Chewiness can be defined as the energy for masticating semisolid
sample (Huang, Kennedy, Li, Xu, & Xie, 2007). Fig. 3(F)
showed that with high power ultrasound (90 W) less energy was
needed to masticate the sample. This result may be explained by
the fact that high power acoustic energy destroyed the primary cell
wall and middle lamella more than that of the 30 W and 60 W
treatments.
