Abstract
The invention provides a supercritical extraction process for Rubus Chingii Hu oil. The Rubus Chingii Hu oil is obtained through the steps of CO2 supercritical extraction and hyperfiltration. In the production process, particularly in the refining process of the Rubus Chingii Hu oil, a chemical reagent is not added, a purely physical method is adopted for refining, the obtained Rubus Chingii Hu oil reserves special rutin, tiliroside, quercetin and other flavonoids as well as vitamin E and other active materials of the Rubus Chingii Hu, and is free of solvent residues and pollution, good in safety and high in quality. Since no chemical reagent is added in the refining process, and no chemical reagent residue is realized, the Rubus Chingii Hu oil can be used as high-end edible oil and high-end cosmetic or a pharmaceutical additive. The Rubus Chingii Hu oil is fragrant in smell and unique in flavor, can be widely used for cooking various foods and dishes, has a relatively high nutritive value and a healthcare health-preserving effect, ensures high-antioxidant active ingredients and is particularly suitable for being popularized in the technical field of small-batch special oil production.
Description
Technical field
The present invention relates to the method for a kind of rubus chingii Hu oil supercritical extraction, art: biological and new medical technology, modern agricultural technology, agricultural-food intensive processing and modern accumulating: agriculture and forestry product and extraordinary enhance productivity are processed.
Background technology
Rubus chingii Hu, i.e. Rosaceae rubus (RubusLinn) plant raspberry (English name: Raspberry, Latin title: RubusChingiiHu, Chinese: raspberry, raspberry, another name: cover basin, Rubus corchorifolius, little pallet, the bubble that tills the land, father-in-law turns round, milk is female) seed.Raspberry is referred to as " ruby " America and Europe, is third generation gold fruit.Raspberry seed oil is rare plant oil, is table oil and cosmetic material.
Raspberry seed is the by product after wine brewing or juice production, generally accounts for fruit heavy by 10%.Oleaginousness 8-15% in raspberry seed, the extraction of raspberry seed oil can adopt milling process, supercritical extraction and extraction etc.It is good that traditional milling process has oil quality, lighter color, the advantages such as pure flavor, but the resid amount squeezed in rear cake slag is high, and oil yield is low, and energy consumption is large; Supercritical extraction oil yield is high, and oil is also better, but cost is too high and be not suitable for scale operation; Extraction oil yield is high, impure more in the crude oil of leaching, and color and luster is comparatively dark, and oil yield is high, easily realizes scale operation.
Summary of the invention
The object of the present invention is to provide the rubus chingii Hu 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 rubus chingii Hu, control water ratio 3%-5%;
B, the rubus chingii Hu benevolence of drying 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 rubus chingii Hu benevolence 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 rubus chingii Hu benevolence slightly oily;
E, hyperfiltration remove lipoxygenase, select the hyperfiltration film of molecular weight cut-off 80-120kD, carry out hyperfiltration process to the rubus chingii Hu oil after filtering;
F, uv irradiating, the rubus chingii Hu 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 rubus chingii Hu oil production technique, particularly in the refining process of rubus chingii Hu oil, do not add chemical reagent, pure physical method is adopted to carry out refining, the rubus chingii Hu oil obtained remains Flavonoid substances and the vitamin-E isoreactivity materials such as the distinctive rutin of rubus chingii Hu, tiliroside, Quercetin, 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 rubus chingii Hu 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 rubus chingii Hu oil storage process and causes rotten biotic factor; Oxygenase in rubus chingii Hu oil, in storage process, the double bond fracture in the unsaturated fatty acids in catalyzed oxidation rubus chingii Hu oil, produces the smell substances such as aldehyde ketone and produces, make rubus chingii Hu 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 ultrafiltration removing rubus chingii Hu, eliminate in rubus chingii Hu oil storage process 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 rubus chingii Hu oil 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 rubus chingii Hu 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.
