Abstract
The invention discloses a kind of supercritical extraction method of walnut oil, this method is that walnut oil is extracted from walnut kernel using supercritical carbon dioxide fluid, i.e., first that walnut is dry；Again by the crushing of the walnut after drying；Then being extracted from smashed walnut kernel using supercritical carbon dioxide fluid can be prepared by walnut oil finished product；The present invention is to use CO2 as extractant in the supercritical state, and solvent consumption is few, and obtains the high income of product, to reduce the extraction cost of walnut oil.CO 2 fluid is green non-pollution solvent, and the walnut oil of extraction has the features such as high-quality, purity is high, color is good, free from extraneous odour, no solvent residue, non-environmental-pollution, and extraction cycle is short.Present invention process is simple, and low energy consumption.
Description
Technical field
The present invention relates to a kind of supercritical extraction methods of walnut oil, belong to technical field of natural product extraction.
Background technique
The extracting method of walnut oil mainly has at present: supercritical CO2Extraction；Extraction mentions oil process；Water substitution；Water phase
Enzyme process；Squeezing method etc..Current walnut oil extracting method main problem includes: that walnut oil quality is low, environmental pollution is big, is extracted into
The disadvantages of this is higher.
Summary of the invention
The purpose of the present invention is to provide a kind of supercritical extraction method of walnut oil, to improve walnut oil yield and oil
Quality reduces environmental pollution, extraction cost is reduced, thus overcome the deficiencies in the prior art.
The technical scheme of the present invention is realized as follows:
A kind of supercritical extraction method of walnut oil of the invention, method includes the following steps:
1) drying of walnut；
2) crushing of the walnut after drying；
3) walnut oil is extracted from smashed walnut kernel using supercritical carbon dioxide fluid.
In preceding method, walnut powder after drying is put into the material barrel of extraction kettle by when extraction, by titanium dioxide
Carbon gas injects extraction kettle, keeps the temperature and pressure in extraction kettle in the supercriticality and natural material of carbon dioxide gas
Contact, is dissolved in the walnut oil component in walnut powder among supercritical fluid, and from the outlet of separating still, collection contains walnut oil
Fluid.
In preceding method, the supercriticality temperature is 35 DEG C~45 DEG C, and extracting pressure is 35MPa~45MPa；Dioxy
Changing carbon gas by the flow of extraction kettle is 150~250kg/h, and extraction time is 1.2h~2.5h, separation temperature when extraction
It is 30 DEG C~45 DEG C, separating pressure 14MPa.
In preceding method, the drying is that the walnut that will be cleaned is put into baking oven, is dried at a temperature of 50~60 DEG C to walnut
To water content in 10~15% ranges, then puts it into pulverizer and be ground into the walnut powder that partial size is greater than 60 mesh.
By adopting the above-described technical solution, compared with prior art, the present invention the present invention is to make in the supercritical state
Use CO2 as extractant, solvent consumption greatly reduces, and obtains the high income of product, to significantly reduce walnut oil
Extraction cost.CO 2 fluid used in the present invention is green non-pollution solvent, and the walnut oil of extraction has high-quality, purity
The features such as height, color is good, free from extraneous odour, no solvent residue, non-environmental-pollution, and extraction cycle is short.Therefore, the present invention not only has
Can effectively improve walnut oil yield and oil quality the advantages of, but also have can effectively reduce environmental pollution, production technology letter
List, low energy consumption, small investment, the advantages that extraction cost can be effectively reduced.
Specific embodiment
Below with reference to embodiment, the present invention is further illustrated:
The embodiment of the present invention: when using a kind of supercritical extraction method of walnut oil of the invention, existing skill can be directlyed adopt
Drying equipment, disintegrating apparatus and extraction kettle in art are produced, and the method for the present invention includes the following steps:
1) drying of walnut；
2) crushing of the walnut after drying；
3) being extracted from smashed walnut kernel using supercritical carbon dioxide fluid can be prepared by walnut oil finished product；It will when extraction
Walnut powder after drying is put into the material barrel of extraction kettle, and carbon dioxide gas is injected extraction kettle, is kept in extraction kettle
Temperature and pressure is contacted in the supercriticality of carbon dioxide gas with natural material, dissolves the walnut oil component in walnut powder
Among supercritical fluid, the fluid containing walnut oil is collected from the outlet of separating still；The temperature of its supercriticality is preferably controlled
System is at 35 DEG C~45 DEG C, and for extracting pressure general control in the range of 35MPa~45MPa, extracting pressure is preferably 40MPa；Dioxy
Changing the flow that carbon gas passes through extraction kettle is 150~250kg/h, and extraction time controls the range in 1.2h~2.5h, general feelings
Extraction time is 1.5h under condition, and separation temperature when extraction is 30 DEG C~45 DEG C, separating pressure 14MPa；Its drying is will to clean
Walnut be put into baking oven, water content is dried within the scope of 10-15% to walnut at a temperature of 50~60 DEG C, is then put it into
Pulverizer is ground into the walnut powder that partial size is greater than 60 mesh.
Referring to the measuring method of fat and fat oil in first annex IX N of Pharmacopoeia of the People's Republic of China version in 2010
And IX P degree of rancidity measuring method carries out quality evaluation, present invention walnut oil institute produced to present invention walnut oil produced
Acid value, peroxide value and iodine number for containing etc. not only conform with Pharmacopoeia of the People's Republic of China set quota, and use this hair
Bright walnut oil quality produced is significantly better than the quality using existing traditional technology walnut oil produced.
