Abstract: In this research water loss and decay process during storage by NMR(nuclear magnetic resonance) and MRI(magnetic resonance imaging) were studied. Through NMR technology, water loss and decay process were quantatively assayed. By comparing heat-treatment strawberry with strawberry under room temperature storage, the cofficient between change of relaxation parameters and change of strawberry quality was discussed. It is instructive to study furtherly decay process and mechanism.

Key words: NMR, strawberry, storage, sofening, decay
