Abstract
The invention relates to a gas cooking processing method for crabs, which comprises the following steps: putting the fished fresh crabs into the boiled, cooled and oxygenated low-temperature seawater to be temporarily cultured for 18 to 36 hours, then taking the crabs out, dewatering the crabs, removing spikes and burrs on the crab bodies, fixing crab pincers, crab legs and crab bodies by adopting edible bundles, then curing the pretreated crabs, nitrogen gas packing, sterilizing and cooling the crabs, and placing the crabs in a refrigeration storage to be preserved. The method has simple and convenient process and feasible operation; the processed crab food is convenient to eat, and has fresh taste and good mouthfeel; the bacteria are thoroughly killed; the shelf life is obviously prolonged and the individual is kept complete by nitrogen gas packing; and generally, the crab food can be preserved for 6 months at the temperature of between 3 and 5 DEG C.
Description
Technical field
The present invention relates to a kind of shell-fish aquatic food goods, the gas-containing cooking processing method of especially a kind of crab.
Background technology
The crab delicious flavour, nutritious, amino acid is formed comprehensively, and inorganic salts such as calcium, iron, iodine, copper, potassium and vitamin content are abundant.Protein content is 14% in the crab, and fatty 2.6%-5.9% is based on unrighted acid.In addition, crab also has good medical value.The traditional Chinese medical science is thought: crab is cold in nature, and it is salty to distinguish the flavor of, and goes into liver stomach two warps, and promoting blood circulation and stopping pain is arranged, and the function of eliminating inflammation and expelling toxin can be used for treating traumatic injury, disease such as warm.
Traditional eating method of crab is now to catch the usefulness of now cooking, because crab edible has stronger seasonality, generally reaches the most fertile phase 8-10 month crab, misses the crab that catches season and obviously becomes thin, and has a nasty taste.In addition, the crab body contains more histidine, and histidine easily decomposes, and can produce histamine and class group ammoniacal substance under the effect of decarboxylase, especially works as crab after death, and histidine decomposes rapider.Therefore, after the crab shortening under the normal temperature normality utmost point cannot say for sure to deposit, the time is long slightly, not only the delicate flavour of crab is all gone, even can rot and bring harm to people healthy.At present, the deep process technology of crab has been carried out exploitation energetically, a lot of people attempt to adopting after the binding of whole crab employing rubber muscle, the slaking vacuum-packed, to prolong its shelf-life.But because thorniness on the housing of crab, vacuumize packing and the time very easily puncture packaging bag, and influence the shelf-life, and vacuumize and also easily cause flat flat distortion of crab body or the fragmentation of crab shell, therefore, adopt vacuum-packed mode to be difficult to keep the original shape of crab and the genuineness of taste.How whole crab is processed, preserves, become the technical problem that crab processing needs to be resolved hurrily with the delicate flavour that is convenient for people to enjoy throughout the year crab.In addition, putrescibility materials such as crab happiness food spoil, thus normal band malignant bacteria in its stomach and intestine, therefore, and in the process of crab, the going out except that being a very important problem also of bacterium.
Summary of the invention
Carry out vacuum-packedly easily causing thorn on the flat flat distortion of crab body or fragmentation of crab shell and the housing thereof easily to puncture packaging bag and influencing the deficiency of shelf-life in order to overcome in the prior art whole crab to slaking, the invention provides the gas-containing cooking processing method of a kind of crab.This processing method technology is easy, operation feasible, and the crab food body after the processing is complete, and long shelf-life is safe, instant.
The technical solution adopted for the present invention to solve the technical problems is: the gas-containing cooking processing method of a kind of crab, it is characterized in that: the fresh crab after will fishing for put into through boil, low temperature seawater after the cooling, oxygenation supported 18-36 hour temporarily, take out, draining behind the spine on the removal crab health, the burr, adopts edible harness thing that its crab claw, crab leg and crab body are fixed, then above-mentioned pretreated crab is carried out slaking, nitrogen-filled packaging, sterilization is inserted in the freezer after the cooling and is preserved.
Above-mentioned low temperature seawater of supporting crab temporarily, its temperature is 3-6 ℃.
The fixing edible harness thing of the above-mentioned crab claw with crab, crab leg and crab body is the cucurbit strand.
Above-mentioned slaking that pretreated crab is carried out is that pretreated crab is inserted in the pot, feeds vapours, and the control temperature is steamed 20min between 95-100 ℃.
The above-mentioned cooked crab with nitrogen-filled packaging carries out sterilization, cooling is the mode that adopts multistage intensification sterilization, cools off fast, be that 80 ℃ of temperature keep 10-15min, are warming up to 100 ℃ of maintenance 10-15min, are warming up to 121 ℃ of maintenance 10-15min, cooling fast then.
Above-mentioned with nitrogen-filled packaging, sterilization, cooled crab is inserted in the freezer and preserves, and the temperature of its freezer is controlled at 3-6 ℃.
The present invention goes into to boil, supports temporarily in the low temperature seawater after the cooling, oxygenation fresh crab, to stimulate its spue sewage and impurity, goes out except that the part malignant bacteria in the stomach and intestine, and can make its action become slow, is beneficial to follow-up deburring, harness processing; Behind spine on the removal crab health, the burr, can prevent effectively that the spine on the housing from puncturing packaging bag, guarantee its shelf-life; Adopt edible harness thing cucurbit strand that the crab claw, crab leg and crab body are fixed, fully kept the build of crab complete, and can prevent that tradition from adopting the rubber muscle to tie up the peculiar smell that is brought; Adopt the steam cure crab, purpose is in order to reduce the especially breeding of vibrios of microorganism in the crab, to carry out the bacteria reducing processing, reducing the used time of follow-up sterilization; Nitrogen is as a kind of asphyxiating inert gas, bacterium in food procreation had suffocate and inhibitory action, and be not easy to see through packaging film, therefore nitrogen-filled packaging mouthfeel, taste and the nutrition that can keep food preferably, prolong its shelf-life, and nitrogen-filled packaging also can play the good protection effect for the crab shape in the bag, prevents to be squeezed in the transportation broken; Adopt multistage intensification sterilization, Cooling Mode can guarantee the toughness mouthfeel of crab meat to greatest extent, and thorough kill bacteria, prevent the decomposition of its histidine, fully guarantee the nothing loss of crab delicate flavour, reach the mouthfeel the same with the edible fresh crab.
Technology of the present invention is easy, operation feasible, and the crab food consumption after the processing is convenient, delicious flavour, the shelf-life obviously prolongs, and can preserve 6 months under general 3-5 ℃ of condition.
