Abstract
The invention provides a supercritical extraction technology for East China wild walnut oil. According to the method, the East China wild walnut oil is obtained through a CO2 supercritical extraction step and a hyperfiltration step. During the production process, particularly the refining process of the East China wild walnut oil, no chemical reagent is added, a pure physical method is adopted for refining, and the obtained East China wild walnut oil keeps special active substance, such as juglans mandshurica, vitamin E and the like, of East China wild walnuts, does not have residual solvent, and is pollution-free, good in safety and high in oil product quality. As no chemical reagents are added during the refining process, and no chemical residual reagents are added, the East China wild walnut oil can serve as high-end edible oil and cosmetic or a pharmaceutical additive. By eating the East China wild walnut oil or using the East China wild walnut oil in drugs, the East China wild walnut oil can have the effect of tonifying the kidney, benefiting the lung, improving inspiration, relieving asthma, and relaxing bowel. The East China wild walnut oil is fragrant in smell and unique in taste, can be widely applied to the cooking of various food and dishes, has high nutritive value and health care effect, guarantees high-antioxidant active constituents, and is particularly applied to the promotion in the field of a small-lot special oil production technology.
Description
Technical field
The present invention relates to the method for a kind of East China Chinese walnut oil supercritical extraction, art: two, biological and new medical technology, (7) modern agricultural technology, 4, agricultural-food intensive processing and modern accumulating: agriculture and forestry product and extraordinary enhance productivity are processed.
Background technology
East China Chinese walnut, deciduous tree, originates in area, the Near East, also known as English walnut, Qiang peach, with almond, cashew nut, fibert being called world-renowned " four large dry fruits ".Both can eat raw, stir-fry and eat, and also can extract oil, prepare cake, candy etc., not only delicious, and also nutritive value is very high, is described as " long live ", " Longevity ".Walnut after squeezing contains a large amount of unsaturated fatty acids, part linolic acid, is rich in the nutritive substances such as natural VA, VD simultaneously, the metabolic impurity of Ink vessel transfusing can be got rid of, make blood purification, for brain provides fresh blood, though the nutritive element of walnut oil is high, but the squeezing mode existed now can destroy multi-nutrition beneficiating ingredient in walnut, greatly reduces the healthy nutritive value of walnut oil.
Summary of the invention
The object of the present invention is to provide the East China Chinese walnut oil producing method of a kind of easy, nutritive value and health care, rational technology.
Technical scheme of the present invention is achieved in that and comprises the steps:
A, airing is carried out to East China Chinese walnut, control water ratio 3%-5%;
B, the East China Semen juglandis cathayensis dried put into freezing 3 ~ 9 hours of the refrigerated tank of-25 DEG C, to be placed in the vacuum environment of-10 DEG C 3 ~ 8 hours, be finally placed in 40 ~ 60 DEG C of vacuum environment drying treatment 2 ~ 7 hours;
C, the East China Semen juglandis cathayensis pulverizing will obtained after B, process, sieve by 20 ~ 40 mesh sieve;
D, CO
2supercritical extraction, fluid extraction pressure is 35 ~ 45MPa, extraction temperature 35 ~ 45 DEG C, CO
2fluid flow rate is 800 ~ 1100L/h, and extraction time is 40 ~ 100 minutes, obtains East China Semen juglandis cathayensis slightly oily;
E, hyperfiltration remove lipoxygenase, select the hyperfiltration film of molecular weight cut-off 80-120kD, carry out hyperfiltration process to the East China Chinese walnut oil after filtering;
F, uv irradiating, the East China Chinese walnut oil flow after filtration settles the irradiating unit of ultraviolet lamp by top, and irradiation dose is 300-400J/m2, and irradiation time is 10-20 second.
Compared with prior art the inventive method tool has the following advantages: (1) the invention provides a kind of East China Chinese walnut oil production technique, particularly in the refining process of East China Chinese walnut oil, do not add chemical reagent, pure physical method is adopted to carry out refining, the East China Chinese walnut oil obtained remains the distinctive Juglans mandshurica of East China Chinese walnut and vitamin-E isoreactivity material, and no solvent residue, pollution-free, security good, oil quality is high.Owing to not adding any chemical reagent in extractive process, without chemical residual reagent, can be used as fabulous high-end edible oil and makeup or pharmacy additive.Edible and in medicine can kidney tonifying benefit lung, helping inspiration to relieve asthma, relax bowel; (2) the present invention utilizes Lyophilisation technique for making, is convenient to by walnut kernel pulverize; (3) the present invention utilizes CO
2supercritical extraction technique, make do not have organic solvent residual in product, the crude oil color and luster that simultaneously extracts is more shallow than squeezing East China Chinese walnut oil, do not need through coming unstuck, alkali refining, decolouring, deodorization process, thus the loss such as natural nutrition VE is few, and also not producing the objectionable impuritiess such as trans fatty acid provides; (4) the present invention utilizes ultra micro membrane filtration technique, eliminates in the Chinese walnut oil storage process of East China and causes rotten biotic factor; Oxygenase in the Chinese walnut oil of East China, in storage process, the double bond fracture in the unsaturated fatty acids in the Chinese walnut oil of catalyzed oxidation East China, produces the smell substances such as aldehyde ketone and produces, make East China Chinese walnut oil deterioration; Tradition hot moulding utilizes high temperature to make oxygenase deactivation; Solvent extraction method is in refining process, make oxygenase inactivation; Technique of the present invention is without heat denatured process, also do not carry out refining, and adopt ultra micro membrane filtration technique, the lipoxygenase in the Chinese walnut of ultrafiltration removing East China, eliminate in the Chinese walnut oil storage process of East China and cause rotten biotic factor, and the clarity simultaneously added; (5) the present invention utilizes uv irradiating technology, kills the activity of fatty oxygenase do not removed completely in hyperfiltration process, and destroys the structure of remaining aflatoxin further, reaches the object eliminated further.In order to ensure the circulation of ultrafiltration, the ultra-filtration membrane of the 80-120KD selected in technique, can remove most lipoxygenase, but can not remove completely.Remaining lipoxygenase, utilizes the uv irradiating process of low dosage, both can ensure that the quality of oil is not suffered a loss, can reduce again residual fat oxygenase further active, ensure the storage of oil.Meanwhile, utilize the wavelength of UV-light short, energy is large, when being irradiated to body surface, is easily subsequently absorbed in the material, becomes the interior energy of material, destroys the characteristic of the chemical bond of material molecule, reduces the aflatoxin content in the Chinese walnut oil of East China further; The aldehyde material letones of rapid removal wherein in peculiar smell, and produce the free fatty acids of peculiar smell, and ensure that nutritive substance loss is wherein little; (6) in the high-quality grease that the present invention produces, because be rich in the natural antioxidantss such as natural VE, do not need in grease storage process additionally to add oxidation inhibitor.
The invention provides the East China Chinese walnut oil producing method of a kind of easy, nutritive value and health care, rational technology, can produce for short run special oil and technical support is provided, be suitable for promoting in edible fat production technical field.
