Embodiment 1
[0058] Using a supercritical CO2 extraction device with an extraction kettle of 1L, put 300g of DHAGOLD seaweed raw material containing 37.9% oil into the extraction kettle for supercritical carbon dioxide extraction: the extraction pressure is 32MPa, the extraction temperature is 55°C, and the analytical pressure is 6.5MPa , the analysis temperature is 45°C, and the total extraction time after reaching the extraction pressure is 11 hours. 63.9 g of seaweed oil was co-extracted from the analysis kettle. The calculated total yield was 21.3%.
Embodiment 2
[0060] Using a supercritical CO2 extraction device with an extraction kettle of 1L, put 300g of DHAGOLD seaweed raw material containing 37.9% oil into the extraction kettle for supercritical carbon dioxide extraction: the extraction pressure is 15MPa, the extraction temperature is 45°C, and the analytical pressure is 5MPa. The analysis temperature was 35°C, and the total extraction time after reaching the extraction pressure was 8 hours. 49.8 g of seaweed oil was co-extracted from the analysis kettle. The calculated total yield was 16.6%.
Embodiment 3
[0062] Using a supercritical CO2 extraction device with an extraction kettle of 24L, put 6500g of DHAGOLD seaweed raw materials containing 37.9% oil into the extraction kettle for supercritical carbon dioxide extraction: the extraction pressure is 25MPa, the extraction temperature is 53°C, and the analytical pressure is 7MPa. The analysis temperature was 35°C, and the total extraction time after reaching the extraction pressure was 12 hours. 1339g of seaweed oil was co-extracted from the analysis kettle.
