A STUDY OF ON PROCESSING PRODUCING THE SUPERCRITICAL CO2 EXTRACTION FROM JIAOGULAN (Gynostemma pentaphyllum)
Main Article Content
Abstract
To get the value of Jiaogulan, we researched supercritical CO2 extraction to diversify medical products for health. The material was treated by freeze-drying at a temperature of 300 C and a humidity of 9% to get high sensory quality. The optimization of saponin was carried out at a temperature of 500 C, pressure of 300,5 bar, and extraction time of 120 minutes. The antioxidant activity of the extract by the SFE-CO2 method was significantly high, with the inhibited capacity DPPH, hydroxyl, chelated Fe2+ (IC50 = 0,38 ± 0,01 mg/ml, 1,57± 0,07 mg/ml, 1,16 ± 0,05 mg/ml). The extract has low color change and retains its characteristic flavor and medicinal properties (saponins and polyphenols) during storage for three months at room temperature (28 ± 20 C, a humidity of 60 ± 5%).
