Abstract
The invention discloses a kind of extracting method of krill oil, comprise the following steps：Liquid is collected after frost microwave thawing processing is repeated after krill body surface moisture is dried up；Krill is made after the quick-frozen powder of krill to ultrasonic disruption processing after being well mixed with liquid I and obtains mixture II；The centrifugal treating of mixture II is obtained into residue I and liquid III；The instantaneous differential pressure flash distillation process of residue I is obtained into liquid IV and residue II；Residue II is squeezed into processing and obtains primary krill oil and residue III；Digested after residue III, liquid and liquid III are mixed into acquisition mixture III and centrifugal treating obtains the secondary krill oil of organic solvent extraction acquisition after enzymolysis liquid；Krill oil is refined after secondary krill oil, liquid IV are mixed into centrifugation removal of impurities water removal with primary krill oil.The recovery rate of the krill oil of the inventive method is high, the active component that can be effectively retained in krill oil, and the nutritive value of the product finally obtained is high, and organic solvent-free remains.
Description
Technical field
The present invention relates to bioactive substance and functional food factory formula technical field, more particularly to a kind of krill
The extracting method of oil.
Background technology
Krill aboundresources, growing environment is without industrial pollution.Krill oil is from krill (Euphausia
Superba the lipid of extraction, main component include in)：Glyceride, phosphatide, astaxanthin, sterol etc..Contain simultaneously in krill oil
Natural antioxidant astaxanthin, content up to 100mg/kg~300mg/kg, its oxidation resistance be significantly larger than vitamin E,
The materials such as lycopene, it is referred to as the most strong natural materials of antioxidation activity.It is existing research be proved krill oil rich in it is a variety of not
Saturated fatty acid, wherein long-chain omega-3 polyunsaturated fatty acids EPA and DHA content are up to 15.86%.Different from fish oil and fish liver
Oily ω -3 triglycerides form, the omega-fatty acid of krill oil are attached on phosphatide, this long-chain polyunsaturated fatty acid phosphatide
Bioactivity compound molecule small intestine can be directly entered after by stomach fully absorbs, add bioavilability, and finally
Improve ω -3: ω -6 fatty acid proportion.And krill oil intrinsic natural powerful antioxidant astaxanthin be also attached to phosphorus
Fat, so as to generate more stable lasting antioxidant effect.Shown according to experiment, the compound sub life of krill oil bioactivity
Thing availability is 95%~98%, and the bioavilability of fish oil only 61%~64%, and what main cause was that krill oil contains is phosphorus
Fat aliphatic acid, and almost 100% triglycerides that fish oil contains.Research shows：Krill oil (2g/d) can increase obese people
EPA and DHA concentration in blood, positive effect are said higher than taking herring oil (2g/d) and taking olive oil (2g/d) amplification
Understand that krill oil has good absorbability in human body；And after measured, krill oil does not produce any toxic side effect.
The extracting method of domestic and international krill oil mainly has：Organic solvent method, enzymolysis assisted extraction method, supercritical fluid extraction
The methods of, compared with other method, organic solvent method has that technique is simple, extraction efficiency is high, low cost and other advantages, is still industry
Change the most frequently used method, but shrimp sauce is extracted using the method for organic solvent as raw material using full shrimp and problems be present：It is organic molten
Agent extraction can have problem of solvent residual unavoidably, have impact on the utilization of krill protein, and other nutritional ingredients are damaged,
It has impact on making full use of for krill resource.
The content of the invention
It is an object of the invention to solve at least the above, and provide the advantages of at least will be described later.
It is a still further object of the present invention to provide a kind of extracting method of krill oil, the recovery rate of the krill oil of this method
Height, the active component that can be effectively retained in krill oil, the nutritive value of the product finally obtained is high, and organic solvent-free remains.
In order to realize according to object of the present invention and further advantage, there is provided a kind of extracting method of krill oil, bag
Include following steps：
Step 1: carrying out body surface moisture drying in 3 hours to it after krill fishing, and collect the liquid I of blowout；
Step 2: the krill frost processing after body surface is dried up, is handled, regelation of laying equal stress on freezes using microwave thawing afterwards
Handled 2-3 times with microwave thawing；
Step 3: collect the liquid after evaporating and cool down in microwave thawing processing procedure；
Step 4: the quick-frozen rear pulverization process that carries out of the krill of step 3 is obtained into the quick-frozen powder of krill；
Step 5: by volume 2:1-2 ratio is added to be well mixed after liquid I into the quick-frozen powder of the krill and obtained
Mixture I is obtained, the mixture I is carried out into ultrasonic disruption processing obtains mixture II；
Step 6: mixture II is carried out into centrifugal treating obtains residue I and liquid III；
Step 7: the instantaneous differential pressure flash distillation process of residue I is obtained into liquid IV and residue II, wherein instantaneous differential pressure flashes
