Evidence Details

Thermodynamic evidence

AS-MUT：(Tc-To) = 15.55 °C，ΔH = 9.63 J/g

Thermodynamic evidence

BS-MUT：(Tc-To) = 16.98 °C，ΔH = 9.68 J/g

Source evidence

After microwave-ultrasound and toughening synergistic treatment, RC increased from 28.54% to 36.24% for A-starch granules and from 29.68% to 37.07% for B-starch granules compared with their native counterparts.

Equipment evidence

Starch samples were placed in a microwave ultrasonic ultraviolet synthesis and extraction instrument (XH-300UL, Beijing XiangHu Technology Development Co., Ltd., Beijing, China) and treated by microwaving at 500 W and ultrasonic at 500w, simultaneously.

Source evidence

In brief, the samples were treated by microwaving for 10 s at intervals of 110 s, the process above was repeated until microwaved for 50 s, and ultrasound treatment was performed throughout the period.

Source evidence

Compared with the starch samples with MU treatment, the percentage of RS in wheat A- and B-starch granules after MU-T treatment increased significantly, reaching 41.70% and 53.67%, respectively.
