摘要： Potato starch was treated by microwaving, toughening, and low-temperature aging to prepare resistant starch (RS). The functional properties of the resultant RS were evaluated and the effects of this microwave-toughening treatment (MTT) on the amylose content, RS content, digestive properties, pasting properties, morphological observation, crystal structure, and thermal performance of potato starch were determined. The optimal MTT parameters were microwaving at 300 W for 100 s, toughening at 55 degrees C for 16 h, and low-temperature aging at 4 degrees C for 18 h. After MTT, the amylose and RS contents of potato starch had increased from 26.08% and 11.54% to 35.06% and 27.09%, respectively. Furthermore, the pasting temperature increased from 66.8 degrees C to 76.36 degrees C, while the peak viscosity, trough viscosity, and final viscosity decreased significantly. After MTT, the potato starch surface had also changed significantly, and the crystallinity had increased from 32.43% to 51.36%. MTT starch had beneficial effects on fasting blood glucose, body weight, and organ index in mice. Furthermore, it had a protective effect on subcutaneous abdominal fat and liver tissue.
