Description
Technical field
The invention belongs to fatty acid to extract field, be related to a kind of process using sea eel and remain material production polyunsaturated fatty acid
Method.
Background technique
Contain a large amount of polyunsaturated fatty acid (PUFA) in fish, it has plurality of health care functions, especially EPA, HMA
With prevention of arterial hardening and cardiovascular and cerebrovascular disease, be conducive to the development of children's early intelligence and the health cares function such as prevent brain aging
Can, currently, gradually ω -3 fish oil is widely used on the replenishers and hardening agent of food both at home and abroad.
The processing of sea eel can generate a large amount of processing byproduct, such as fish head, internal organ, fish-skin, and weight accounts for about raw material fish
50% or so.These by-products, especially internal organ, mostly for processing low value product or directly being abandoned as waste, both
It polluted environment, and cause the serious waste of resource.With science and technology and industrialized fast development, fish processing fent
Higher value application be increasingly taken seriously.Sea eel internal organ contain a large amount of phosphatide, unsaturated fatty acid, protein and vitamin
Deng, have greatly utilize space and utility value.Therefore, the utilization for studying polyunsaturated fatty acid in sea eel internal organ fish oil has
Help the regeneration of waste resource, there is biggish economic value.
Currently, the method for the extraction unsaturated fatty acid is also many from fish oil, such as Patent publication No is
A kind of method using gadus internal organ preparation high-purity marine products polyunsaturated fatty acid phosphatide disclosed in CN106632459, for another example
The extracting method of omega-3 polyunsaturated fatty acids in Turtle Oil disclosed in CN1986515.
Though the structure of fish is substantially similar, different fingerlings are directed to, composition, raw meat degree of fatty acid etc. are all different, benefit
It is used for sea eel with the extracting method of the polyunsaturated fatty acid phosphatide of other fish in the prior art, can be used for reference, but not
The polyunsaturated fatty acid phosphatide of desirable quality can be directly obtained.
Summary of the invention
The present invention provides a kind of method for producing polyunsaturated fatty acid, processes surplus material as raw material, to eel using sea eel
The surplus material of fish makes full use of, and is all substantially better than from recovery rate, purity, quality obtained mostly not using prior art extracting method
Saturated fatty acid.
The present invention adopts the following technical scheme that:
A method of surplus material production polyunsaturated fatty acid being processed using sea eel, is included the following steps:
(1) the surplus material of sea eel processing is cleaned, crushes, salt water is added, and obtains crushed material slurries；Salt water is added, preferred mass concentration is
10-15% can promote protein to separate with lipid, more conducively the extraction of fatty acid, improve recovery rate.
(2) decoloration deodorization processing is carried out to the crushed material slurries, is purified material；
(3) ethanol solution is added into purification material, is extracted 1-1.5 hours at 40-45 DEG C, suction filtration obtains filtrate；It extracts
Temperature it is too low, extract it is insufficient；
(4) filtrate is fractionated, recycles ethyl alcohol, remainder is fractionation component；
(5) 1mol/LKOH ethanol solution is added into the fractionation component, is saponified at being 85-90 DEG C in temperature；
(6) fish oil blend after saponification is taken out, HCl acidification is added, stirring is stood, and takes upper liquid；
(7) urea-ethanol solution is added into upper liquid, is handled 30 minutes at being 45-55 DEG C in temperature, then maintain temperature 45
It is included at DEG C 40 minutes, stands at least 12 hours at 5 DEG C later, filtering takes filtrate；
(8) by filtrate washing, drying, unsaturated fatty acid is obtained.
Preferably, urea-ethanol solution additional amount is 4-5 times of upper liquid volume.
Preferably, the w/v of urea in urea-ethanol solution, ethyl alcohol is 1:3.
Preferably, step (2) uses decoloration deodorization agent, the decoloration deodorization agent is to load the modified of deodorant compound bacteria to live
Property charcoal.
In above-mentioned technical proposal, using the modified activated carbon of load deodorant compound bacteria, it can be provided for deodorant compound bacteria attached
Carrier, keep its Function more stable.
Preferably, modified activated carbon is to be modified to it using resin, diatomite, active carbon, resin, diatomite
Weight ratio is 3-8:1:1.
Preferably, modified activated carbon method of modifying: it is resin melting, diatomite is added, compound grain is made after mixing evenly,
Compound grain is mixed with the active carbon of powdery again, is pelletized to get modified activated carbon.
Preferably, deodorant compound bacteria includes streptococcus lactis, lactobacillus bulgaricus, lactobacillus plantarum, saccharomycete.
Preferably, in step (7) a metallic, while urea-ethanol solution is added, microcrystalline cellulose is added.Addition is few
The microcrystalline cellulose of amount, so that damage condition is presented in urea tetragonal crystal during inclusion, this incomplete crystal has
Higher surface energy, easily forms hexagonal with the saturated fatty acid of chain, forniciform unsaturated fatty acid is then not easy shape
At crystal, to obtain the unsaturated fatty acid of high-content.
Preferably, the additional amount of microcrystalline cellulose is according to 50 g -55g are added in every liter of upper liquid.
By implementing above-mentioned technical proposal, the present invention processes surplus material as raw material using sea eel, extracts polyunsaturated fat
Acid solves the problems, such as the waste of largely surplus material resource, reduces environmental pollution that obtained polyunsaturated fatty acid recovery rate is higher,
Purity is higher, and simple process is easily controlled.
