Abstract

The present invention relates to fish processing method, and is process of preparing fine fish powder and superfine fish powder and extracting medicine component from fish. Under low temperature, fish is crushed and dried to obtain basic fish powder. The basic fish powder is further airflow crushed to obtain superfine fish powder, and the superfine fish powder is supercritical CO2 extracted to obtain medicine component. The present invention has whole fish processed to obtain fine fish powder and superfine fish powder and can maintain all the effective components and nutritive components of fish. The supercritical CO2 extraction process with cell wall crushing powder as material can obtain the medicinal effective component with no contamination, purity over 99 % and extraction rate over 98 %.

Description

The processing method of a kind of fish

One, technical field

The present invention relates to the processing method of a kind of fish, particularly relate to the method for from fish, producing fine powder, micropowders and extracting pharmaceutical compositions.

Two, background technology

Make at present fine powder and extract the method for pharmaceutical compositions from aquatic products, at first fish is slaughtered, abandon squama, bone, internal organs, then, 1. the water concentrate drying of heating is made fine powder; 2. pulverize with oven dry and room temperature and make fine powder.The major defect of above-mentioned preparation method: 1. the utilization rate of fish is low, only utilize the part material of fish, has abandoned part useful in the fish to some extent; 2. heating is lost a lot of active ingredients, nutrition and trace element in the fish for a long time.

Three, summary of the invention

The object of the present invention is to provide a kind of method of from whole fish, producing trickle, micropowders and extracting pharmaceutical compositions.

Technical scheme of the present invention realizes by following scheme: complete full fish, comprise head, tail, squama, bone, the gill, internal organs and blood, carrying out clear water handles, towards the nitrogen water treatment, under-19 ℃～-40 ℃ cryogenic conditions, carry out pulverize at low temperature and cold drying then, 100 orders～600 purpose fish flour base materials have been obtained, the fish flour base material is carried out the collision type comminution by gas stream, obtain the micropowders raw material of 1250 orders～12500 order fishes, the micropowders raw material of fish is extracted medicinal component in the fish by the carbon dioxide supercritical fluid extraction method, obtain carrying out microwave sterilizating after the product encapsulation and handle.

With described fish flour base material, the fish flour base material of one or more fishes adds 1.5% (weight) tea polyphenols antioxidant, is mixed at homogenizer, obtains carrying out microwave treatment after the product encapsulation.

Advantage of the present invention 1. can obtain fine powder and micropowders to greatest extent from fish integral body, the raw material availability height, and the yield height reduces cost greatly; 2. whole process is taked machining at low temperature technology, has kept whole active ingredients and the nutrition of fish; 3. all take machining at low temperature technology sterilization effect outstanding, carry out the microwave penetration sterilization treatment again after the product encapsulation in addition, it is more thorough to sterilize; 4. owing to added the natural tea polyphenol antioxidant in even matter technical process, make product fresh-keeping, remove smell as of rotten fish, pollution-free; 5. improved deep processing ability, used the breaking cell wall powder, just the micropowders of 1250～12500 order fishes fish, by the carbon dioxide supercritical fluid extraction method, can from fish, extract pollution-free, purity＞99%, extraction ratio＞98%, the active ingredient that medical value is high.

Four, the specific embodiment

Embodiments of the invention are below described:

Example 1,2000 gram Monopteri albis and Misgurni anguillicaudatis are put into clear water reserviors respectively supported 2～3 days, change over to respectively then in another clear water reserviors towards nitrogen precooled and sterilization; Respectively they are sent into the low temperature chamber pulverizing at ultralow temperature again, temperature is controlled at and is lower than-19 ℃, and the granule that crushes is carried out classification, control D ₉₇〉=300 orders carry out low temperature, vacuum drying at last, and temperature is controlled at and is lower than-30 ℃, obtain 300 orders, 500 gram Monopteri albi powder and 300 orders, 440 gram Misgurni anguillicaudati powder.With dried Monopterus albus (Zuiew) powder and dried Misgurni anguillicaudati powder respectively with 1.5% (weight) tea rich in selenium polyphenol (Se content 0.068mg/kg, polyphenol content 〉=98%) handled several minutes with homogenizer, disinfect with microwave penetration the encapsulation back, just obtains rich selenium Monopteri albi powder and rich selenium Misgurni anguillicaudati powder functional food ingredient and two kinds of products of health care medical industry base material.

Example 2, the rich selenium Monopteri albi powder that obtains in " example 1 " and each 250 gram of rich selenium Misgurni anguillicaudati powder are put into the homogenizing blender handled 20 minutes, will spare then during two kind of 300 order fen-ting amount that matter handles well incapsulate, just obtain " rich selenium loach eel capsules " health care medicine.

Example 3,2000 gram Ctenopharyngodon idellus full fishes are obtained D by same technology in " example 1 " ₉₇The Ctenopharyngodon idellus fish flour of 〉=200 orders 420 gram (removing＞78.6% water content), with 200 order Ctenopharyngodon idellus fish flour in the collision type jet mill crushing and classification to broken cell level granularity, D ₉₇〉=1250 orders.Ultramicrofine Ctenopharyngodon idellus powder with 420 gram breaking cell wall levels, put into supercritical extraction reactor through carbon dioxide abstraction, keep extraction kettle internal pressure 30～31Mpa, 70～80 ℃ of temperature, extracted 25 minutes, the reuse chromatography obtains purity＞98%, and the polyene unsaturated fatty acid of extraction rate reached 95～99% (DHA, EPA) has obtained cardiovascular and cerebrovascular disease is had the medical industry base material of unique curative effect.

Claims

1. the processing method of a fish, it is characterized in that complete full fish, comprise head, tail, squama, bone, the gill, internal organs and blood, carrying out clear water handles, towards the nitrogen water treatment, under-19 ℃～-40 ℃ cryogenic conditions, carry out pulverize at low temperature and cold drying then, 100 orders～600 purpose fish flour base materials have been obtained, the fish flour base material is carried out the collision type comminution by gas stream, obtain the micropowders raw material of 1250 orders～12500 order fishes, the micropowders raw material of fish is extracted medicinal component in the fish by the carbon dioxide supercritical fluid extraction method, obtain carrying out microwave sterilizating after the product encapsulation and handle.
