Abstract
The invention discloses a grape seed oil extracting method which comprises the following steps: (1), taking grape seeds, soaking for 1-10h by adding clear water, filtering to remove the water, centrifuging for 1-20 min at a speed of 3000r/min, and removing the water; (2) adding the grape seeds in petroleum ether which accounts for 3-6 times of the amount of the grape seeds, performing reflux extraction for 1-6 times with 1-5h every time, and mixing extracting solutions; and (3) recovering the petroleum ether from the extracting solution under a reduced pressure to obtain grape seed oil. According to the grape seed oil extracting method, the grape seed oil is extracted by adopting a solvent, a process is optimized according to the characteristic of the grape seed oil; although the process is simple, the extracted grape seed oil is excellent in quality, and less in impurities.
Description
Technical field
The present invention relates to a kind of grape deep process technology, particularly a kind of raisin seed oil extracting method, belongs to agricultural technology field.
Background technology
Raisin seed oil be Semen Vitis viniferae through modern advanced technologies, extracting the plants essential oil that obtains, be one is almost water white pure natural essential oil product.Raisin seed oil has gentle convergence, can help to tighten and nursing skin, the most important thing is that raisin seed oil is a kind of pure natural components being easy to be absorbed by the skin.It is rich in linolic acid, is a kind of indispensable fatty acid, to skin and cytolemma extremely important.Research shows that raisin seed oil has regeneration and effect of making contributions again, has very strong moisture-keeping function to skin, for the help that Acne treatment is all very large with other dermatosis.
Existing raisin seed oil extracting method mostly is physical squeezing, squeezing process is comparatively ancient, and squeeze the raisin seed oil original cost complexity obtained, impurity is all the organic matter high with Semen Vitis viniferae essential oil phase solubility, later separation difficulty, is thus difficult to the Semen Vitis viniferae essential oil obtaining high-quality.
Summary of the invention
The object of the invention is to overcome the deficiency that squeezing process in prior art prepares the many difficulty separation of raisin seed oil impurity, a kind of raisin seed oil extracting method is provided.
In order to realize foregoing invention object, the invention provides following technical scheme:
A kind of raisin seed oil extracting method, comprises the following steps:
(1) get Semen Vitis viniferae, add clear water and soak 1-10 hour, preferably soak 1-5 hour, elimination moisture, 3000r/min centrifugal treating 1-20 minute, preferred centrifugal 2-5 minute, sloughs moisture content.
(2) Semen Vitis viniferae is joined in the sherwood oil of 3-6 times amount, refluxing extraction 1-6 time, preferred 2-4 time, each 1-5 hour, preferred 1-2 hour, united extraction liquid.
(3) extracting solution reclaim under reduced pressure sherwood oil, obtains raisin seed oil.
Raisin seed oil extracting method of the present invention, adopts clear water to soak and the method that matches of organic solvent extraction, first screens out water-soluble impurity, then solvent extraction, the purity quality of to deduct a percentage point good.Especially clear water soaks the rear centrifuging process coordinated, and good to the pulp removal effect on Semen Vitis viniferae surface, the possibility introducing other impurity component is extremely low, is basically efficient green treatment process.The consumption adding sherwood oil in step 2 is the 2-6 of Semen Vitis viniferae is doubly envelope-bulk to weight ratio (L/KG), and as 10kg Semen Vitis viniferae adds 30L sherwood oil, corresponding ratio is the sherwood oil of 3 times amount.
Further, Semen Vitis viniferae adds in the process of clear water immersion, and by cooperation supersound process, soak time is preferably 1-2 hour.Immersion treatment effectively can remove the water-soluble gum components etc. on Semen Vitis viniferae surface, is conducive to follow-up organic solvent extraction, reduces the unnecessary purifying process of the product that organic solvent extraction obtains.
Further, preferred described sherwood oil to be boiling range the be sherwood oil of 90-120 DEG C.The Petroleum ether extraction poor effect selecting 90-120 DEG C of boiling range is thought in existing research more, if but invention in the present invention coordinates deoxidation treatment in early stage, and then with sherwood oil backflow, extraction effect on the contrary can be better.
Further, this raisin seed oil is added 0.01-0.3wt% unslaked lime, stirs, centrifugal, discard the part containing unslaked lime, obtain pure raisin seed oil.Raisin seed oil creates acidic ingredient by temperature action in leaching process, and the especially easier acidifying of impurity, adds unslaked lime and stir, then centrifugal treating, can obtain colory raisin seed oil.
compared with prior art, beneficial effect of the present invention:
The present invention adopts solvent extraction, and the characteristic according to raisin seed oil carries out process optimization, although technique is simple, extract the raisin seed oil obtained best in quality, impurity is few.
