Embodiment 1

[0015] (1) Wash and dry 1kg of papaya seeds, pulverize them to 40 mesh and place them in the barrel of a 1L extraction kettle;

[0016] (2) Turn on the refrigeration and cold cycle, set the temperature of the cold box to 0°C; set the temperature of the extraction kettle to 50°C, the temperature of the separation kettle I to 45°C, and the temperature of the separation kettle II to 55°C, and then turn on the CO 2 Cylinder, CO 2 Enter the cold box for liquefaction through the gas purifier I, and then start the high-pressure pump to convert the CO 2 It is pumped into the extraction kettle through the purifier II and the heater, and the pressure is increased to 25MPa to make it a supercritical fluid. In the extraction kettle, it is fully mixed with papaya seeds, so that the papaya seed oil dissolves to CO 2 Medium; (3) CO dissolved in papaya seed oil 2 It flows out from the top of the extraction kettle and enters the depressurization system. In order to realize the complete separ...

Embodiment 2

[0018] (1) Wash and dry 1kg of papaya seeds, pulverize them to 30 mesh and place them in the barrel of a 1L extraction kettle;

[0019] (2) Turn on the refrigeration and cold cycle, set the temperature of the cold box to 0°C; set the temperature of the extraction kettle to 40°C, set the temperature of the separation kettle I to 50°C, and set the temperature of the separation kettle II to 50°C, then turn on the CO 2 Cylinder, CO 2 Enter the cold box for liquefaction through the gas purifier I, and then start the high-pressure pump to convert the CO 2 It is pumped into the extraction kettle through the purifier II and the heater, and the pressure is increased to 20MPa to make it a supercritical fluid. In the extraction kettle, it is fully mixed with papaya seeds to make the papaya seed oil dissolve to CO 2 Medium; (3) CO dissolved in papaya seed oil 2 It flows out from the top of the extraction kettle and enters the depressurization system.

Embodiment 3

[0021] (1) Wash and dry 1kg of papaya seeds, crush them to 50 mesh and place them in the barrel of a 1L extraction kettle;

[0022] (2) Turn on the refrigeration and cold cycle, set the temperature of the cold box to 0°C; set the temperature of the extraction kettle to 45°C, the temperature of the separation kettle I to 40°C, and the temperature of the separation kettle II to 40°C, and then turn on the CO 2 Cylinder, CO 2 Enter the cold box for liquefaction through the gas purifier I, and then start the high-pressure pump to convert the CO 2 It is pumped into the extraction kettle through the purifier II and the heater, and the pressure is increased to 35MPa to make it a supercritical fluid. In the extraction kettle, it is fully mixed with the papaya seeds to dissolve the papaya seed oil to CO 2 Medium; (3) CO dissolved in papaya seed oil 2 It flows out from the top of the extraction kettle and enters the depressurization system.

Abstract

The invention claims a method for extracting papaya seed oil by using supercritical CO2, comprising the following steps of: drying and crushing the papaya seed, filling the dried and crushed papaya seed in a barrel, sealing the barrel, introducing CO2, heating up and pressurizing the barrel to enable CO2 to be the supercritical fluid, mixing the supercritical fluid with the papaya seed in an extraction kettle and extracting the mixture; and then decompressing the mixture, and separating the papaya seed oil from CO2 to obtain the papaya seed oil. The invention has the advantages of simple technical process, high extraction efficiency, high quality of product, no remaining solvent and no pollution to the environment.

Description

technical field [0001] The invention relates to the fields of food and bioengineering, in particular to a supercritical CO 2 Extraction of papaya seed oil and method. Background technique [0002] The oil content of papaya seeds is about 30%, and its composition is mainly monounsaturated fatty acid-oleic acid, and its content is as high as more than 70%. Oleic acid can maintain the balanced concentration of "high-density lipoprotein cholesterol" to ensure the body's demand for cholesterol; oleic acid can prevent atherosclerosis, regulate blood lipids, lower blood pressure, reduce blood viscosity, prevent the formation of thrombus, and protect the heart Avoid the harm of coronary heart disease and reduce the occurrence of cardiovascular diseases; oleic acid can also moderately control blood sugar levels, improve lipid metabolism, and have a certain therapeutic effect on diabetes. Therefore, papaya seed oil is a high-quality natural vegetable oil with great development value...
