摘要
阐述了高聚物玻璃化转变理论及食品的玻璃态和玻璃化转变,介绍了玻璃化转变温度的测量方法和影响因素。食品是含有多种高分子物质的混合体系,它的玻璃化转变温度(Tg)影响到干燥食品的加工工艺和贮藏的稳定性。
The polymer＇s glass transition theory and food＇s glassy state and glass transition were expatiated in this paper. The measurements of sample＇ s glass transition temperature and its affection factors were introduced in the paper as well. Food＇s Tg could affect its processing and storage stability for it is a mixture of kinds of macromolecules.
