Example Embodiment
[0013] Example 1-Extraction of ostrich oil by conventional organic solvent method
[0014] Weigh 200 g of ostrich fat, place it in a 2000 mL round bottom flask, add petroleum ether (30-60) equivalent to 5 times the weight of the ostrich fat, and extract twice with reflux for 2 hours each. The extracts were combined, filtered with suction, and the filtrate was rotary evaporated at 40°C until there was no distilled liquid to remove petroleum ether solvent. The obtained extract is a yellow oil, and a flocculent solid gradually appears when placed at room temperature, and the color gradually becomes lighter, finally forming a pale yellow semi-solid shape, which becomes a white solid when cooled. The extraction rate is as high as 78%.
Example Embodiment
[0015] Example 2-Extraction of ostrich oil by supercritical extraction
[0016] Weigh 200g of ostrich fat and place it in the 1L extraction kettle of HA-220-50-06 supercritical extraction equipment (Huaan Supercritical Extraction Co., Ltd.), and adjust the supercritical equipment to meet the following conditions: extraction pressure: 20MPa, extraction temperature: 45 ℃, CO 2 Flow rate: 15L / h, separation I pressure: 8MPa, separation I temperature: 35°C, separation II pressure: 4-6MPa (according to the gas tank pressure), separation II temperature: 35°C, extraction time: 5h. After the extraction, the extract collected from Isolation I was a white solid paste, which was a white semi-solid when placed at room temperature, and a white solid when cooled. The extract can be directly used as the protective cosmetic base of the present invention without processing. The extraction rate is 71.6%.
Example Embodiment
[0017] Example 3-Extraction of Emu Oil by Supercritical Extraction
[0018] Weigh 250g of emu fat and place it in a 1L extraction kettle. Adjust the supercritical equipment to achieve the following conditions: extraction pressure: 25MPa, extraction temperature: 50°C, CO 2 Flow rate: 35L / h, separation I pressure: 8MPa, separation I temperature: 40°C, separation II pressure: 4-6MPa (according to the gas tank pressure), separation II temperature: 40°C, extraction time: 5h. After the extraction, the extract collected from Isolation I was a white solid paste, which was a white semi-solid when placed at room temperature, and a white solid when cooled. The extract can be directly used as the protective cosmetic base of the present invention without processing. The extraction rate was 20.6%.
