Abstract
The invention discloses a process for refrigerating and packaging pork. The method comprises the following specific steps of quantitatively grading and packaging segmented pork blocks, and freezing the pork blocks before the refrigeration, wherein the freezing way is rapid freezing way. A packaging bag for grading packaging the pork blocks is required not to split and strip under the temperature being minus 20 DEG C, the rapid freezing condition is that the temperature is less than minus 29 DEG C, the cooling time is controlled to be 26 to 28h, and the temperature of the rapidly-frozen pork block is lower than minus 16 DEG C. By adopting the rapid freezing manner, nutrients of the pork are free from being lost, then the pork is refrigerated, the shelf period of the pork can be prolonged, the freezing condition is controlled, so that the temperature of the frozen pork is lower than minus 16DEG C and similar to a refrigeration chamber, and convenience in long-term storage can be realized. In addition, in order to further guarantee the freshness of the long-term stored pork, the temperature range of the refrigeration chamber is strictly controlled, the influence on the pork caused by the temperature difference can be reduced, the obtained pork blocks can be stored for a long time without going bad, and the requirement of consumers can be met.
Description
Technical field
The present invention relates to finished product pork pies to fill and refrigerate the technical field of depositing, relate in particular to the technique of pork refrigeration package.
Background technology
The product that refrigeration is distributed and stored for needs is as pork, and the Pork-pieces being split to form after live pig is slaughtered, all needs to carry out refrigeration package during sale, to extend the shelf-life of pork, so the pork that people buy on market major part is chilled meat.The operation pot-lives different from condition that pork after packing refrigerates also can change, the time that the producer that pork is sold all wishes pork cold storing and fresh-keeping, the longer the better, but, the shelf-life of common refrigeration package pork only has four or five months, and the time that how to extend pork fresh-keeping and cold storage becomes the in the urgent need to address and technical problem of failing of those skilled in the art.
Summary of the invention
In view of this, the invention provides a kind of technique of pork refrigeration package, pork is carried out to quantitative classification packing, before refrigeration, freeze, make the pork shelf-life extend to 11 months.
For solving the problems of the technologies described above, the invention provides a kind of technique of pork refrigeration package, the Pork-pieces after cutting apart is carried out to quantitative classification packing, before refrigeration, to freeze, the mode of freezing is quick freezing.
Preferably, the packaging bag for minute grade packaged Pork-pieces requires not split bag and not delamination at-20 ℃.Because freeze, so in order to guarantee that the quality packaging bag of pork must have stronger freezing tolerance, there will not be any opening under cryogenic conditions.
Preferably, described quick freezing condition is that below temperature-29 ℃, temperature fall time is controlled at 26-28h.
Preferably, after described quick freezing the temperature of Pork-pieces lower than-16 ℃.
Preferably, put into refrigerating chamber stored refrigerated for the Pork-pieces after freezing, the shelf-life is 11 months.
Preferably, the temperature of described refrigerating chamber should be controlled at-18 ℃ to-17 ℃, and humidity is controlled at more than 98%.Only have strict control temperature, make temperature wave moment not surpass 1 ℃, just do not affect the preservation of meat.During Cold Storage can be regularly to the refrigerating chamber sterilization that carries out disinfection, prevent that bacterium infected pigs meat cited from playing qualitative change.
Compared with prior art, tool of the present invention has the following advantages:
The present invention adopts quick freezing that the nutrition of pork can not lost, and then carries out stored refrigeratedly, extends shelf-life of pork, the condition of control freezing, make the temperature of pork after freezing lower than subzero 16 degree, close with the temperature of refrigerating chamber, just can preserve for a long time.In addition, applicant, in order further to ensure the fresh of long term storage pork, strictly controls the temperature range of refrigerating chamber, reduces the impact of the temperature difference on pork, and the long-term preservation of Pork-pieces obtaining also undergoes no deterioration, and can satisfy the demands of consumers.
The specific embodiment
In order to make those skilled in the art understand better technical scheme of the present invention, below in conjunction with specific embodiment, the present invention is described in further detail.
Below in conjunction with embodiment, the specific embodiment of the present invention is further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
A technique for pork refrigeration package, concrete operations are:
Pork-pieces after cutting apart is carried out to quantitative classification packing, before refrigeration, freeze, the mode of freezing is quick freezing.Packaging bag for minute grade packaged Pork-pieces requires not split bag and not delamination at-20 ℃.Because freeze, so in order to guarantee that the quality packaging bag of pork must have stronger freezing tolerance, there will not be any opening under cryogenic conditions.
Quick freezing condition is that below temperature-29 ℃, temperature fall time is controlled at 26-28h.After quick freezing, the temperature of Pork-pieces is lower than-16 ℃.
For the Pork-pieces after freezing, put into refrigerating chamber stored refrigerated, the shelf-life is 11 months.The temperature of refrigerating chamber should be controlled at-18 ℃ to-17 ℃, and humidity is controlled at more than 98%.Only have strict control temperature, make temperature wave moment not surpass 1 ℃, just do not affect the preservation of meat.During Cold Storage can be regularly to the refrigerating chamber sterilization that carries out disinfection, prevent that bacterium infected pigs meat cited from playing qualitative change.
Quick freezing can not lost the nutrition of pork, and then carries out stored refrigeratedly, extends shelf-life of pork, and the condition of control freezing, makes the temperature of pork after freezing lower than subzero 16 degree, close with the temperature of refrigerating chamber, just can preserve for a long time.In addition, applicant, in order further to ensure the fresh of long term storage pork, strictly controls the temperature range of refrigerating chamber, reduces the impact of the temperature difference on pork, and the long-term preservation of Pork-pieces obtaining also undergoes no deterioration, and can satisfy the demands of consumers.
Below be only the preferred embodiment of the present invention, it should be pointed out that above-mentioned preferred embodiment should not be considered as limitation of the present invention, protection scope of the present invention should be as the criterion with claim limited range.For those skilled in the art, without departing from the spirit and scope of the present invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
