Proximate composition and antioxidant activities of F1 (control) and F3 (20 % roselle seed powder)
| Analysis | F1 | F3 |
|---|---|---|
| Ash (%) | 0.80 ± 0.03a | 0.88 ± 0.01b |
| Crude protein (%) | 5.9 ± 0.32a | 9.4 ± 0.32b |
| Crude fat (%) | 25.6 ± 0.51a | 26.6 ± 0.40b |
| Total dietary fibre (%) | 0.9 | 5.6 |
| Total carbohydrate (%) | 63.9 | 55.0 |
| DPPH radical scavenging capacity (%) | 82.2 ± 0.39a | 98.0 ± 1.36b |
| Total phenolic content (mg GAE/100 g seed) | 28.4 ± 2.28a | 60.2 ± 1.08b |
*Mean and standard deviation. Value at the same row with different superscript differ significantly (p < 0.05)
*Mean value for total dietary fibre (n = 2)
*Total carbohydrate is obtained by difference. Total carbohydrate = 100 % − (%moisture+ %ash+ %protein+ %fat+ % crude fibre)
*F1- 0 % roselle seed (control), F3- 20 % roselle seed powder were incorporated into cookie flour
