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
