Description

A kind of partition processing method of full crabs serial products

Technical field:

The present invention relates to the partition processing method of a kind of crab meat deep working method and serial converted products, particularly a kind of full crabs serial products.

Background technology:

Fresh water crab fragrance delicious food, fine and tender taste not only is rich in protein, but also contains nutritions such as unrighted acid, lecithin, trace element and vitamin, always is the delicacies that has delicious and nutrition concurrently rare on people's dining table.Yet eating raw of crab is not only seasonal extremely strong, and the cooking and edible quite trouble.For the edible seasonality of crab that weakens, the researcher has been developed frozen crab, wine preserved crab, has been pickled the crab fabricated product that all can supply each season such as crab, the cooking and instant for people, the crab meat goods that instants such as exploitation crab meat, crab oil are also arranged, wherein especially with the elite of crab---crab oil (cream) be that the crab meat goods developed of primary raw material are the most representative.As application number be several patents such as 01127275.9,03132074.0,200410014605.2 and 200510039226.3 all disclose with crab oil and (or) crab meat is crab meat goods and the method for making thereof that raw material is made.Though these fabricated products all have the characteristics that all can supply each season with instant, but all lost the original shape of crab, still can not satisfy people to omnibearing higher pursuits such as crab meat goods color, shapes, also not consider simultaneously for zero of the edible part except that crab oil, crab leg in the full crab and abandon useless full-scale development utilization.

Summary of the invention:

Its purpose of the present invention is to provide a kind of original shape that can keep local crab body meat, can fully reclaim the partition processing method of abandoning the full crabs serial products of useless edible part in the division processing process simultaneously.

Its technical scheme is: a kind of partition processing method of full crabs serial products is characterized in that its method step:

The preliminary treatment of a, raw material crab:

The live body fresh water male and female crab of choosing gonad maturity and not having a deformity sent into respectively clean in the service sink that has oxygen increasing pump till the foreign material such as the no silt in crab surface;

B, boiling:

Public crab and the female crab cleaned are carried out boiling with steamer respectively, steam and begin to calculate digestion time after hot gas comes out: public crab 20～30 minutes, female crab 15～25 minutes;

C, cut apart extraction:

Extract the leg crab earlier with steaming good crab: the last leg of crab leg, middle leg, three positions of pincers are broken into two with one's hands with hand, cut off the leg two ends, cut off stupefied along both sides, break top lid into two with one's hands, respectively upward das Beinfleisch and middle das Beinfleisch of taking-up; Get rid of a mobilizable angle in the crab claw, iliacus is taken out of in the pincers, cut off the top at an angle of residue with scissors after, with the above-mentioned extracting method taking-up crab claw meat of going up das Beinfleisch and middle das Beinfleisch;

Again the crab limb is broken off with the fingers and thumb down from the crab body, cut off back two joints of crab limb, get last joint; Cut off along the both sides shell, break shell into two with one's hands, take out crab willow meat;

Steam box is put in the crab body sabot of breaking off with the fingers and thumb except that crab pin and crab limb, and boiling was taken out the back about 20 minutes again, opened the crab lid, the navel at the bottom of the removal taking-up crab abdomen and the cheek in the crab tripe; Scrape the crab cream on the public crab tripe, choose the black line in the crab cream, obtain crab cream; From the yellow female crab tripe of male and female crab lid neutralization, take out crab oil respectively, reject the black inner membrance on crab oil surface, obtain crab oil;

Crab limb root is outwards broken off with the fingers and thumb, divide upper and lower two-layer cut off the crab tripe after, the meat of choosing in the crab body is crab meat;

To cut apart and extract the crab meat leftover bits and pieces in irregular shape that produces in crab leg, crab limb and the crab body process and reclaim, and choose wherein foreign material such as broken shell, obtain the crab meat mincing.

D, with the above-mentioned last das Beinfleisch of extraction, middle das Beinfleisch, crab claw meat, crab willow meat, crab cream, crab oil, crab meat and the crab meat mincing cut apart, respectively through packing, promptly get on the crab das Beinfleisch goods, crab claw meat products, crab willow meat products, crab cream goods, crab oil goods, crab meat goods and crab comminuted meat product in das Beinfleisch goods, the crab after the sterilization.

Its technique effect is: outstanding feature of the present invention is each edible part of full crab has been carried out reasonable careful cutting apart, realized zero of crab edible part is abandoned useless comprehensive processing and utilization, and fully kept original shape of goods such as crab leg, the crab claw, satisfied people to omnibearing higher pursuits such as crab meat goods color, shapes.

The specific embodiment:

The preliminary treatment of a, raw material crab:
