Abstract
The invention relates to an ultrasonic extracting method for a natural active ingredient of highland barley plumule oil in highland barley. In the method, grinded highland barley plumule powder is used as raw material; certain proportion organic solvent is added for soaking at room temperature. The mixed highland barley plumule powder and organic solvent are put into an ultrasonic extracting kettle for extracting. The extracting liquid after ultrasonic extraction is centrifugated or filtered, then clear liquid is obtained. The clear liquid is carried out vacuum concentration or film concentration for obtaining solvent, thus the highland barley plumule oil with 9.1-11.7 percent of yield is obtained. Compared with the existing extracting methods, the biological activity of the extract is good and the yield is increased by 2-5 percent, as well as the extracting time is shortened and energy consumption of extracting material is reduced. The ultrasonic extracting method has the advantages of simple technical process, easy control operation and good safety of equipment, as well as being suitable for industrial production. Furthermore, the ultrasonic extracting method greatly promotes the comprehensive utilization economic value of the highland barley.
Description
Technical field the present invention relates to the method for the separation and Extraction of active component in the natural products.Particularly use the method for ultrasonic extraction highland barley embryo bud oil.
Background technology highland barley (Hordeum Vulgare L.var nudum Hook.f) belongs to one of grass family wheat family Hordeum barley mutation on plant classification.Highland barley is Qinghai-Tibet topmost cereal crops, but because process technology falls behind, the product mouthfeel is relatively poor, though in the problem of food and clothing that solves local peasants and herdsmen, played important function, the deep processing and the comprehensive utilization of development highland barley characteristic agricultural product, improve its added value, extremely more urgent.Highland barley flour contains the dietary fiber that a large amount of β one glucan etc. has plurality of health care functions, can develop the auxiliary material as Flour product.Barley germ contains the abundant unrighted acid except the same with wheat embryo, also contains abundant VE, VD.Therefore the embryo oil with barley germ production has better health-care effect.
At present, produce highland barley embryo bud oil in the prior art and mainly contain three kinds of methods: 1. supercritical carbon dioxide extraction method, pairing product quality is more excellent, recovery rate higher (6-9%).But its technological requirement high pressure and low temperature, the extraction time is about 5 hours, the equipment investment costliness, thereby equipment cost and running cost are all higher; 2. conventional solvent extraction method, its extraction time is grown (1-16h), and the crude oil of proposition also needs to handle, thereby technology is complicated, and corresponding quality and productive rate are not high yet; 3. the milling process technology is less demanding, also is easy to large-scale production.But productive rate is not high, generally has only 5%, makes that in the squeezing of higher temperature (85 ℃-95 ℃) situation the active component in the wheat-germ oil is destroyed; Press the method that is equipped with a blue or green embryo oil though having occurred colds pressing, promptly adopt the press for extracting juice mode of colding pressing to produce embryo oil, kept the effective active composition in the blue or green embryo oil effectively; But productive rate is still not high, and preparation method loaded down with trivial details (referring to Chinese patent CN1875733, the method for preparing highland barley embryo bud oil by cold pressing).
The invention content purpose of the present invention provide in order to overcome above-mentioned the deficiencies in the prior art part just a kind of simple, recovery rate is high, the preparation method of the ultrasonic extraction of lower-cost highland barley embryo bud oil.
Ultrasonic wave is a kind of elastic mechanical vibration wave, and the extraction that it is applied to Pharmaceutical Analysis and chemical composition as a kind of extractive technique has had the research history of two more than ten years.Ultrasound assisted extraction technique is to utilize multiple primary and secondary level effects such as ultrasonic cavitation effect, mechanical oscillation, fuel factor, in fluid, produce the HTHP field of moment, the surface of solids in the convection cell produces powerful shearing force, quicken the stripping of active skull cap components and strengthen mass transport process, so also claim ultrasound-enhanced extraction.Utilize the multiple-effect of ultrasonication, lower temperature and short extraction time, avoided the stripping of other impurity in the barley germ, obtain comparatively pure oil product, also preserved active component wherein simultaneously effectively.
Technical scheme of the present invention is achieved in that the barley germ powder to pulverize is a raw material, powder particle diameter is 20-150 μ m, adding organic solvent at room temperature soaked 0.5-12 hour, wherein, weight/the Capacity Ratio of barley germ powder and organic solvent is 1: 2-20, the barley germ powder and the organic solvent that mix are in proportion placed ultrasonic extraction still, at supersonic frequency 20-800KHz, ultrasound intensity 0.3-15W/cm
2, extract under the condition of 10-80 ℃ of temperature, extracted 0.2-6 hour, through centrifugal or suction filtration, get supernatant liquid through the extract after the ultrasonic extraction, reducing pressure concentrates or the concentrated solvent that reclaims of film, obtains the highland barley embryo bud oil that yield is 9.1-11.7%.
Organic solvent is selected: benzinum, chloroform, ethanol, acetone or ether.
The present invention compared with prior art has following advantage:
1. because hyperacoustic multiple-effect during ultrasonic extraction, as cavitation, stirring, the diffusion of reinforcement mass transfer etc., the motion of accelerated solvent, impel solvent in cell, to permeate, helping embryo oil shifts to solvent from the barley germ powder, and and solvent fully mix, promote the extraction of active ingredient, the extraction efficiency height.
2. compare with the solvent extraction method of routine, yield improves 2-5%, and has shortened extraction time, has reduced the energy consumption of unit material, and the solvent consumption is less relatively, and the product yield height is usually at 9.1-11.7%.
3. and supercritical CO
2Extraction method is compared, and does not need high-tension apparatus, and the disposable input expense of equipment is low.
4. technological process is simple, and convenient being difficult for of slagging tap stops up, and production operation is controlled easily, and the security of equipment is good, is fit to industrial production.
5. ultrasound assisted extraction technique is a kind of low-temperature physics leaching process, so the biologically active of extract is intact.
