3.3.3. Effect on textural properties
The response surfaces of stickiness and hardness of rehydrated
rice samples were illustrated in Fig. 3. It appeared that the MWL
was the most dominant factor affecting on the stickiness and
hardness of rehydrated rice samples. Consumers normally
preferred the high stickiness and low hardness of rehydrated
brown rice whereas this characteristic could be obtained if high
MWL was applied. The chemical compositions, amylose and short
chains of amylopectin were mainly related to stickiness and hardness.
Since the microwave energy could weaken the interaction
between amylose and amylopectin and improve their dispersion as
