冷冻处理对糙米水分迁移以及微观结构的影响
The effect of freezing treatment on moisture migration and microstructure in brown rice
摘要
Abstract
The effect of freezing treatment on moisture migration in brown rice was studied using low-field nuclear magnetic resonance (LF-NMR) and the microstructure was also observed under a scanning electron microscope (SEM).After freezing,cracks appeared on the surface of brown rice with the increasing space of the starch granule.In addition,it took one-third of the time to reach the stable stage of proton density for frozen brown rice compared to the regular brown rice.Correspondingly,transverse relaxation time of bound water (T21) was in the same ratio of the regular brown rice.The result indicated freezing treatment could increase the water absorption rate of brown rice.关键词
