Meanwhile, compared with average oil processing, the method of the invention has much lower energy consumption and can better maintain the quality of the made fish oil.

Description

Spot fork-tail catfish oil and preparation method thereof
Technical field
The present invention relates to a kind of method of refining spot fork-tail catfish oil, the method for refining spot fork-tail catfish oil in the leftover bits and pieces that specifically refers to from fillets of ictalurus punctatus processing, produce.
Background technology
Channel catfish claims the ditch gill again, gains the name because of there is obvious irregular black splotch its health both sides.Channel catfish is the main cultured freshwater fish of the U.S. and since channel catfishes have adaptability strong, easily raise, advantages such as no spur and delicious meat, and become breed highly visible and object is angled in trip.China introduced from the U.S. first in 1984, and at present domestic existing 24 provinces and cities culture, and form the main economic industry of export processing fillet.But further expansion along with process scale, produced increasing fillets of ictalurus punctatus processed side product, comprise fish head, fin, tail and internal organ and fish tallow, main at present the diet of these leftover bits and pieces as carving, fox etc., transportation and preservation are all very difficult, and be worth low, the enthusiasm of dampening the raiser.
Therefore, solve the problem of complex utilization of the leftover bits and pieces that processes the fillets of ictalurus punctatus generation, for widening the channel catfish industry, the added value that promotes channel catfish is significant.
Aspect the utilizing of fish scrap, Shandong Medical University and Yantai can head factory (utilizing fish scrap to extract curative effect fish oil technology) are raw material with the can fish scrap, under alkalescent and an amount of salt condition, prepare fish oil and fish meal by operations such as boiling, squeezing, fatty acid sodium salt, secondary saponification and cryogenic freezings, but this method uses industrial alcohol to make solvent, complex procedures, the fish oil quality that obtains is not high, can't satisfy the demand of medical treatment, healthcare industry." southern aquatic products " paper in 2007 " research of extracting fish oil from the rotten leftover bits and pieces of fish " discloses a kind of leftover bits and pieces with the rotten processing of fishes such as red coat, and to be raw material prepare the method for fish oil by hydrolysis, technology such as saltout, this method is a raw material with the fish gruel mainly, and product quality only can reach the requirement of crude fish oil secondary." research of supercritical carbon dioxide extracting Turtle Oil " of " Chinese oil " 2003 28 10 phases of volume discloses and extracted the method for separating Turtle Oil from soft-shelled turtle, but soft-shelled turtle is a reptile, the composition and the raw material proterties that are oil all have bigger difference with fish, and supercritical technology cost height and be not suitable for industrialization production.By retrieval, relevant fish oil production technology also has " Food Science " " extraction of gem fish oil of 2006 27 7 phases of volume, the analysis refining and aliphatic acid is formed ", " ammonia process extracts the research of fish oil technology " of " Chinese marine drug " 2002 21 3 phases of volume, " traditional light alkali hydrolysis method extracts the research of fish oil technology " of " Mountain Western Medicine S University's journal " 2000 31 6 phases of volume, " preparation of tilapia oil and the fatty acid compositional analysis thereof " of " Shandong fishery " 2005 22 7 phases of volume, " craft discussion of comprehensive utilization dace processing fent fish head " of " Guangzhou food industry science and technology " 1999 15 1 phases of volume, and patent document " a kind of eel animal oil and production method thereof " (patent No. 200410026812.X) or the like, but no matter these methods are in technology, raw material, all exist than big difference and deficiency on the product with this method.
Summary of the invention
For solving the problem of complex utilization of the byproduct (leftover bits and pieces) in the fillets of ictalurus punctatus processing, the inventor invents out a kind of preparation method who refines spot fork-tail catfish oil from the leftover bits and pieces that fillets of ictalurus punctatus processing produces finally through a large amount of production practices.
The preparation method of spot fork-tail catfish oil of the present invention comprises following step:
(1) producing of the thick oil of channel catfish comprises selection, classification, the fragmentation of (1-a) leftovers of ictalurus punctatus.Leftover bits and pieces is divided three classes, and a class is the fish tallow in the channel catfish body, and a class is parts such as the head, fin, tail of channel catfish, and a class is the internal organ of channel catfish in addition; (1-b) separate after most of fish oil boiling is come out carrying out boiling after the above-mentioned classification fragmentation, aqueous phase discarded, residue obtain thick oil.
(2) will go up the thick oil that step produces and make with extra care, comprise: (2-a) alkali-refining deacidification, adopt the low temperature concentrated base to carry out alkali-refining deacidification, add salt water, leave standstill, centrifugation goes out soap stock; (2-b), washing removal of impurities; (2-c) dehydration and decolorization removes raw meat.
For edible fish oil, need further to reduce the acid value of fish oil and the odoring substance in the fish oil, also need carry out following process steps: (2-d) depickling deodorizing, fish oil after the said process processing is placed the deodorizing pot, begin when being vacuum-drawn against absolute pressure to heat up for 0.01-0.02MPa, when being warming up to 140-160 ℃, feeding pressure is that the steam of 0.4-0.7MPa makes the fish oil atomizing, and continue to be warming up to 180-280 ℃, absolute pressure is 0.0025--0.004MPa, ceaselessly vacuumize simultaneously, be incubated cooling after 2-4 hour, stop vavuum pump when temperature is reduced to 70--95 ℃, continue to be cooled to 30--50 ℃;
To place freezing pot through the fish oil of above-mentioned depickling deodorizing, and carry out (2-e) freezing degreasing again, temperature is controlled at 0--6 ℃, and up to micro-precipitate occurring, after continuing freezing and keeping more than 25 hours, filtration promptly obtains high-quality health care and medical fish oil.
The spot fork-tail catfish oil that said process makes, moisture and volatile matter content≤0.1%, acid value is≤1.0mgKOH/g, peroxide value is≤6mmol/kg, impurity is≤0.1%, includes the oleic acid, the linoleic acid of 7-11%, the leukotrienes of 3-6%, the C of 1-5% of DHA, 20-27% of EPA, the 5-12% of 6-10% 20:4C with 15-22% 16:1, total insatiable hunger is closed content of fatty acid and is higher than 70%.
By the spot fork-tail catfish oil that said method makes, find that after testing wherein the aliphatic acid kind utmost point and abundant has more than 50 kinds, total insatiable hunger is closed content of fatty acid more than 70%, and contains abundant cupreol, EPA and DHA.DHA is commonly called as brain gold, has higher medical treatment, health care, and therefore, spot fork-tail catfish oil is the another important meals source of functional fatty acid, and market potential is huge.
Preparation method of the present invention inserts water circulating vacuum pump and oil-sealed rotary pump at the top of depickling deodorizing pot, than and the steam jet pump that general oil prodution industry adopts and the vacuum draw of water circulating vacuum pump, not only has characteristic of low energy consumption (only being the 10-25% of former energy consumption), also improved simultaneously vacuum greatly, under the effect of sprayer unit, increased the surface area of fish oil, make that the efficient of depickling deodorizing is higher, shortened the time of depickling deodorizing, guaranteed that the quality of product oil is better.
