Description
Technical field
The present invention relates to krill oil extract field, more particularly, to a kind of low unsaponifiable matter antarctic krill oil and
Preparation method.
Background technique
About 6.5~1,000,000,000 tons of the total biomass of krill, biological academic year can amount of fishing up to 100,000,000 tons, this year catches
The amount of obtaining is equivalent to whole world marine aquatic product year fishing total output.It is most important latent that krill has become world's ocean-going fishing industry
In fishery resources.Result of study shows moisture content 77.9%-83.1%, crude protein 11.9%-16.3% in the fresh sample of krill,
Crude fat 0.50%-3.6%.Polyunsaturated fat rich in ω -3 series frequently as functional food in krill lipid
Acid, Phospholipids, vitamin, astaxanthin etc..In krill lipid polyunsaturated fatty acid (PUFAs) content of ω -3 series compared with
Horn of plenty, especially eicosapentaenoic acid (EPA, 20:5), docosahexaenoic acid (DHA, 22:6) account for total fatty acids respectively and contain
15.0%-25.3%, 9.3%-21.2% of amount.Studies have shown that the polyunsaturated fatty acid master of ω -3 series of krill
It is present in phosphatide, compared with traditional fish triglycerides lipid, is more conducive to human body for polyunsaturated fatty acid
Absorption.Carotenoid substance also rich in krill lipid component, most important of which is that astaxanthin, ice
The every 100g of fresh krill about astaxanthin-containing 3-4mg.Astaxanthin can protect lipid material from oxidation, be resisted in nature
Oxidation and the elimination strongest natural pigment of free radical ability.The lipid extracted from krill has anti-oxidant, anti-aging, clear
Except different physiological roles such as free radical, reducing blood lipid, brain tonic and intelligence developments, and after measured, the lipid of krill will not generate any poison
Side effect, health-care efficacy is more comprehensive, is a kind of very wide functional health care food of development prospect.
But there is a problem of that unsaponifiable matter content is high after krill oil extract, unsaponifiable matter content is excessively high to will lead to south
Pole krill oil poor fluidity, the problems such as transparency is low, therefore the preparation method for needing a kind of low unsaponifiable matter antarctic krill oil is used
In the quality for improving antarctic krill oil.
Summary of the invention
It is an object of the invention to the high defects of the antarctic krill oil unsaponifiable matter content for overcoming the prior art to extract, and mention
For a kind of low unsaponifiable matter antarctic krill oil and preparation method thereof.
To achieve the above object, the present invention provides a kind of preparation methods of low unsaponifiable matter antarctic krill oil, including with
Lower step:
S1. ethanol solution and mixed liquor is uniformly mixing to obtain to slightly mentioning being added in antarctic krill oil, the ethanol solution
Concentration is 75~99%；
S2. the derivative of cyclodextrin and/or cyclodextrin is added into the mixed liquor, stirs and be obtained by filtration filtrate, with
The total weight for slightly mentioning antarctic krill oil is counted for 100%, and the additional amount of the derivative of the cyclodextrin and/or cyclodextrin is 5
~50%；
S3. vacuum distillation removing ethyl alcohol is carried out to the filtrate and obtains low unsaponifiable matter antarctic krill oil.
