Embodiment Construction

[0025] The invention provides a controlled atmosphere preservation method of Sujiang pork, which comprises the following steps: step 1, dividing the picked Sujiang pork with a sterilized knife, and the weight of each piece of Sujiang pork is 100g after cutting, and randomly divided into 4 groups, 8 packs in each group; step 2, prepare CO modified atmosphere group: press O 2 , CO 2 and CO for modified atmosphere preparation; CO modified atmosphere group, O 2 :CO 2 :CO=39.5:60:0.5, the O 2 , CO 2 and CO with a modified atmosphere packaging machine for modified atmosphere packaging, the inflation time of the inflatable packaging is 30s, and the inflation pressure is 0.2Pa; Step 3, the pork is subjected to modified atmosphere preservation: the cut pork is packaged in a CO modified atmosphere and placed in 0~ Refrigerate at 4°C.

[0026] The present invention further illustrates this preservation method by following experiment:

[0027] 1. Test method: Divide the harvested Su...

Abstract

The invention discloses a controlled atmosphere preserving method of Sujiang pork. The method comprises the following steps of step A. segmenting the purchased Sujiang pork through a sterilized cutter; step B. preparing a carbon oxide (CO) controlled atmosphere group: carrying out the controlled atmosphere preparation for oxygen (O2), carbon dioxide (CO2) and CO to prepare the CO controlled atmosphere group, wherein the ratio of O2 to CO2 to CO is 39.5 to 60 to 0.5; and step C. preserving the pork under the controlled atmosphere: packing the Sujiang pork under the controlled atmosphere of O2, CO2 and CO by utilizing a controlled atmosphere packing machine, wherein for the inflation packaging, the inflating time is 30s, and the inflation pressure is 0.2Pa; and carrying out cold storing on the segmented pork after being packed under the CO controlled atmosphere into a refrigerator at the temperature of 0 to 4 DEG C. The controlled atmosphere preserving method not only has a good preserving effect, but also has long preserving time.

Description

technical field [0001] The invention relates to a controlled-atmosphere preservation method for Sujiang pork, which belongs to the field of food preservation. Background technique [0002] Sujiang pig is a new breed of high-quality lean meat bred by Jiangsu Animal Husbandry and Veterinary Vocational and Technical College using local Jiangquhai pig as the female parent and introducing Duroc pig blood. This new breed has the advantages of high litter rate, good meat quality, and good taste of Jiangquhai pigs, as well as fast growth and high lean meat percentage of American Duroc pigs. But there is no report about the development and preservation of Sujiang pork products. At present, most consumers in our country are used to unpackaged or simply packaged pork. Consumers buy Sujiang pork fresh meat and eat it soon, or put it in the freezer of the refrigerator, but it can only be preserved for 2-3 days, the preservation time is relatively short, and the preservation effect is n...
