Modeling and Optimization of Supercritical CO2 Extraction of Natural Pigments from Black Rosehip Using Response Surface Methodology

Abstract

In this work, black rosehip was used as potent natural pigment source due to its anthocyanin content. To obtain these pigments, supercritical carbon dioxide extraction considered as a green extraction technique was employed. The effects of carbon dioxide pressure (150-350 bar), temperature (40-60°C) and co-solvent (ethanol) concentration (20-100%) on extraction of total anthocyanins were optimized using the Response-Surface Method according to the Box-Behnken model. Extraction of anthocyanins was successfully achieved when aqueous ethanol used as co-solvent. The most effective variables were co-solvent composition and pressure and temperature interaction (p<0.005). Optimum extraction conditions were elicited as the highest pressure (350 bar) and temperature (60°C) conditions and the ethanol concentration close to the center point values of 60% (54-55%). According to the results obtained, it was understood that the ethanol concentration should remain below 60%. In addition, extraction efficiency was found to be very low in processes using absolute ethanol. Finally; the model was validated. When the estimated total anthocyanin amount (R2 = 0.8936) was compared to the actual measured values, the values were found to be close to each other.
