Problems solved by technology

[0003] Pork cold chain production is to divide pork into pork products, then freeze them for packaging and storage; when pork is processed in the cold chain, bacteria may be attached to the surface of pork, and some bacteria with strong tolerance may be in the pork. Breeding on it may spoil the pork

Embodiment 1

[0020] A kind of pork cold chain production technique, described production technique comprises the steps:

[0021] (1) Segmentation of pork: Segment the pigs after slaughter, so that the pork is divided into: meat products, bone products, by-products and refined products according to the processing parts. The temperature of the segmentation workshop is controlled between 12 and 15°C , the tools for pork segmentation need to be cleaned and sterilized three times a day;

[0022] (2) Pre-cooling treatment. After the pork is cut and processed, the cooling workshop is pulled down, and the temperature is gradually lowered and cooled through three different temperatures of 10°C, 5°C and 0°C. Finally, the central temperature of the pork product is not higher than 7°C. The cooling time of the temperature stage is controlled at 1h, 1.6h and 14h respectively. During the pre-cooling process of pork products, ultraviolet germicidal lamps are used for auxiliary sterilization, and the ultra...

Embodiment 2

[0033] A kind of pork cold chain production technique, described production technique comprises the steps:

[0034] (1) Segmentation of pork: Segment the pigs after slaughter, so that the pork is divided into: meat products, bone products, by-products and refined products according to the processing parts. The temperature of the segmentation workshop is controlled between 12 and 15°C , the tools for pork segmentation need to be cleaned and sterilized three times a day;

[0035] (2) Pre-cooling treatment. After the pork is cut and processed, the cooling workshop is pulled down, and the temperature is gradually lowered and cooled through three different temperatures of 15°C, 10°C and 4°C. Finally, the center temperature of the pork product is not higher than 7°C. The cooling time of the temperature stage is controlled at 1.6h, 2.2h and 16h respectively. During the pre-cooling process of pork products, ultraviolet germicidal lamps are used for auxiliary sterilization, and the ult...

Abstract

The invention discloses a cold-chain production technology for pork. The production technology comprises the following steps of pork cutting, wherein a slaughtered pig is cut; pre-cooling, wherein after being cut, the pork is transported to a cooling workshop and subjected to step-by-step cooling at different temperatures of 15-10 DEG C, 10-5 DEG C and 4-0 DEG C, and finally, the center temperature of the pork product is not higher than 7 DEG C; freezing treatment, wherein the pork product obtained after sufficient pre-cooling is frozen, so that the pork center temperature reaches -18 DEG C orbelow; packaging, wherein after freezing treatment, the pork is packaged with a plastic thin film, then transported into a refrigerated warehouse of the temperature of -18 DEG C and refrigerated. Thecold-chain production technology has the advantages that when the pork is pre-cooled, the surface of the pork can be sterilized, the bacteria content can be reduced, and storage of the pork is prevented from being affected; the pork is pre-cooled in three stages to discharge acid, the acid discharging effect is good, and the taste of the pork is improved.

Description

technical field [0001] The invention relates to a cold chain production process, in particular to a pork cold chain production process, and belongs to the technical field of pork cold chain production process application. Background technique [0002] Meat cold chain refers to keeping meat at 0-4°C refrigerating conditions or -20--30°C freezing conditions during meat slaughtering, segmentation, processing, packaging, storage, transportation, sales, and final consumption. ; Required, including workshop cooling, refrigerated room storage, refrigerated truck transportation, wholesale or retail and other intermediate turnover cold storage or freezer temporary storage, and family refrigerator storage and other full-process temperature control systems. [0003] Pork cold chain production is to divide pork into pork products, then freeze them for packaging and storage; when pork is processed in the cold chain, bacteria may be attached to the surface of pork, and some bacteria with ...
