Description
Technical field
Oxide, peroxide etc. that the technical field, particularly fish oil based article that the present invention relates to edible fluid class deep removal pollutant remove (dioxin compounds) environmental contaminants, heavy metal and reduce in fish oil.
Background technology
Eicosapentaenoic acid (EPA), docosenoic acid (DHA) belong to omega-3 polyunsaturated fatty acids (PUFA), it is the essential fatty acid that can not synthesize in body, there is different physiological roles, wherein EPA has prevention coronary heart disease, hypotensive, dispelling fatigue, prevention of arterial are atherosis and cerebral thrombus, the physiologically active such as anticancer, can be applicable in the food of angiocardiopathy preventing; And DHA can significantly promote baby power grow, improve cerebral function, improve memory, be called as " docosapentaenoic acid ", can be applicable in baby's intelligence-improving food.
Many chloros hexichol-p-dioxin (Polychlorinated dibenzo-p-dioxins, and polychlorinated dibenzofurans (Polychlorinated dibenzofurans PCDDS), PCDFs) usually dioxin is generically and collectively referred to as, they are chloro tricyclic aromatics, because the replacement number of chlorine atom is different with position, form numerous compound.What be identified at present has 419 kinds more than, wherein about has 30 kinds of materials being considered to have human health significant damage.Wherein 2,3,7,8-tetra-chloro dibenzo-p-dioxin (TCDD) is maximum at current known compound Poisoning, and its toxicity ratio potassium cyanide also wants poison more than 1000 times, is called as " poison in century ", and zoopery indicates that it has strong carcinogenicity, be classified as one-level cancer material by international cancer center.And dioxin is distributed widely in global environment medium, its stable chemical nature, be difficult to be degraded by microorganisms, being proved this compounds can enrichment in food chain, it is very easy to accumulate in vivo, is difficult to degraded, belongs to persistent pollutant, once enter human body, all difficult eliminating in 10 years.It produces source has from the organic burning of nature, but the dioxin pollution on the environment that the generation of mode process domestic waste is burned in the dioxin contained by the discarded object mainly discharged in industrial processes, chemical race and city is particularly serious, according to the report of EPA's report, tellurian 90% dioxin is because mankind's activity causes at present.Meanwhile, in food, dioxin is huge to harm, and the mankind more than 90% are by Food Contact dioxin, especially by use meat products, dairy products, fish and shellfish etc.The quality of fish oil liquid matter directly decides it and is worth and application.Therefore the fish oil of high-quality, not only require that its physical and chemical index meets particular range as acid value, color, peroxide value etc., the more important thing is strictly control wherein pollutant as the content of the Polychlorinated biphenyls such as dioxin, class dioxin (PCBs), heavy metal etc.There are some researches show dioxins concentration be less than fish oil that 0.4pg/kg, PCBs content is less than 4.5 μ g/L add to edible in bread after effectively can reduce high fat of blood.European countries pay attention to especially to this pollutant, fish oil class Related product has strict testing process, and China starts late due to fish oil goods, lack corresponding technology and standard, backwardness is relatively paid attention to problems, but the raising along with domestic people's living standard and the attention to food security, problems also obtains everybody and more and more payes attention to.How by high-tech means, improve fish oil liquid matter, strengthen fish oil range of application, just day by day by numerous scientific workers, both at home and abroad enterprise pay close attention to, 21 century starts deep sea fish oil and obtains significant progress at field of food, field of health care products and medicine field.
Current fish oil purification refine is mainly by physics lift-off technology means such as short distance molecule rectifying.The rectifying of short distance molecule is a kind of under high vacuum (<10Pa) condition, heating surface is arrived cryosurface by the molecule evaporated through distance short as far as possible and carries out condensation, thus realize the still-process of liquid-liquid separation.When the distance of heating surface and cryosurface is less than or equal to the mean free path by vapor molecule operated at vacuum and temperature, this still-process is also referred to as molecular clock.Can learn from the correlative study of Julshamn etc., molecule rectifying or the rectifying of short distance molecule may be used for the separation of fish oil Pesticide Residues DDT and its metabolite, but in this kind of method its remove the pollutant upper limit be 65% accompany 25% vitamin loss, but the pollutant removal of 65% cannot meet industrial demand.In addition, Anthony etc. report vacuum stripping or film rectifying for removing chloride hydro carbons in grease or fluid, this kind of method only just can reach effective separation of pollutant when high temperature, then easily cause the oxidation of Fish oil, polymerization or side reaction for fish oil high temperature.Jiri Comlik etc. have studied the method that steam peels off the free acid in physics table oil and molecule rectifying, and physical refining can obtain the fluid of better quality but physics rectifying is very complicated and expensive.In the method for patent WO9524459, first by saturated fatty acid three ester ester and unrighted acid three ester ester exchange reaction, then products therefrom is removed pollutant by the rectifying of multistep molecule, in this technical process, employ the production that enzyme catalyst is unfavorable for Fish oil.Pronova biotech company of Norway adopts fish oil extract as ' cleaning agent ', effectively can remove Fish oil by molecule rectifying lift-off technology and comprise cholesterol, toxaphene and dioxin contamination thing, the PCB total amount of pollutant can reduce to 7.78 ng/g from 427ng/g, PCDD total amount can reduce to 0.83 pg/g from 3.49pg/g, and PCDF total amount can reduce to 1.82 pg/g from 29.6 pg/g.But the method needs to obtain that pure their acquisition obviously exists certain difficulty not containing the low boiling fish oil of the pollutant such as PCDF, PCDD, dioxin, need first to obtain oligosaprobic fish oil and then obtain low boiler cut through repeatedly rectifying.How the current domestic research and development without correlation technique, control the content of pollutant in final products by buying low stain Fish oil crude oil, therefore development of new technology Purified fish oil to remove in fish oil the pollutants such as dioxin and has bright prospects.
