Description
Technical field
The invention belongs to food processing technology field is and in particular to a kind of preparation technology of millet oil.
Background technology
Millet multiple provinces to the north of China the Yellow River are extensively planted, wherein Shandong, Hebei, Shanxi, Shaanxi, Liaoning, Inner Mongol
In recent years become major production areas.Endure and can float one layer " Miyou " above during milled congee and condense upon one layer of medicated porridge oil on pot face.The Qing Dynasty
Described in the supplementary Amplifications of the Compendium of Materia Medica that ZHAO Xue-Min is write, Miyou " black and thin person eats it, and one hundred days are fertile white " visible its also has whitening
The effect of.Qing Dynasty's physician's Wang Meng English then thinks " Miyou can be for ginseng soup " in his " occupying diet spectrum with breath ", because it and people
Ginseng equally has the effect of effect of strongly invigorating primordial QI, enhance immunity.China produces about 6,000,000 tons of millet per year, will produce Testa oryzae
600000 tons, and in modern agriculture, millet during processing Semen setariae, the side-product (Testa oryzae) of generation generally as
Fertilizer or feedstuff are processed, and the millet oil being rich in Testa oryzae is then by slatterning in vain；Show through modern study: millet oil
In containing abundant unsaturated fatty acid content up to more than 80%, also contain plant sterol (5%), phospholipid, tocotrienol, paddy
Tens kinds of natural bioactive ingredients such as dimension element, vitamin e, oryzanol is the family's chemical combination being made up of ten several sterols simultaneously
Thing can stop autologous synthetic cholesterol, the concentration of reduce serum cholesterol, blood circulation promoting, softening cardiovascular and cerebrovascular vessel, protection
Skin, has slow down aging, enhance immunity and improves the functions such as nervous system, it has higher nutritive value, and
After edible, absorbance reaches more than 90%.
Content of the invention
It is an object of the invention to overcome of the prior art not enough and provide a kind of process is simple, flow scheme design rationally,
Can make Testa oryzae turn waste into wealth, improve agricultural products added value, increase the income of peasant, the oils and fatss prepared have free
Content of fatty acid is few, oxidative chain reactions occur slow, good stability and are rich in the native oxidant such as vitamin e and plant sterol
A kind of preparation technology of millet oil.
The object of the present invention is achieved like this: this preparation technology comprises the steps:
Step one: quenched: Testa oryzae is carried out modifier treatment, make quenched after Testa oryzae moisture be 8%-16.5%, temperature is:
20℃-135℃；
Step 2: squeezing: make the Testa oryzae after modifier treatment in step one put in mechanical expression device and squeezed, after compacting
Obtain crude oil；
Step 3: filter: make the crude oil described in step 2 filter by filter, filter the bran slag in crude oil and cake foam, obtain
To crude oil；
Step 4: aquation degumming: make the crude oil in step 3 be delivered in oil water separator by oil pump and heated, after heating
Add the soft water of equality of temperature to carry out aquation in crude oil, after aquation is complete, carry out oil-water separation；Described heating crude oil is to 65 DEG C -95
DEG C, the addition of described soft water is the 9% of crude oil weight；
Step 5: vacuum dehydration: make the crude oil after oil-water separation in step 4 enter in vacuum hydroextractor and be dehydrated, after dehydration
So that oil temperature is cooled down in the state of vacuum, make rice oil；Vacuum in described vacuum hydroextractor is not less than
0.08mpa, the temperature in vacuum hydroextractor is 90 DEG C, and the time of vacuum dehydration is 3-4h；Described oil temperature is in the state of vacuum
Temperature after cooling is not more than 60 DEG C；The acid number of described rice oil is 15(koh)/(mg/g)；
Step 6: once freezing dewaxing: make rice oil in step 5 enter in crystallizer, cooled down under slow stirring, make bran
The oil temperature of oil is slowly uniformly down to 20 DEG C -25 DEG C in 60h-72h, then proceedes to be slowly stirred, and is keeping oil temperature inconvenience
Under the premise of carry out growing the grain, growing the grain is filtered with the leaf-type filter of precoated diatomite after terminating, and makes dewaxed oil；Described slow
Stirring and the stir speed (S.S.) that continues to be slowly stirred are: 10-13 rev/min, described rearing crystal time is at least 72h, described are filtered
When rice oil oil temperature be 20 DEG C -25 DEG C；
Step 7: decolouring: the dewaxed oil heat release described in step 6 is placed in vacuum decoloration pot to after 105 DEG C -115 DEG C,
Add decolorising agent, decoloured in the environment of vacuum is at least -0.085 mpa, make bleached oil；Described decolorising agent
Addition is the 4%-8% of dewaxing weight of oil；Described decolorising agent be active hargil, active hargil and activated carbon mixture it
One；In the mixture of described active hargil and activated carbon, the weight of activated carbon is the 4%-6% of active hargil weight；
Step 8: physical deacidification: the bleached oil in step 7 is heated, makes it in packed-type deacidification tower after heating
Row deacidification, the residual voltage of described filler formula extracting tower is: 100pa-500pa, and the bleached oil after described heating is 230 DEG C -260 DEG C,
Described bleached oil is less than 120 DEG C by the temperature after packed-type deacidification tower；
Step 9: deodorize: enter in deaerator after making the bleached oil after physical deacidification in step 8 be heated to 120 DEG C -140 DEG C
Row gassing, is further heated to 260 DEG C -280 DEG C after gassing to bleached oil, and the bleached oil after heating further enters into rustless steel
Carry out deodorize in filler deodorizing tower, obtain deodorizing oil；Residual voltage in described stainless steel helices deodorizing tower is less than 100pa；Logical
The deodorizing oil oil temperature crossing stainless steel helices deodorizing tower is 230 DEG C -260 DEG C；
Step 10: secondary freezing dewaxing: make deodorizing oil in step 9 enter in secondary crystallization tank, carry out cold under slow stirring
But, the oil temperature making deodorizing oil is slowly uniformly down to 20 DEG C in 70h-74h, then proceedes to be slowly stirred, and is keeping oil temperature not
Just carry out secondary growing the grain on the premise of, secondary growing the grain carries out secondary filter with the leaf-type filter of precoated diatomite after terminating, system
Become product oil；The stir speed (S.S.) being slowly stirred described in this step and continuing to be slowly stirred is: 10-13 rev/min, described secondary foster
The brilliant time is at least 72h, and the described oil temperature carrying out deodorizing oil during secondary filter is 20 DEG C.
Preferably, quenched in described step one is to be dried by dehydrator.
Preferably, the mechanical expression device in described step 2 is one of pressafiner or hydraulic squeezing press.
The present invention has process is simple, flow scheme design is reasonable, the time of producing is short, extraction ratio is high, technical process is safely controllable
Property oils and fatss free fatty acid content that is good, preparing is few, oxidative chain reactions occur slow, good stability, be rich in vitamin e and plant
The advantage of the native oxidant such as sterol.
Specific embodiment
