摘要: In this study, we attempted to prepare chlorophyll-free young barley leaf extract powders using three different supercritical carbon dioxide (SCCO2) drying processes. The pure SCCO2 process for a methanolic solution resulted in ~30% increase the antioxidant (saponarin and isovitexin) content ~75% decrease chlorophyll compared solvent evaporation method. with ethanol-modified increased considerably completely removed chlorophylls. However, could not dry an aqueous ethanolic more than 30% water content. that employed periodic flush was found effectively
