摘要:

在面团中分别添加不同种类的抗性淀粉,利用核磁共振(NMR)技术测定面团弛豫特性。结果表明:添加不同种类的抗性淀粉玻璃态转变温度(Tg)基本没有发生变化;而随着添加抗性淀粉量的增加,Tg 有轻微的上升。置于玻璃态转变温度之下有利于延长面团保藏期。

关键词: 核磁共振, 抗性淀粉, 玻璃态转变温度

Abstract:

The relaxation characteristics of dough with addition of different types of resistant starches (RS) were investigated by low field nuclear magnetic resonance (NMR) technique. The glass transition temperature (Tg) of dough was not related to RS type. However, with the increase of RS content, the Tg slightly increased. Therefore the storage at temperature below Tg may be beneficial to prolong the shelf life of dough.

Key words: nuclear magnetic resonance, resistant starch, glass transition temperature
