摘要: 本研究应用NMR(核磁共振)和MRI(磁共振成像)技术研究了采摘后的草莓在保藏过程中水分损失和腐败过程。通过磁共振技术定量测量储藏过程中水分的损失与腐败过程,对采取热处理方法处理的草莓和室温保藏的草莓进行了对照,探讨了弛豫参数变化与草莓品质变化之间的相关性。对进一步研究草莓的腐败过程、腐败机理具有一定的指导意义。

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.
