Description
Technical field
The technical field, particularly fish oil based article that the present invention relates to edible fluid class deep removal pollutent removes (dioxin compounds) environmental pollutant, heavy metal and reduces oxide compound in fish oil, superoxide etc.
Background technology
Timnodonic acid (EPA), Decosahedaenoic acid (DHA) belong to omega-3 polyunsaturated fatty acids (PUFA), be can not be synthetic in body indispensable fatty acid, there is different physiological roles, wherein EPA has prevention coronary heart disease, hypotensive, Ginseng Extract, prevention of arterial is atherosis and cerebral thrombosis, the physiologically active such as anticancer, can be applicable in the food of preventing cardiovascular disease; And DHA can significantly promote baby power grow, improve cerebral function, improve memory, be called as " DHA (docosahexaenoic acid) ", can be applicable in baby's intelligence-improving food.
Many chloros hexichol-p-Dioxins (Polychlorinated dibenzo-p-dioxins, PCDDS) and many chloros diphenylene-oxide (Polychlorinated dibenzofurans, PCDFs) be conventionally generically and collectively referred to as Dioxins, they are chloro tricyclic aromaticss, 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 approximately has 30 kinds of materials that are considered to human health to have significant damage.Wherein 2,3,7,8-tetrachloro is maximum in current known compound toxic for dibenzo-p-Dioxins (TCDD), and its toxicity, than also malicious more than 1000 times, potassium cyanide, is called as " poison in century ", and experimentation on animals indicates that it has strong carinogenicity, by international cancer center, is classified as one-level cancer material.And Dioxins 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 accumulation in vivo, and hard degradation, belongs to persistent pollutant, once enter human body, all difficult eliminatings in 10 years.It produces source has from the organic burning of nature, but it is particularly serious to be mainly that the contained Dioxins of waste, the chemical race of discharging in Industrial processes and city burning mode are processed the Dioxins pollution on the environment that domestic waste produces, according to the report of EPA's report, tellurian 90% Dioxins is because mankind's activity causes at present.Meanwhile, in food, Dioxins is huge to harm, and the mankind more than 90% are by Food Contact Dioxins, especially by using meat product, milk-product, fish and shellfish etc.The quality of fish oil liquid matter is directly determining its value and application.Therefore high-quality fish oil, not only requires its physical and chemical index to meet specified range as acid value, color, peroxide value etc., the more important thing is strict control wherein pollutent as the content of the polychlorobiphenyl such as Dioxins, class Dioxins (PCBs), heavy metal etc.There are some researches show that dioxins concentration is less than fish oil that 0.4pg/kg, PCBs content be less than 4.5 μ g/L and adds to after edible in bread and can effectively reduce hyperlipidemia.European countries pay attention to especially to this pollutant, fish oil class related products has strict testing process, and China is because fish oil goods are started late, lack corresponding technology and standard, to problems, pay attention to relatively backward, but along with raising and the attention to food safety of domestic people's living standard, problems also obtains everybody and more and more payes attention to.How to pass through hi-tech means, improve fish oil liquid matter, strengthen fish oil range of application, just day by day by numerous scientific workers, domestic and international enterprise, paid close attention to, 21 century starts deep sea fish oil and has obtained significant progress at field of food, field of health care products and medicine field.
Fish oil purification refine is mainly by physics lift-off technology means such as short distance molecule rectifying at present.The rectifying of short distance molecule is a kind of under high vacuum (<10Pa) condition, and the molecule being evaporated on hot face arrives condensing surface through short as far as possible distance and carries out condensation, thereby realizes the still-process of liquid-liquid separation.When the distance of hot face and condensing surface be less than or equal at operation vacuum and temperature be evaporated the mean free path of molecule time, this still-process is also referred to as molecular distillation.From the correlative study of Julshamn etc., can learn, molecule rectifying or the rectifying of short distance molecule can for fish oil Pesticide Residues DDT with and the separation of meta-bolites, yet in this kind of method, it removes and on pollutent, is limited to 65% accompany 25% VITAMIN and runs off, yet 65% pollutant removal cannot meet industrial demand.In addition, Anthony etc. have reported that vacuum stripping or film rectifying are used for removing grease or the chloride hydro carbons of fluid, this kind of method only just can reach effective separation of pollutent when high temperature, then for fish oil high temperature, easily causes oxidation, polymerization or the side reaction of Fish oil.Jiri Comlik etc. has studied the method that water vapour is peeled off the free acid in physics table oil and molecule rectifying, yet that physical refining can obtain the fluid physics rectifying of better quality is very complicated and expensive.In the method for patent WO9524459, first by saturated fatty acid three ester esters and unsaturated fatty acids three ester transesterification reactions, then products therefrom is removed to pollutent by the rectifying of multistep molecule, in this technical process, used enzyme catalyst to be unfavorable for the production of Fish oil.Norway Pronova biotech company adopts fish oil extract as ' clean-out system ', by molecule rectifying lift-off technology, Fish oil be can effectively remove and cholesterol, toxaphene and dioxin contamination thing comprised, 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 need to obtain that pure their acquisition obviously exists certain difficulty not containing the lower boiling fish oil of the pollutents such as PCDF, PCDD, Dioxins, need to first obtain oligosaprobic fish oil and then through rectifying repeatedly, obtain low boiler cut.How the current domestic research and development without correlation technique, control the content of pollutent in the finished product by buying low pollution Fish oil crude oil, so development of new technology purifying fish oil removes the pollutent such as Dioxins in fish oil and has bright prospects.
