| Abstract: | Corn - yellow pigment can be extracted from CGM by the supercritical fluid extraction (SFE) . The paper syste studied the influence of temperature, pressure, time, cosolvent solution on the extraction. Compared to the traditional solvent extraction a higher efficiency was obtained in the SFE. The yield of com - yellow pigment by SFE was 2. 2 times as much as in solvent extraction. The stability of corn - yellow pigment was also studied, it is sensitive to sunlight and should be preserved in dark at low temperature. |
