Where WAC is the water absorption capacity; OAC is the oil absorption capacity; US is ultrasonication; URS1, URS2, URS3 and URS4 represent the resistant starch ultrasonicated at 100, 200, 300 and 400 W. The results are the means of three replications ± standard deviations. Means in the row with different superscript differ significantly (p > 0.05).
