Abstract
The present invention relates to a method for carrying out separation extraction on cottonseed oil and shortening a cottonseed oil separation extraction time by adding an extremely hydrogenated vegetable oil as a crystallization promoting agent, and uses of the extremely hydrogenated vegetable oil as the crystallization promoting agent in cottonseed oil separation extraction. According to the present invention, the extremely hydrogenated vegetable oil is added as the crystallization promoting agent during the cottonseed oil separation extraction process so as to shorten the cottonseed oil separation extraction time and obtain the liquid cottonseed oil meeting the liquid cottonseed oil freezing test requirements in GB1537-2003 (the oil sample maintains the clarified and transparent state for more than 5.5 h at a temperature of less than 0 DEG C), such that the time and the energy source cost are saved, and the economic benefits of the enterprise are improved.
Description
Technical field
The present invention relates to shortening cotton seed oil to carry the method for time, the fractionation method of Oleum Gossypii semen and pole
Degree hydrogenated vegetable oil is as the purposes of crystallization-promoter.Specifically, the present invention relates to passing through to add extremely
Hydrogenated vegetable oil Oleum Gossypii semen is carried out point to carry as crystallization-promoter, and thus shortens point carrying of Oleum Gossypii semen
Time.
Background technology
Cotton Gossypii is mainly grown in subtropical and tropical zones, the main place of production of Cotton Gossypii of China include Xinjiang,
Henan, Hebei, Jiangsu, Hubei, Sichuan, Shandong, Hunan and Zhejiang etc. save.Oleum Gossypii semen is
The oils and fatss refining from cotton seeds (Semen Gossypii), are the side-products of cotton planting industry.Oleum Gossypii semen is
One of important edible oil of China, is also one of edible oil of countries in the world simultaneously.Due to domestic cotton
The establishing in large scale of flower, Semen Gossypii yield very abundant.And, oil content is in known Semen Gossypii
9wt%-25wt%, and the nearly 40wt% of Cottonseed oil content that Semen Gossypii obtains after shelling.Contain in Oleum Gossypii semen
There is abundant essential fatty acid, wherein linoleic content highest, up to Oleum Gossypii semen total amount
44.0wt%-55.0wt%.It is known that linoleic acid can reduce the cholesterol level in blood of human body,
Be conducive to protecting health.Additionally, in Oleum Gossypii semen also the Palmic acid containing 21.6wt%-24.8wt%,
The Semen arachidis hypogaeae of the stearic acid of 1.9wt%-2.4wt%, the Oleic acid of 18wt%-30.7wt% and 0-0.1wt%
Acid.Human body is about 98wt% to the digestibility of Oleum Gossypii semen.
But, in Oleum Gossypii semen, also contain more satisfied fatty acid.Due to satisfied fatty acid fusing point and
Freezing point is higher, will separate out so that Oleum Gossypii semen becomes therefore at a temperature of lower slightly from Oleum Gossypii semen
Thick or even solidification, causes Oleum Gossypii semen to be restricted at the aspect such as application, transport and trade.Therefore,
It is necessary to produce Semen Gossypii liquid oil and the solid grease with high added value by dividing to carry, thus expanding
The range of application of Oleum Gossypii semen.According in gb 1537-2003 with regard to Semen Gossypii liquid oil refrigeration test requirement,
Liquid oil needs are still transparent clarification in chilled more than 5.5 hours in 0 DEG C of refrigeration test.Therefore,
The Semen Gossypii liquid oil how obtaining meeting above-mentioned CNS is always the research heat in this area
Point.
At present, the fractionation technology of oils and fatss mainly has dry fractionation, solvent method to divide and carries and surfactant
Method is divided and is carried.And be directed to Oleum Gossypii semen, then mainly adopt dry method crystallized abstract technique.Wherein, dry method knot
Brilliant fractionation technology comprises the steps: first to make oil fusing completely thus eliminating crystallization (that is, breaking crystalline substance),
Then by controlling cooling conditions to carry out crystallizing, growing the grain, subsequently by being filtrated to get liquid oil and solid
Body oils and fatss.
However, in existing Oleum Gossypii semen dry fractionation technique, generally requiring longer crystallization and support
The brilliant time.For example, in classical tirtiaux method fractionation technology, cotton seed oil proposes required crystallization
It it is more than 36 hours with rearing crystal time.Xie Zhijun etc. (Chinese oil, the 8th phase of volume 36,
The 18-20 page, 2011) the Oleum Gossypii semen dry fractionation being carried out by low temperature stirring at low speed mentioned
In technique, still contain in point extract oil obtained by only growing the grain is accomplished by 12-24h, and the method
There is the satisfied fatty acid (for example, the Palmic acid containing 21.42%) of high level.Meanwhile, in
In dry fractionation technique disclosed in state patent application cn 1869182a, crystallization and rearing crystal time summation are
24-36h.
Because traditional dry fractionation technique needs longer crystallization and rearing crystal time so that being unfavorable for
Industry energy conservation and cost control, accordingly, it would be desirable to develop when can shorten cotton seed oil and carrying further
Between dry fractionation technique.
Content of the invention
Carry the time for shortening dividing of Oleum Gossypii semen, and guarantee that point Semen Gossypii liquid oil raising meets state simultaneously
With regard to the requirement of liquid oil refrigeration test in family's standard, the present inventor is to Oleum Gossypii semen fractionation technology and oils and fatss
Crystallization process has made intensive studies, and result finds first: during cotton seed oil carries, passes through
Add deep hydrogenation vegetable oil as crystallization-promoter in Oleum Gossypii semen, can effectively shorten dividing of Oleum Gossypii semen
Carry the time, and be obtained in that simultaneously and meet the Semen Gossypii freezing test requirements document in national standard with regard to liquid oil cooling
Liquid oil, thus solving above-mentioned problem, completes the present invention.
Therefore, one aspect of the present invention provides and shortens the method that cotton seed oil carries the time, the method bag
Include following steps: add deep hydrogenation vegetable oil in Oleum Gossypii semen.
The present invention is used as crystallization-promoter by adding deep hydrogenation vegetable oil in Oleum Gossypii semen, and in Semen Gossypii
Keep liquid condition to carry out follow-up crystallization and growing the grain process in oil, subsequently pass through lock out operation (example
As filtered) obtain Semen Gossypii liquid oil and solid grease.Found by detection, by the method for the invention
The Semen Gossypii liquid oil obtaining freezing at 0 DEG C is still transparent clarification in more than 5.5 hours, meets national standard
In with regard to Semen Gossypii liquid oil refrigeration test require.
Crystallization-promoter as herein described is to process Vegetable oil lipoprotein through refine, hydrogenation, ester exchange process
The deep hydrogenation vegetable oil obtaining, or be that the Vegetable oil lipoprotein of refine is obtained through hydrogenation treatment
Deep hydrogenation vegetable oil.Wherein, as the iodine of the deep hydrogenation vegetable oil of crystallization-promoter of the present invention
Valency is less than 5g i2/100g.
Another aspect of the present invention provides the fractionation method of Oleum Gossypii semen, and methods described comprises the steps:
(1) Oleum Gossypii semen is conveyed in crystallizer, in crystallizer, then adds deep hydrogenation plant
Oil, obtains rich mixture, and rich mixture is heated to being completely melt；
(2) following first stage cooling is carried out to the rich mixture after fusing in step (1),
With 0.2-70 DEG C/h of rate of cooling, described mixture is lowered the temperature through the stirring of 0.5-10 hour
To 3-20 DEG C, obtain the first cooling mixture；Subsequently, following the is carried out to the first cooling mixture
Two-stage lowers the temperature, with 0.05-20 DEG C/h of rate of cooling, by the first cooling mixture through 0.5-10
The stirring of hour is cooled to 0-10 DEG C, obtains the second cooling mixture；Then, start with the second fall
Warm mixture carries out growing the grain；
(3) to complete crystallize second cooling mixture carry out separate, thus obtain Semen Gossypii liquid oil and
Semen Gossypii solid grease.
