Embodiment 1

[0019] Put 200g of minced meat-like ostrich fat into the barrel of the supercritical extraction device (HA220-50-06 type), and then put it into a 1L extraction kettle. After carefully checking the extraction system, turn on the CO 2 Cylinder, through the condenser fresh CO 2 Liquefaction, liquid CO 2 Through the high-pressure pump, mixer and heat exchanger into a supercritical fluid, the entire extraction system is replaced by CO 2 Replace and fill. Set the extraction unit CO 2 The flow rate is 20L / h; the extraction pressure is 15-20MPa and the temperature is 36-40°C; the pressure of separator 1 is 8MPa and the temperature is 35°C; the pressure of separator 2 is 6MPa and the temperature is 40°C. Continuous dynamic extraction for 2 hours, during which the white oily extraction product was often collected from the outlet at the bottom of the separator. Weigh the extract, a total of 74g, and the extraction rate is 37.0%.

Embodiment 2

[0021] With reference to Example 1, 200g minced meat-like ostrich fat is put into a 1L extraction kettle, and the whole extraction system is heated with CO 2 Replace and fill. Set the extraction unit CO 2 The flow rate is 20L / h, and the co-solvent ethanol flow rate is 0.5L / h; the pressure of the extraction kettle is 15-20MPa, and the temperature is 40-45°C; the pressure of separator 1 is 8MPa, and the temperature is 35°C; the pressure of separator 2 is 6MPa, and the temperature is 40°C. Continuous dynamic extraction for 2 hours, during which the liquid extraction product was often collected from the outlet at the bottom of the separator. The product was collected, ethanol in the product was removed, and dried to obtain 86 g of extract product with an extraction rate of 43.0%. Compared with Example 1, the extraction rate improves, but the product color index decreases.

Embodiment 3

[0023] With reference to Example 1, 200g minced meat-like ostrich fat is put into a 1L extraction kettle, and the whole extraction system is heated with CO 2 Replace and fill. Set the extraction unit CO 2 The flow rate is 20L / h; the extraction pressure is 25-30MPa and the temperature is 50-55°C; the pressure of separator 1 is 8MPa and the temperature is 50°C; the pressure of separator 2 is 6MPa and the temperature is 55°C. The continuous dynamic extraction was carried out for 3 hours, during which the oily extraction product was often collected from the outlet at the bottom of the separator. Weigh the extract, a total of 101g, and the extraction rate is 50.5%. Compared with Example 1, the extraction rate improves, but the product color index decreases.

Abstract

The invention provides a method for preparing ostrich oil. An ostrich oil product is obtained by supercritically extracting ostrich adipose tissue as a raw material and CO2 as an extracting agent at the extracting temperature of 45-55 DEGC, the extracting pressure of 20-25MPa, the separating pressure of 4-9MPa and the separating temperature of 40-60 DEGC. The invention extracts the ostrich oil by supercritical fluid and has the advantages of low temperature and no poison and pollution. The method can more favorable maintain the active component and the unique penetrability of the ostrich oil, has simple method, convenient operation, short production time, no residual solvent, environmental-friendly production process and industrial application prospect, more favorable prevents the oxidation and decomposition of an unsaturated fatty acid component, maintains the active component and the favorable penetration characteristics of the ostrich oil and leads the materials not to be in contact with a poisonous organic solvent in the process of extraction.

Description

technical field [0001] The invention belongs to the extraction and processing method of natural products, and mainly relates to a preparation method of animal fat extract, in particular to a preparation method of ostrich oil. Background technique [0002] Ostriches belong to tropical desert birds and are the largest bird animals. After thousands of years of degeneration, the ostrich has become able to run but not fly, but its explosive power is very strong, reaching 70 kilometers per hour in 3 seconds, and can run continuously for about 40 minutes at a speed of 70 kilometers per hour. Adult ostriches are huge in size and can lift their heads up to 2.5 meters. They have strong endurance, strong regeneration ability, and strong self-healing ability. Surprisingly, ostriches living in cold regions can keep their joints flexible and not rigid at minus 30 degrees. Research by scientists in the United States and Iceland has confirmed that fat cells in bone joints can quickly repa...
