Changes in the total chemical composition of Centaurea thracica inflorescences.
| Indicators | June | September |
|---|---|---|
| Proteins, % | 8.7 ± 0.1 * | 7.4 ± 0.2 |
| Oil, % | 2.0 ± 0.1 | 1.7 ± 0.1 |
| Carbohydrates, % | 72.3 ±0.6 | 77.2 ± 0.7 |
| Crude fibers, % | 28.7 ± 0.4 | 35.8 ± 0.3 |
| Ash, % | 4.5 ± 0.1 | 4.2 ± 0.1 |
| Moisture, % | 12.5 ± 0.1 | 9.5 ± 0.1 |
| Energy value **, kJ/100 g (kcal/100 g) | 1453 (342) | 1503 (354) |
* The samples were analyzed in triplicate (n = 3), and the results were expressed as mean and standard deviation. ** The energy value (EV) in kJ/100 g (kcal/100 g) was calculated as follows: EV = % proteins × 17 (4.0) + % carbohydrates × 17 (4.0) + lipids × 38 (9.0).
