Skill.
Background technology
Semen Maydis oil（Fructus Maydis oil）In except also containing Vitamin E, sterol, spiny dogfish containing abundant unsaturated fatty acid
The abundant neutraceutical active ingredients such as alkene, polyphenol, are the first-elected health care vegetable edible oils of international food and agricultural organization.But due to me
State's Semen Maydis oil processing starting evening, scope of the enterprise are little, and capacity for technological innovation is low, and current Semen Maydis oil is produced and refining techniques is applied mechanically substantially
, there are many deficiencies, after high temperature squeezing, generally carry out the tradition such as degumming, deacidification, decolouring, deodorize, dewaxing in the technique of conventional grease
Refinery practice liquefaction, causes Semen Maydis oil production overprocessing, and nutritive loss is serious, while generally existing color reversion is serious and funguses are malicious
Plain residue problem, becomes an industry difficult problem.
At present, the extracting method of Fructus Maydis oil has milling process, solvent extraction method, water extraction.Milling process can keep producing
The flavour of product, but high labor intensive, high cost, power consumption are greatly, and, micro-nutrient composition and work in loss Semen Maydis oil
Property material, the refinery practice of high intensity can increase the risk of the harmful substances such as trans fatty acid generation simultaneously.By comparison, leach
Method production efficiency is high and residual oil content is low.But solvent extraction method also has weak point:Equipment is more, investment is big；Crude oil complicated component, needs tight
The refining treatment of lattice, oily flavor loss are big；The degeneration in high temperature removing process of the wet dregs of rice is big；Using organic solvent, work is increased
The triviality of skill, the safety for reducing production, the pollution for causing environment, in product oil, residual minim organic solvent is to the mankind
Health is unfavorable.Although water extraction has the advantages that uniqueness than traditional milling process, solvent extraction method, can be by oil and protein same time-division
From, and gentle processing conditionss make protein keep higher nutritive value and functional character, make pigment and other Toxics again
Matter is dissolved in water and removes however, the mechanical shear stress that applies to oil plant of water extraction and calendering force are not enough to thoroughly destroy plant tissue
Cell wall and cause that oil yield is low, protein recovery is not high, in particular for oil yield during oil content relatively low oilseed
Very low, part oil is combined with protein, makes product easily oxidative rancidity.
The content of the invention

Relative analyses are tested
1. the crude oil index of quality is determined：
Semen Maydis oil crude oil using Enzymatic Extraction, plain press technique are obtained crude oil and 1 gained crude oil of the present embodiment and are carried out
The index of quality is determined, and table 1 is obtained.
The 1 crude oil index of quality of table is determined
By relative analyses as can be seen that using the crude oil obtained by low temperature pressing technology provided by the present invention, although still not
Oxidation stability that can be high as the crude oil of aqueous enzymatic extraction, but compared to traditional squeezing process, there has been very big carrying
It is high.1 acid number of the present embodiment and peroxide value are relatively low, with preferable crude oil quality.
2. test of the Semen Maydiss oil decolorization of the present invention with different proportion activated carbon and activated decoloration effect：
The desolventing technology of production method of the present invention is adopted for research, by imitating using different proportion activated carbon and activated decoloration
The comparison of fruit, is obtained table 2.
The comparison of 2 different proportion activated carbon of table and activated decoloration effect
As can be seen that the ratio of activated carbon affects little to decolorizing effect, therefore the ratio for adopting amount minimum, i.e., 0.1%；From activity
The ratio of hargil sees, with the increase of amount, decolorizing effect has been strengthened, but 3% active hargil amount and 4% active hargil amount its
Decolorizing effect almost, therefore according to cost consideration, should adopt 3% active hargil amount.It is same what is compared to last decolorizing effect
When, also to lovibond test meter colorimetric is carried out with the color after activated decoloration and activated carbon decolorizing.With 3% He of active hargil
As a example by activated carbon 0.1%, after active hargil 3% decolourizes, lovibond test is：Yellow 10.0, red 1.1, ash 1.0, and passing through

Oil absorbency average out to 12% during color, and oil absorbency average out to 10% of the activated carbon of 0.1%-0.5% when decolourizing.
Oil absorbency average out to 12% when experimentation, the activated decoloration of 1%-4%, and the work of 0.1%-0.5%
Property charcoal decolourize when oil absorbency average out to 10%.Wherein, active hargil 3% and activated carbon 0.1% are optimum proportioning.Reach in experiment
To the simple activity hargil and active hargil required for identical decolorizing effect and the price comparison of the mixture of activated carbon, draw
It is low with the Costco Wholesale of Mixture of Activated Carbon using active hargil.
3. the comparison of Semen Maydiss oil decolorization normal pressure and effect of easing stress at different temperatures：
Semen Maydis oil is easily aoxidized at high temperature, below experimental analysiss prove under different temperature and pressures, to Semen Maydiss oil decolorization
Impact.The desolventing technology of production method of the present invention is adopted for research, under using different temperatures and pressure, to desolventing technology
Impact, be obtained table 3.
The decolorizing effect of normal pressure and decompression under 3 different temperatures of table
As shown in Table 3, see on the whole, preferably, from the point of view of temperature, 90 DEG C is optimum temperature to the lower decolorizing effect of decompression.Under normal pressure
Color partially red phenomenon occurs during high temperature, this is aoxidized due to some compositions in oil at high temperature.
4. Fructus Maydis oil of the present invention is determined with traditional handicraft Fructus Maydis oil nutritive index：
Experimental analysiss compare system with conventional corn oil nutrient inventory through the Semen Maydis oil that embodiments of the invention 1 are produced below
Obtain table 4.
4 embodiment 1 of table is compared with conventional corn oil nutrient inventory
It can be seen that the content of Semen Maydis oil Squalene, β-sitosterol and Vitamin E is substantially high obtained in production technology of the present invention
In general Semen Maydis oil, the nutritional labeling being effectively kept in Fructus Maydiss, the work(with auxiliary blood fat reducing, enhancing immunity
Energy.
5. fungal content detection after Fructus Maydis oil mycotoxin removing process of the present invention is removed with traditional handicraft：
Experimental analysiss are produced through 1 mycotoxin removing process of embodiments of the invention below Semen Maydis oil and adopt traditional work
Skill Semen Maydis oil mycotoxin levels are relatively obtained table 5.
5 embodiment 1 of table is compared with conventional corn oil mycotoxin levels
It can be seen that Semen Maydis oil main fungal toxin obtained in mycotoxin removing process production of the present invention is basically reached and is not detected
Level, hence it is evident that better than conventional corn oil.
