Calculated hydrolysis index (HI) and predicted glycemic index (GI) for untreated and US treated resistant starch from lotus stem.
| Sample | Power | HI (%) | GI (%) |
|---|---|---|---|
| White bread | – | 50.07 ± 1.33f | 67.19 ± 0.96e |
| RS | – | 23.11 ± 1.09a | 52.39 ± 0.38a |
| URS1 | 100 | 26.34 ± 0.36b | 54.17 ± 1.08b |
| URS2 | 200 | 29.63 ± 1.21c | 55.97 ± 0.23b |
| URS3 | 300 | 32.09 ± 1.43d | 57.32 ± 1.26c |
| URS4 | 400 | 36.06 ± 0.13e | 59.50 ± 0.11d |
Where US represent ultrasonication; URS1, URS2, URS3 and URS4 represent resistant starch ultrasonicated at 100, 200, 300 and 400 W; HI is hydrolysis index; and GI is glycemic index. The results are the means of three replications ± standard deviations. Means in the column with different superscript differ significantly (p > 0.05).
