Abstract
A process for preparing the nutritive oil rich in alpha-linolenic acid from the nut of Elsholtria plant includes such steps as pre-treating, softening, extracting coarse oil, refining and purifying. Its advantages include high content of alpha-linolenic acid (90% or more), high stability and low cost.
Description
The invention belongs to the method for producing oil with plant, particularly the method for alpha-linolenic acid nutritional oil is rich in preparation.
Alpha-linolenic acid is the important nutrient of brain, simultaneously diseases such as cardiovascular disorder, hypertension, hyperlipidemia is had good preventing and therapeutic action, but does not contain or contain less alpha-linolenic acid in the at present commercially available oil.In order to obtain this material, American-European countries normally prepares from ocean fish oil, but China's ocean fish natural resources shortage, so can not meet the need of market, and N in the ocean fish oil
-3Unsaturated fatty acids only reaches 3～20%, N
-3/ N
-6Ratio be about 1: 1, away from ideal ratio 3～5: 1, price is also higher in addition.Some are disclosed in patent documentation from such as obtaining the greasy technology that contains alpha-linolenic acid Semen Lini and the perillaseed plant.Semen Lini planting cost height, oleaginousness is low, contains the Toxic that anorexia is used in the oil meal, the inevitable productive expense that further strengthens when removing; Perillaseed oleaginousness height, and be rich in alpha-linolenic acid, but suit growing than the rich soil, planting cost is higher, and the oil-proofness that obtains is relatively poor, and easy oxidation enzymolysis is if will address this problem, need to adopt complicated technology means such as thermofixation described in patent documentation, weak base saponification, so cost is also higher.
The purpose of this invention is to provide and a kind ofly belong to the method that the alpha-linolenic acid nutritional oil is rich in the nut preparation by elscholtiza, the aboundresources of its raw material, easily plantation, it is many to contain alpha-linolenic acid, and production technique is simple, and product stability is good, and cost is low.
Implementation of the present invention is: adopting the nut of Labiatae (Labiatae) elscholtiza (Elsholtria) platymiscium is raw material, produce nutritional oil through following operation: i.e. elscholtiza nut → give processing → softening → extract crude oil → refining to get essential oil, in the resulting oil of preparation, alpha-linolenic acid accounts for 55～63% of total fatty acid content, iodine number is 170～190Ig/100g, N
-3Alpha-linolenic acid/N
-6The ratio of linolic acid is 2.2～3.5.
When extracting crude oil, can adopt traditional mechanical expression technology, also can adopt the solvent extracting technology, the oil-collecting ratio of squeezing process is 85～90%, and the solvent extraction method oil-collecting ratio is 90～98%.Solvent extraction method employing boiling point is 30～120 ℃ alkanes or ether solvent lixiviate, as using any one or two kinds of above mixing the in ether, sherwood oil, petroleum naphtha, No. 6 solvents, normal hexane, trichloroethane, the trieline, by the weight of material ratio of elscholtiza nut and solvent is 1: 4～8 to add solvents, extract under refluxing, the time is 4～12 hours.
Earlier alkali lye will be added in the crude oil when carrying essential oil, stir, precipitation, the processing of coming unstuck is warmed up to 85～90 ℃ again and washes, 80～120 ℃ of following processed, adding discoloring agent down at 90～105 ℃ again stirs, be heated to 120～140 ℃ at last, under vacuum tightness residual voltage 0.50～0.55KPa, keep carrying out in 2～3 hours deodorization and handle, make essential oil.
Below, several specific embodiment of the present invention is provided, its technology is further described.
Embodiment 1
Get exsiccant Root of Shrubby Elsholtzia [Elsholtria Fruticosa (D Don) Rehd.] nut 20 grams, broken or roll into base, put into filter paper, bandage and put into extractor, add 120 gram sherwood oils immersions and part is flowed in the flask, reflux, return velocity is that the time is 10 hours per hour 8～9 times.Take out filter paper packet, heating is reclaimed sherwood oil with solvent evaporation, eliminate behind the solvent crude oil 8.5 grams, yield is 42%, yield is 98% (macadamia nut oil content is 43%), alpha-linolenic acid accounts for 61.52% of total fatty acid content, iodine number is 188.5Ig/100g, N
-3Alpha-linolenic acid/N
-6The ratio of linolic acid is 2.89.
Get the above-mentioned nut crude oil that makes of 100 grams, the sodium hydroxide solution that in the beaker of 250ml, adds calculated amount under the whipped state, concentration is 11.11%, 45 ℃ of temperature, continue insulation 30～60 minutes, when treating the separated attitude of oil and neat soap, be heated to 60～70 ℃ and continue to stir 10 minutes, staticly settle, emit throw out (processing of promptly coming unstuck).Temperature is raised to 85～90 ℃ again, each water of about 10% that accounts for weight of oil that adds under agitation carries out 2～3 washings, and separation is anhydrated, reheat to 80～120 ℃ dehydration down.The acid atlapulgite of adding 3% stirred 50 minutes as discoloring agent under 90～105 ℃, stopped to stir the elimination carclazyte.Reheat to 120～140 ℃ keep deodorization in 2～3 hours in the container of vacuum tightness residual voltage 0.50～0.55KPa, can obtain essential oil 95 grams, and yield is 95%, and alpha-linolenic acid accounts for 63% of total fatty acid content.
Embodiment 2
Get exsiccant vanillon [Elsholtria Cypriani (pavol.) C.Y.Wu et S.chow] nut 50 grams, broken or roll into base, put into the there-necked flask of band condenser, add for the first time normal hexane 180 grams, at room temperature stirred 3 hours, standing demix, heating and separating goes out normal hexane, add for the second time normal hexane 120 grams again, repeat again by above step.The filter and remove residue dregs of rice, the heating evaporation solvent reclaims normal hexane, eliminate behind the solvent crude oil 18.5 grams, yield is 37%, yield is 97% (macadamia nut oil content is 38%), alpha-linolenic acid accounts for 60.10% of total fatty acid content, iodine number is 182.5Ig/100g, N
