Ultrasound-assisted extraction (UAE) and microwave-assisted extraction (MAE) were applied to accelerate the extraction of Phycocyanin (P) from Arthrospira platensis. The compound is used as a natural antioxidant, anti-inflammatory, and anticancer compound in food and medicine, which is safer than synthetic antioxidants. The application of UAE and MAE was combined with natural deep eutectic solvent-citric acid fructose (NADES-CAF) as a green solution that is safe for the product and the environment to accelerate the extraction. This study aimed to evaluate the characteristics of NADES-CAF at various concentrations (1, 2, and 3%) and its performance in UAE and MAE, which were modelled using the Peleg kinetic approach. The characterization of NADES-CAF included density, viscosity, total dissolved solids (TDS), and electrical conductivity (EC). The results showed that higher concentrations of NADES-CAF increased the density, viscosity, EC, and TDS, thereby improving the performance of the solvent in extracting phycocyanin. Under ultrasonic and microwave waves, higher concentrations of NADES-CAF showed little change in extraction rate (0.0111–0.0411 mg/mL min) and maximum capacity (1.4353–6.4205 mg/mL). The extraction process followed the Peleg model, which showed an efficient and sustainable method for extracting phycocyanin from Arthrospira platensis. |
