| Popis: |
The extraction of bioactive compounds from the seaweed Gracilaria gracilis was optimized for food use using a Response Surface Methodology. Two designs, Central Composite Face-centered (CCD) and Box-Behnken (BBD) assessed the effects of extraction time, temperature, and seaweed-to-solvent ratio using water as the solvent. The extraction yield was assessed by Total Phenolic Content (TPC). BBD’s best model was a Reduced Quadratic (R2 = 0.9356), predicting 3.336 mg GAE/L at 74 °C in 1.4 h with a 1:75 ratio. CCD’s top was Reduced Cubic (R2 = 0.9091), forecasting 4.278 mg GAE/L at 46 °C in 1.1 h, the same ratio. The actual obtained TPC values were 4.35 mg GAE/L for BBD and 4.25 mg GAE/L for CCD. |
