Abstract
The invention relates to a method for preparing fish oil and fish paste from internal organs of squids through subcritical extraction and enzymolysis coupling, and belongs to the field of processing aquatic products. The method disclosed by the invention utilizes a subcritical fluid extraction technique to extract the fish oil and the fish paste from fish wastes. The method comprises the following steps: step one, adopting subcritical fluid low-temperature extraction and an intelligentized PLC control technique to prepare the fish oil, conveying protein juice into a cooking reaction kettle, and adding composite flavored protease; step two, conveying the mixture of the protein juice and the composite flavored protease into a filter, finally drying the filtered mixture so as to obtain squid paste, and collecting and conveying the produced waste gases to a boiler for combustion. The production of squid wastes through subcritical extraction can directly extract processed wastes of fresh aquatic products, so that a dehydration and degreasing technology by a one-step method is realized, and besides, the fish oil and the fish paste are obtained. The defects of traditional technology equipment are avoided, and multi-functional purposes of solid liquid, liquid liquid, multiple solvents and the like of the equipment can be realized. The technique can be promoted and applied to the comprehensive utilization of the processed wastes of the whole aquatic products, so that an economic value is caused, and the problem of environmental pollution caused by fish meal production by a conventional dry method or a conventional wet method is solved.
Description
Technical field
The present invention relates to aquatic product manufacture field, if the preparation method of this kind of squid fish oil, fish cream.
Background technology
Fish pomace is used for greatly the production of fish meal.Fish meal production status must to heating raw materials slaking.This can discharge the effluviums such as hydrogen sulfide, ammonia, trimethylamine, methyl mercaptan, belongs to industry of keeping under strict control.But the method that now there is no is closed down this curing process fish meal and is produced.Because of the place to go that fish meal factory is fish pomace, and fish meal is again feed industry high-quality protein source.Subcritical fluid extraction application in plants essential oil, grape pip procyanidin etc. extract.By sci-tech novelty-search, subcritical fluids is extracted in the document that fish oil in fresh fish pomace and Fish protein scale up test at home and abroad publish and is had no report.This project achievement in research can utilize squid processing fent with cleaning.This not only improves the value of squid, for squid processing enterprise brings considerable economic benefit, and the discarded object that squid is processed all is utilized and becomes the higher fish oil of value and fish cream, solve the contaminated environment outstanding problem of local restriction processing of aquatic products Region Sustainable Development, social benefit is highly significant also.
Summary of the invention
The present invention utilizes fish oil, fish cream in subcritical fluid extraction technology extraction fish pomace, in the processing method of the raw material first step, adopt subcritical fluids low-temperature extraction, and adopt intelligent PLC control technology, obtained fish oil, then protein juice is sent into cooking reaction still, now add reaction reagent, heated rear feeding drier, obtains squid liver paste finally by drying, and sends in boiler after the gas sampling produced and burn.The production realizing subcritical abstraction squid leftover bits and pieces can directly extract fresh aquatic products processing leftover bits and pieces, realizes one-step method dewatering and defatting technique and obtains fish oil, fish cream simultaneously.Both overturned the drawback of traditional process equipment, the multifunctional usages such as the solid-liquid of equipment, liquid liquid, multi-solvent can have been realized again.This technology can apply the comprehensive utilization to whole disposal from fishery product processing, and the dry method or the production of wet method fish meal that solve routine while bringing economic worth cause problem of environmental pollution.
Described extractive technique is subcritical fluid extraction, nontoxic, harmless, and the biologically active prod of environmental protection, non-thermal technology, reservation extract does not destroy, is easy to and product separation.
Described enzyme is compound fertilizer production.
Compared with existing technology, simultaneously advantage of the present invention can realize one-step method dewatering and defatting technique to obtain fish oil, fish cream, both overturned the drawback of traditional process equipment, and can realize again the multifunctional usages such as the solid-liquid of equipment, liquid liquid, multi-solvent.
Accompanying drawing explanation
Accompanying drawing is front view of the present invention;
Accompanying drawing explanatory memorandum: 1. subcritical abstraction device; 2. cooking reaction still; 3. exhaust processor; 4. filter; 5. drying machine; 6-8. pump.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in the figure, the device device of a kind of subcritical fluid extraction described in the present embodiment and enzymolysis coupling fish oil processed, fish cream from squid viscera, comprises subcritical abstraction device 1, cooking reaction still 2, filter 5, drying machine 4 and exhaust processor 3.Squid viscera is put into extractor 1 and is extracted, and just can obtain fish oil, and then squid protein juice is sent into slaking in cooking reaction still, and add compound fertilizer production enzymolysis, reactor outer wall cooling water circulation cools.Just obtained fish cream after filtration with after drying again, utilized the waste gas produced in wasted treatment device processing process simultaneously, tail gas is sent in boiler and is burnt.
Claims (4)
1. produce fish oil, the method of fish cream, it is characterized in that utilizing subcritical fluids as extractant, airtight, anaerobic, in the pressure vessel of low pressure, according to the similar principle mixed of organic matter, by extraction material and the molecular diffusion process of extractant in immersion process, the liposoluble constituent reached in solid material is transferred in liquid extractant, pass through the process of reduction vaporization again by extractant and object product separation, finally obtain object product, again squid protein juice is added enzymolysis and produce fish cream further, waste gas rationally processes, realize the production of integration, one-step method dewatering and defatting technique can be realized by this method and obtain fish oil simultaneously, fish cream, both the drawback of traditional process equipment had been overturned, the solid-liquid of equipment can be realized again, liquid liquid, the multifunctional usages such as multi-solvent.
2. fish oil fish cream production method according to claim 1, its feature: subcritical fluid extraction ultrasound assisted extraction, nontoxic, harmless, environmental protection, pollution-free, non-thermal technology, reservation extract biologically active prod do not destroy, are not oxidized, production capacity is large, can industrialization large-scale production, energy-conservation, operating cost is low, be easy to and product separation.
3. fish oil fish cream production method according to claim 1, its feature: the enzyme added is compound fertilizer production, joins in cooking reaction still and carries out enzymolysis.
