THE DEFINITIVE GUIDE: SUPERCRITICAL CO2 EXTRACTION PROCESS OF MILLET BRAN OIL
The millet bran oil extracted by supercritical extraction contains high unsaturated fatty acids, especially containing up to 67.8% of linoleic acid.
A complete guide to the CO2 extraction process
The most suitable conditions for supercritical co2 rectification of gluten oil are extraction pressure 30 MPa, extraction temperature 45 ° C, extraction time 2 h, co2 flow 50 kg / h, rectification column pressure 10 MPa, rectification temperature rectification I: 40 ° C, fine Distillation II: 45 ° C, rectification III: 50 ° C, rectification IV: 55 ° C.
By measurement, the supercritical extraction method extracts gluten oil containing high unsaturated fatty acids, especially containing up to 67.8% of linoleic acid. The physical and chemical indicators of extracting gluten oil by comparison of supercritical extraction method are better than the commercially available gluten oil. Therefore, fluid extraction-rectification by supercritical co2 is a better method for extracting gluten.
