavior of bond state and free state was different, besides, dietary fiber which treated with 140 MPa pressure will drink water, it can be change the storage property of bread.

Key words: bread, dietary fiber, NMR, water mobility
