Fig. 1B illustrates the results of frequency sweep of sample gels.
The rheograms presented a similar pattern that G0 and G00 increased
gradually with the increasing frequency. The low dependence of G0
on frequency in all samples indicated that gels were formed with
high gel stability. Moreover, G0 and G00 increased rapidly with
increasing MS content. Gels with higher G0 exhibited more solid
phase, which showed higher rigidity, strength and elasticity in the
obtained gels (Li & Yeh, 2001; Suwannaporn et al., 2007). Amylose
content and starch type would affect the viscoelasticity of gels in
any case (Singh, Lin, Huang, & Chang, 2012). Retrogradation also
determined the difference in G0 , as degree of retrogradation was
positively related with gel firmness which was reflected in G0 (Lu
et al., 2009).
