Description
Technical field
The present invention relates to a kind of method that krill oil is extracted from krill, it is directed to preparation-obtained by this method
The krill oil product of low total arsenic content.
Background technology
Krill is distributed mainly on the free of contamination South Pole marine site of low temperature, is a kind of crustacean plankton, using algae as
Food, its reserves is huge, about 1,000,000,000 tons.Krill rich in multiple beneficial composition include ω -3 races aliphatic acid (EPA and
DHA), phosphatide, astaxanthin, linoleic acid, leukotrienes, palmitic acid etc., it is a kind of preferable natural health care, but due to South Pole phosphorus
Heavy metal arsenic (total arsenic) in shrimp containing 2-3ppm, it is higher that it extracts total arsenic (organo-arsenic and inorganic arsenic) content in gained krill oil
(general 7-10ppm), its inorganic arsenic are generally 0.05-0.10ppm, organo-arsenic 7-10ppm.Because the heavy metal arsenic of excess can be done
Disturb the eubolism of cell, influence breathing and oxidizing process, make cell occur lesion, therefore krill oil in food apply by
Limitation.
At present, on the market krill oil product its total arsenic content is higher, generally 7-10ppm, is also removed without krill oil
Report in terms of total arsenic.After the completion of the A of Chinese patent CN 102041166 are using the extraction extraction of nonpolar or weakly polar organic solvent
Krill oil add polar organic solvent and be enriched with, nitrogen or carbon dioxide remove polar solvent, its shortcoming to be nonpolar or
Low pole extraction efficiency is low.The A of Chinese patent CN 102405988 are using shearing extraction 1-4 times, and ethanol is solvent, nitrogen or two
Carbonoxide removes organic solvent, but ethanol is solvent, extraction time length, needs to soak before shearing, reduces extraction efficiency.China
The A of patent CN 101652462 report a kind of krill oil extracting mode of carbon dioxide supercritical extraction, although low temperature extraction is more
Help to retain benefit materials, but its extraction efficiency is not high, and high energy consumption, equipment cost are big.Chinese patent CN
The method that 1324394 A report acetone low temperature extraction krill oil, filter residue are extracted using ethanol for the second time, lipid grading extraction,
Slag recovering enzyme and protein, this technique is complex, and time-consuming and acetone can be to product quality for the dissolvent residual of solvent
And later stage application has an impact.The A2 of patent WO 2014/013335 report to be entered using ethanol to the krill oil for completing extraction
Row low temperature removes saturated fatty acid, the method for improving unrighted acid ratio, and beneficiating ingredient content is high in its product：EPA is high
In 22%, DHA higher than 10%, vegetable oil acid 3%-9%, astaxanthin 20-4000ppm, but there is not total arsenic content related data.
Other Li Dinglong etc., the method removed using composite to drink reclaimed water micro amount of arsenic was reported in 2007；Liu builds, in
The arsenic adsorbed using modified kaolin in water is reported within 2009, but arsenic is typically inorganic with arsenate and arsenite etc. in water
Form is present, and its content is not high and relatively easily removes, and the arsenic overwhelming majority in antarctic krill oil is deposited in the form of organo-arsenic
High in, its content, molecular weight is relatively large, and removing difficulty is high, and there has been no the xi phases for closing total arsenic removing in antarctic krill oil at present
Close report.
The content of the invention
The present invention is intended to provide a kind of krill oil product and its production method.This method can should comprehensively take into account production
Harmful components removal and the reservation of beneficiating ingredient in product.
Therefore, present invention firstly provides a kind of preparation method of low arsenic krill fluid composition, with the South Pole after crushing
Krill meal is raw material, is comprised the following steps：
(1) after washing raw material with ethanol water, extracted with ethyl acetate and ethanol according to the mixed solvent of arbitrary proportion；
(2) extract solution is with adsorbent arsenic removal；
(3) molecular distillation desolvation.
Further, the present invention also provides the low arsenic krill fluid composition obtained by the above method.
The preparation method complex optimum of the low arsenic krill fluid composition of the invention described above Feedstock treating and extraction remove
Miscellaneous technical process, the total arsenic content in antarctic krill oil is reduced by the way of advance washing and absorption are combined, simultaneously
The content of Hubeiwan such as ω -3 races aliphatic acid (EPA and DHA), phosphatide, astaxanthin etc. in krill oil is not destroyed.Extract solution is adopted
Desolvation is carried out with the mode of molecular distillation, effectively removes dissolvent residual.So as to obtain the low arsenic antarctic krill oil of high quality
Composition product.
Embodiment
The present invention is intended to provide the high quality Antarctic krill oil product of low arsenic.The excellent specific property of the product is entirely due to this hair
Bright advanced efficient preparation method is obtained.
The preparation method of low arsenic krill fluid composition of the present invention, using the euphausia superba powder after crushing as original
Material, including the step such as raw material washing, extraction, absorption arsenic removal and solvent removal.
Firstly, it is necessary to the euphausia superba powder as raw material is washed using ethanol water washing.Wherein, second used
Alcohol solution is the ethanol-water solution that ethanol weight/mass percentage composition is 10~50%；Wherein particularly preferred concentration of alcohol 30% is left
Right ethanol water.In the embodiment of washing, the mass ratio of raw material and ethanol water is 1:4~6.It is preferred that 1:5.
The washing typically continues 10~40min under the conditions of 25~30 DEG C.
Completing the raw material krill meal of washing will be entered by ethyl acetate and ethanol according to the mixed solvent of arbitrary proportion in next step
Row extraction.In specific embodiment, the mass ratio of the extraction step raw material and mixed solvent is 1:8~12.It is preferred that 1:10.
And the mixed solvent used in extraction step is ethyl acetate and ethanol according to volume ratio 3:7~8:2 mixing
Solvent.Ethyl acetate and ethanol are according to volume ratio 3~8:2 mixture, more preferred mixed proportion include but unlimited
In 6:4、7:3 and 8:2；Wherein, most preferably 7:3.
More specifically in embodiment, extraction is divided into be carried out twice, extracts about 1h every time.
After completing extraction, extract solution is needed with adsorbent arsenic removal.In embodiment, wherein described adsorbent is living
Property charcoal, diatomite, attapulgite or chitosan, and its material in source.The mass ratio of adsorbent and extract solution is 1:90~
110.It is preferred that use 1:100.
In the embodiment of absorption arsenic removal, adsorb under 50 ± 2 DEG C of temperature conditionss, operate at twice, every time about 1h.
After absorption arsenic removal, gained liquid is with molecular distillation desolvation.Specific operating parameter includes operating pressure 10Pa,
Temperature 60 C, inlet amount 2.0L/h.
In the preparation method of low arsenic krill fluid composition described by the invention described above, the group of the technical parameter of optimization
Close, the different preferable technical schemes on preparation method can be obtained.With suitable for different production environments and product demand
Under the conditions of production.The either a program of the preparation method of the low arsenic krill fluid composition, can prepare and meet this hair
The product of bright requirement.The purpose of another aspect of the present invention is then the low arsenic antarctic krill oil combination for protecting the above method to prepare
Thing.
As one of distinctive feature, there is low arsenic krill fluid composition of the invention extremely low controllable total arsenic to contain
Amount, is 0.5-2ppm.
In addition, effectively remained in raw material krill meal by the low arsenic krill fluid composition prepared by the above method
Other various Hubeiwans：According to weight/mass percentage composition, content of phospholipid 35-45%, content astaxanthin is up to more than 200ppm；
