Embodiment 1
[0034](1) Weigh 100 grams of Chlorella pyrenoidosa powder into supercritical CO 2 Extraction tank, close the extraction tank;
[0035] (2) Supercritical carbon dioxide extraction process parameters: pressure 35MPa, temperature 40°C, entrainer dosage 1.5ml ethanol / g material, CO 2 The flow rate is 20L / h, and the pressure and flow rate reach the predetermined value by adjusting the opening degree of the throttle valve and the speed of the carbon dioxide high-pressure pump;
[0036] (3) After reaching the set extraction time of 2.5 hours, the extract is collected, and the extracts in the first separation kettle and the second kettle are combined;
[0037] (4) Vacuum concentration (water bath 40° C.) extract to obtain an oily extract or freeze-dried powdery extract is the seaweed antioxidant active ingredient.
[0038] The material collected by the supercritical carbon dioxide extraction is concentrated in vacuum at low temperature, and the weight of the extract is measured, and...
