For the GCWS starch, only after a few seconds of mixing, a sharp increase in the viscosity of the sample was observed (Fig. 2B).Water penetrated rapidly into the granules of GCWS starch and was absorbed by the starch molecules in the amorphous regions leading to a sudden increase in the viscosity (2350 cP . However the further increase in viscosity to 2530 cP that occurred more slowly is likely to be related to the penetration of water into the starch molecules
with a helical structure. This result is in agreement with Chen and Jane (1994b).
