Abstract

The said method extracts fat with fat-soluble organic solvent. Through the processes of removing wax on seed surface, crushing and milk grinding to obtain suspension material, extraction, centrifugal separation of liquid from solid, organic solvent recovery via depressing separated oil, crude oil treatment with active carbon which has been soaked with 5% NaOH solution and 5% sodium citrate solution and water washing, refined gromwell oil is produced with gromwell seeds.

Description

From arnabia seed, extract greasy method

The present invention relates to from arnabia seed, extract greasy method.

Asian puccoon is former to belong to wild plant, does not have under the artificial cultivation condition and can only bloom, solid very few.Having many uses of Asian puccoon, but its root hyoscine has clearing heat and cooling blood, changes the effect of spot detoxifcation, and be the optimum feed stock of extracting natural red colouring matter, contain the unsaturated fatty acids of needed by human body in its seed, have exploitation and be worth.The open CN10922424 of Chinese patent application has disclosed the artificial cultivation method of Asian puccoon, thereby makes large-scale development Asian puccoon and deep processing thereof, becomes possibility.

Be different from general plant, the arnabia seed shell is hard, and the surface is that the cured matter of one deck is surrounded, traditional water for method, milling process, solvent method at all can't high yield obtain internal grease, and traditional method makes the unsaturated fatty acids in the seed be destroyed easily.

The purpose of this invention is to provide and from arnabia seed, extract greasy method

The objective of the invention is to adopt following technical scheme to be achieved: (if no special instructions following, umber by weight) A, remove cured:

Select fat-soluble organic solvent, by 200～400 parts of per 100 parts of seed solubilizing agents, fully stir in 20～40 ℃, the cured matter of flush away seed-coat is filtered, and filtrate is separated cured matter through cooling, and for recycling, control seed moisture percentage is 4～6%.B, pulverizing, defibrination:

To be broken to 80～100 orders except that the seed meal after cured, and add water mill in 40～60 ℃ and starch, the water addition ratio example adds 200～300 parts in water for per 100 parts of seeds (raw material), and defibrination to material is suspended state.C, solvent extraction:

Select and poly-identical organic solvent of A step, in encloses container,, in encloses container, blast nitrogen, displace wherein air, stir 30～45 fens kinds, leave standstill by adding 150～200 parts of organic solvents in the suspension after per 100 parts of seed treatment.D, solid, liquid separate:

Make solid-liquid separation with whizzer, obtaining liquid is left standstill, tell lower floor's water, get the oil phase mixed solution.E, separation solvent

With obtaining oil phase reclaim under reduced pressure organic solvent under 70～80 ℃/50～60mmHg condition, get slightly oil.F, refining

Gac with the mixing solutions dipping that contains 5%NaOH and 5% Trisodium Citrate oven dry after 4 hours, is added 2～3 parts of gacs after handling by per 100 parts of thick oil, fully stirred 30 minutes, filter, oil phase is through being washed to neutrality, treated oil.

Because the present invention has adopted technique scheme, thereby avoided steaming stir-fry process, and made full use of and planted the tannic acid that contains in the shell, and then in last handling process, only use small amount of N aOH and Trisodium Citrate, promptly satisfied refining requirement, simultaneously, technology of the present invention has been avoided in the leaching process destruction to unsaturated fatty acids, and has avoided the follow-up cured process removed.

Treated oil peroxide value after the processing can be low to moderate 1.5meg/kg, fill nitrogen after airtight preservation get final product.

Technology of the present invention is simple, the quality product excellence.

Below in conjunction with embodiment and embodiment in detail the present invention is described in detail.A, remove cured

Select fat-soluble organic solvent, by per 100 parts of seeds, add 200～400 parts of solvents, fully stir in 20-40 ℃, the cured matter of flush away seed-coat is filtered, and filtrate is separated cured matter through cooling, and for recycling, control seed moisture percentage is 4～6%.B, pulverizing, defibrination

To be broken to 80～100 orders except that the seed meal after cured, add water mill slurry in 40～60 ℃, the water addition ratio example be per 100 parts of seeds (raw material) as 200～300 parts in water, defibrination to material is suspended state.C, solvent extraction

Select and poly-identical organic solvent of a step, in encloses container, connect, in encloses container, blast nitrogen, displace wherein air, fully stir 30～45 fens kinds, leave standstill by adding 150～200 parts of organic solvents in the suspension after per 100 parts of seed treatment.D, solid, liquid separate

Make solid-liquid separation with whizzer, obtaining liquid is left standstill, tell lower floor's water, get the oil phase mixed solution.E, separation solution

Obtaining oil phase reduced pressure under 70～80 ℃/50～60mmHg condition four receives organic solvents, oil slightly.F, refining

Gac with the mixing solutions dipping that contains 5%NaOH and 5% Trisodium Citrate oven dry after 4 hours, is added 2～3 parts of gacs after handling by per 100 parts of thick oil, fully stir 30 fens kinds, filter, oil phase is through being washed to neutrality, treated oil.
