Abstract
The invention belongs to the technical field of vegetable active ingredient extraction, in particular to a method for extracting linseed oil. In the method, linseeds are used as raw materials, and the linseed oil is obtained by mechanical treatment of raw materials, ultrasonic-assisted solvent extract, solid-liquid separation and liquid-liquid separation. In the invention, ultrasonic is used to assist in solvent extraction of linseed oil, and therefore under a condition that the unsaturated fatty acid content in linseed oil is not changed basically, the extraction yield of linseed oil can be improved greatly, the extraction time can be shortened, the solvent consumption can be reduced and the extraction temperature can be lowered. The process provided by the invention has the characteristics of simple operation, convenient operation, low cost, high speed and high yield compared with the squeezing method, solvent method and supercritical carbon dioxide extraction method.
Description
Technical field
The invention belongs to effective ingredients in plant extraction process technology field, relate to the process for extracting of a vegetable oil, be specially a kind of method of ultrasonic-assisted extraction oleum lini.
Background technology
Linseed oil (flaxseed or linseed) claim flaxseed again, is the seed of the annual of flax family (Linaceae) linum or per nnial herb flax, and flax is one of the world ten big oil crops, in NORTHWEST CHINA, North China and the Northeast extensive plantation is arranged all.
The oil that from linseed oil, obtains is called as oleum lini.Unsaturated fatty acid content reaches more than 80% in the oleum lini, and linolenic acid content is 40%～60%, for the 5-100 of other vegetables oil doubly.Linolenic acid is a kind of omega-3 unsaturated fatty acid, and this kind unsaturated fatty acids can not synthesize in the mankind itself, must from food or nutritious prod, obtain, thereby this type unsaturated fatty acids is called " human indispensable fatty acid (EFA) " again.After linolenic acid was absorbed by the body, the effect through enzyme in small intestine can be converted into docosahexenoic acid (DHA) and two kinds of unsaturated fatty acidss of timnodonic acid (EPA).DHA and EPA have important effect to keeping HUMAN HEALTH with the raising function of human body.Discover and show: often edible oleum lini can effectively prevent and treat illnesss such as mammary cancer, colorectal carcinoma, prostatitis, arteriosclerosis, and can significantly reduce the serum blood fat, suppresses tumor growth.Therefore, oleum lini is effectively extracted have huge economic and social benefit.
Current, the method for extracting oleum lini both at home and abroad is mainly milling process, solvent method and small-scale supercritical carbon dioxide extraction method etc.The milling process productive rate is low, and power consumption is big and the oily impurity of expressed is more.Organic solvent extraction needs very long extraction time usually and needs to consume a large amount of extraction solvents, and the use of a large amount of organic solvents brings adverse influence can for human body and environment.The supercritical carbon dioxide extraction cost is higher, and complex equipments is not easy to operate.Other aqueous enzymatic methods about mentioning among the report of oleum lini process for extracting and patent such as the CN1935962A, this method exists extraction yield lower equally, the problem that extraction time is long.
The method of carrying out the effective ingredients in plant extraction as supplementary means with UW has had the history of two more than ten years, but finds have the people that it is used for carrying out the extraction of oleum lini so far as yet.
Summary of the invention
The objective of the invention is to existing process for extracting extraction time longly, it is low to extract yield, complex equipments, and the cost problem of higher provides a kind of method of utilizing UW ancillary technique extraction oleum lini.
The technical scheme that the ultrasonic-assisted extraction oleum lini method that the present invention proposes is taked comprises the following steps:
1. linseed oil is carried out treat mechanically, treat mechanically comprises and rolling and/or expanded and/or pulverize;
2. getting the linseed meal behind a certain amount of treat mechanically, add the solvent of 4-20 times of weightmeasurement ratio, is that supplementary means is at ultrasound intensity 1-40W/cm with the UW of 20-100kHz
2, extract temperature and be under 20-60 ℃ the situation, ultrasonic-assisted extraction 30-180min;
3. realize separating of solid residue and filtrating through filtering method;
4. place rotatory evaporator in 40-60 ℃ extracting solution, be evaporated to pulpous state under 60-90 rev/min, put into vacuum drier then and further remove solvent, obtain oleum lini.
Treat mechanically be meant carried out rolling, expanded, pulverize or two or three in three kinds of operations, the final state of handling the back material is particle or powdery.Employed extraction solvent is sherwood oil or normal hexane.The ultrasonic-assisted extraction optimum condition is: the mass volume ratio of linseed oil and solvent is 1: 6-10, and ultrasonic frequency is 20-30kHz, ultrasound intensity is 5-15W/cm
2, extracting temperature is 25-40 ℃, extraction time is 60-90min.After obtaining, oleum lini in vacuum drier, carried out further carrying out precipitation treatment again from rotatory evaporator.
Beneficial effect of the present invention:
1, compares with traditional solvent soaking method, under identical extraction yield, shortened extraction time effectively, shortened to present 30-180 minute by original 24-72 hour; And solvent-oil ratio reduces, and is merely the 1/8-1/10 of traditional solvent; Do not need extra-heated in the leaching process, practiced thrift the energy, reduced cost.
2, extraction efficiency is high, has both reduced fat residue in the residue, has practiced thrift oil resource again.
3, can under lower temperature, extract, can avoid the deterioration by oxidation of oleum lini effectively, improve the quality of oleum lini, prolong the period of storage of oleum lini.
4, technology is simple, and is easy to operate, is suitable for suitability for industrialized production, is convenient in the technical transformation of existing solvent method.
