摘要
介绍了目前用于测定食品体系中玻璃化转变温度的常用方法,包括差示扫描量热法(DSC)、动力机械分析法(DMA)、动力机械热分析法(DMTA)和核磁共振法(NMR)等,并列举了一些实例,同时对不同的方法进行了比较。
Methods used to measure the glass transition temperature (T_g) of food system were reviewed in this article including differential scanning calorimetry(DSC), dynamic mechanical analysis (DMA), dynamic mechanical thermal analysis (DMTA), nuclear magnetic resonance (NMR), and etc. Examples were cited in reviewing each method and the results were also compared.
