Embodiment 1

[0024] Follow the steps below to extract macadamia nut oil:

[0025] 1. Shell fresh macadamia nuts, crush the nuts to 20 meshes, dry them in an oven at 60°C to constant weight, weigh 1kg and place them in the barrel of a 2L extraction kettle;

[0026] 2. Turn on the refrigeration and cold cycle, and set the temperature of the water tank to 2°C;

[0027] 3. Turn on the heating power, set the extraction temperature to 45°C, the temperature of the separation kettle Ⅰ to 50°C, and the temperature of the separation kettle Ⅱ to 35°C;

[0028] 4. Fully open the cylinder valve, CO 2 Intake valve, CO 2 After the gas passes through the purifier, it enters the cold box for liquefaction. After the temperature reaches the set value, the CO is turned on. 2 pump, CO 2 The gas is pumped into the extraction kettle after passing through the purifier and heater, and the pressure is adjusted to 35MPa to make it into supercritical carbon dioxide. In the extraction kettle, it is fully contacted...

Embodiment 2

[0031] Follow the steps below to extract macadamia nut oil:

[0032] 1. Shell the fresh macadamia nuts, crush the kernels to 40 meshes, dry them in an oven at 60°C to constant weight, weigh 1.5kg and place them in the barrel of a 2L extraction kettle;

[0033] 2. Turn on the refrigeration and cold cycle, and set the temperature of the water tank to 2°C;

[0034] 3. Turn on the heating power, set the extraction temperature to 50°C, the temperature of the separation tank I to 55°C, and the temperature of the separation tank II to 32°C;

[0035] 4. Fully open the cylinder valve, CO 2 Intake valve, CO 2 After the gas passes through the purifier, it enters the cold box for liquefaction.

Abstract

The invention provides a method for extracting macadimia nut oil. According to the method, the macadimia nut oil is extracted from macadimia nuts by a supercritical carbon dioxide extraction method. Test results prove that compared with the prior art, the method has the advantages that the macadimia nut oil is high in extraction efficiency, high in quality and high in content of the unsaturated fatty acid; and a process is simple, convenient to operate, environment-friendly and energy-saving, the extraction time is shortened, and the residues of an organic solvent also can be avoided effectively.

Description

technical field [0001] The invention belongs to the field of vegetable oil extraction, in particular to a method for extracting macadamia nut oil. Background technique [0002] Macadamia integrifolia, also known as macadamia nuts and Australian walnuts, belongs to the genus Macadamia nuts of the family Longanaceae. It is native to Australia. Its edible fruit has the reputation of "Queen of Dried Fruits" and "King of Nuts in the World". Its oil content reaches 78%, of which the proportion of unsaturated fatty acids is more than 80%, mainly oleic acid and palmitoleic acid, and the content of saturated fatty acids is less than 20%. %, mainly palmitic acid. Due to the high content of monounsaturated fatty acids in macadamia oil, long-term consumption of macadamia oil can control blood lipids at a healthy level, effectively reduce blood viscosity, prevent atherosclerosis, and effectively protect the heart and brain Vascular system. The latest research suggests that macadamia n...
