According to the method for extracting the grape seed oil through wetting-method squeezing, the grape seeds are wetted with salt water to make organization structures of grape seed shells change greatly, enzymolysis is performed to destroy and smash the shell structures of the grape seeds, then low-temperature pressing is performed, ingredients of the grape seeds can be retained to the most degree through low-temperature pressing, effective health-care ingredients are not destroyed, and the grape seed oil yield is greatly improved through the enzymolysis.
Description
Technical field
The present invention relates to Oleum Vitis viniferae extracting method is and in particular to dampening squeezes the method extracting Oleum Vitis viniferae.
Background technology
Semen Vitis viniferae contains extremely abundant Oleum Vitis viniferae, about the 14%～17% of Semen Vitis viniferae dry weight.Contain in Oleum Vitis viniferae
There are Palmic acid, Oleic acid, linoleic acid and micro linolenic acid, lauric acid, myristic acid etc., unsaturated fatty acid content is up to 90%
More than, linoleic acid content reaches 65%～85%, is a kind of edible oil of great good health care.
China's industrialized production Oleum Vitis viniferae main method is decoction and alcohol sedimentation technique, solvent extraction method, conventional press method at present.
Using decoction and alcohol sedimentation technique, Semen Vitis viniferae loss of effective components is more, and extraction ratio is low, and cost is also higher.The Portugal that solvent extraction method extracts
There is a certain degree of dissolvent residual in grape seed oil, this brings certain hidden danger for food safety；And conventional press method is in high temperature
Under the conditions of extract Oleum Vitis viniferae, it is especially biological that too high pressing temperature destroys contained effective nutritional labeling in Oleum Vitis viniferae
Active component.
Content of the invention
For above-mentioned technical problem, the present invention provides a kind of Oleum Vitis viniferae new method for squeezing and extracting, reaches production cost
Low, oil yield is high, and fuel-displaced quality better, will not destroy effective nutrition abundant.
Specifically technical scheme is：
The method that Oleum Vitis viniferae is extracted in dampening squeezing, including procedure below：
(1) Semen Vitis viniferae is dried naturally, add saline solution stirring moistening；Saline is the salt solution of concentration 5～10g/L.
Preferably, the change further with temperature step by step to carry out moistening, and specific preferred version is：Under 20-25 degree Celsius, add
The saline solution stirring 5-10 minute of 5g/L, then proceedes to add Sal so that concentration reaches 8g/L, is warmed to 35-40 Celsius simultaneously
Degree keeps 5-10 minute, then proceedes to add Sal so that concentration reaches 10g/L, is warmed to 45-50 degree Celsius of holding 5- simultaneously
10 minutes, nature airing temperature is down to that room temperature is stand-by after Semen Vitis viniferae is pulled out, the change of this temperature step by step is carrying out moistening
Effect very good, 0.2% about can be improved on the oil yield of final products, be an important invention of the present invention
Point, by Sal water-wet Semen Vitis viniferae, makes the organizational structure of Semen Vitis viniferae shell change, then when enzymolysis, very
Easily Semen Vitis viniferae shell mechanism is destroyed, drastically increased oil yield.
(2) after Semen Vitis viniferae clean water, add cellulase, addition is 5～100,000 unit of activity/0.1g Fructus Vitis viniferae
Seed, insulation carries out being digested.Cellulase comprises endoglucanase, 1,4-BETA-D-glucancellobio-hydrolase, beta-glucosidase etc..
(3), after Semen Vitis viniferae sterilizing, drying to water content is 4～8%；
(4) Semen Vitis viniferae of drying is pulverized, the grape pip powder obtaining that particle diameter is 0.5～5mm of sieving；It is at present in the industry
Cost-effective, generally using by the method for direct for material to be extracted oil cold pressing, but inventor has surprisingly found that, increases precomminution
After step, oil yield can be made to improve, this is an important inventive point of the present invention, but due to the Semen Vitis viniferae after crushing
Can be kneaded into bulk, affect oil yield, so increased to be passed through steam in grape pip powder and carry out the mode of adjusting water content content preventing
It is kneaded into bulk impact oil yield；
(5) be passed through in grape pip powder steam carry out quenched, to grape pip powder water content be 10～15%；
(6) grape pip powder after will be quenched loads cold pressing expeller, and cold pressing Stress control is in 12～30MPa, cold pressing temperature range
Control in room temperature～60 DEG C, obtain expressed oil and cake slag；
(7) expressed oil carries out primary filter, in 5～10 DEG C of environment, then carries out fine filtering, the standard of fine filtering is
Impurity content ＜ 0.1 in expressed oil；By expressed oil under vacuum -0.05～0.08MPa, add 0.3～0.5% activated carbon, will
Expressed oil is heated to 55～60 DEG C, stirs 30min, be subsequently cooled to room temperature under rotating speed 55～70r/min, filters, except deactivation
Property charcoal, standing obtain within 72 hours finished press oil.
Inventor, through test of many times, has obtained an important inventive point of the present invention, that is, in order to fully extract
Oil in Semen Vitis viniferae, also includes following expressing process：
(8) the cake ground-slag obtaining cold press is broken, adds hemicellulase, and addition is 5～100,000 unit of activity/0.1g
Cake slag；
(9) the cake slag after digesting is heated to 110～120 DEG C, squeezes out Residual oil again；
(10) Residual oil is carried out primary filter, then multiple fine filtering again in the environment of room temperature, make to contain in Residual oil miscellaneous
Amount ＜ 0.1；By Residual oil under vacuum -0.05～0.08MPa, add 0.3～0.5% activated carbon, Residual oil is heated to 100～
115 DEG C, stir 30min under rotating speed 55～70r/min, be subsequently cooled to 70～80 DEG C, filter, remove activated carbon, stand 72
Hour obtains hot pressed oil.
The method that Oleum Vitis viniferae is extracted in the dampening squeezing that the present invention provides, by salt water-wet Semen Vitis viniferae, makes Semen Vitis viniferae
The organizational structure of shell changes, then is digested, and Semen Vitis viniferae shell mechanism is destroyed, and after pulverizing, first carries out low temperature
Squeezing, low temperature pressing can be maximally maintained the composition of Semen Vitis viniferae, and effective health-care components will not be destroyed, and digests
Greatly improve the oil yield of Semen Vitis viniferae, the cake slag after squeezing is further carried out digesting, after enzymolysis processing, Semen Vitis viniferae cell
Structure and grease compounded body destroy, and create conditions for continuing to effective component extracting, further improve oil yield, also
The protein in oil meal and other compositions can be made to be processed further utilizing.
