Abstract: In this study, the effect of freezing temperature during processing on water absorbability and distribution in konjac vermicelli was investigated using NMR. The results showed that the mobility behavior of bound and free water in konjac vermicelli was different during freezing. Konjac vermicelli frozen at -12 ℃ for 3 h during processing showed the highest water absorbability and water holding capacity during and after rehydration.

Key words: NMR, spin-spin relaxation time, absorbability, freezing temperature, konjac vermicelli
