Description
Technical Field
The invention relates to the field of gas packaging with classification number B65D81/20, in particular to a modified atmosphere packaging for meat products with pressure greater than standard air pressure.
Background
The common processing methods in the market of China are three types: frozen meat, hot fresh meat, cold fresh meat. At present, the main fresh-keeping mode of meat is freezing fresh-keeping, although the freezing meat is very effective for prolonging the storage period of the meat, the freezing meat is stored at the temperature of minus 18 ℃, the meat juice and nutrition are easily lost when the freezing meat is thawed, the freshness and the tenderness are reduced, and the defect of flavor maintenance exists. The hot fresh meat has high temperature, poor sanitary condition, poor flavor and taste, easy microbial pollution and short shelf life. The cold fresh meat is based on a perfect cold chain system, has the characteristics of nutrition, delicacy, safety and the like by taking good operation specifications as a guarantee, is developed into a main meat processing method, and has considerable development prospect.
At present, for the preservation of meat, in addition to the traditional refrigeration and frozen preservation, the ice temperature preservation technology and the controlled atmosphere preservation technology are also gradually popular. The ice temperature technology is a brand-new storage and preservation technology, overcomes various defects of cold storage and frozen storage, and can well ensure the flavor, taste and freshness of food. The modified atmosphere preservation technology is based on cold preservation, and is characterized by increasing gas component regulation, inhibiting microbial respiration, delaying the metabolic process and better keeping food freshness and commodity. The fresh-keeping mechanism of fresh meat modified atmosphere package is that according to the characteristics of different fresh meat and their respective fresh-keeping requirements, the package bag is vacuumized, then the mixed gas with a certain quantity of proportion is filled in the package bag, so that the gas environment for storing fresh meat can be actively regulated, and the condition for living and breeding of microbe can be damaged or changed, so that the physiological and biochemical deterioration of packaged food can be retarded, and the goal of antisepsis and fresh-keeping can be reached.
In the prior art, patents CN104369981A, CN103693295A, CN109353699A, CN102464112A and the like respectively disclose modified atmosphere packaging for food, which is different from vacuum packaging, in that if the packaging is not qualified or the packaging is communicated with outside air due to improper transportation, the vacuum packaging can be judged by observing whether the package surface is expanded, and the modified atmosphere packaging is filled with gas, so that the packaging condition cannot be determined by appearance when the packaging is leaked, which may cause consumers to eat deteriorated meat products and affect the product quality.

Further, the pressure intensity of the atmosphere-controlled fresh-keeping gas in the packaging box body is 1.1-1.2 times of atmospheric pressure.
Further, the cover film is made of a high-barrier material with a low oxygen permeability coefficient.
Further, the compressed air bag size mark comprises a first mark and a second mark, the first mark corresponds to the size of the modified atmosphere gas pressure of the compressed air bag in the packaging box, and the second mark corresponds to the size of the compressed air bag under the atmospheric pressure.
Further, when the size of the compression air bag is the first mark, the packaging box body is determined not to leak; and when the size of the compression air bag is the second mark, determining that the packaging box body has leakage.
Further, the first space and the second space are separated by a partition.
Further, the partition part is a mesh or a partition plate.
Further, the first space is in gas communication with the second space.
Further, the meat product is a fresh meat product or a cooked meat product.
Further, the meat product is pork, beef, mutton or poultry.
Further, the compression balloon is made of latex or rubber material.
Furthermore, the compressed air bag is filled with the modified atmosphere fresh-keeping gas which is the same as the packaging box body.
Further, the modified atmosphere fresh-keeping gas is nitrogen or a mixed gas of nitrogen and carbon dioxide.
Further, the content of carbon dioxide in the mixed gas is 20% -60%.
Detailed Description
The following embodiments of the present invention will be described in detail with reference to the accompanying examples, so that how to apply the technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented. It should be noted that, as long as there is no conflict, the embodiments and the features of the embodiments of the present invention may be combined with each other, and the technical solutions formed are within the scope of the present invention.
The invention relates to a modified atmosphere packaging for meat products, which comprises: and the packaging box body is provided with a cover film for sealing the packaging box body. The packaging box body can be a cube or a cuboid or a cylinder. The cover film is made of high-barrier material with low oxygen permeability coefficient, and the same material as the packaging box body, such as composite PE film, composite PP film or PVDC film, can be used as the cover film of the packaging box body.
The packaging box body is used for introducing modified atmosphere fresh-keeping gas, and nitrogen, or mixed gas of nitrogen and carbon dioxide, or mixed gas of nitrogen, carbon dioxide and oxygen can be used as the modified atmosphere fresh-keeping gas. When the mixed gas is used, the content of carbon dioxide is 20% -60%, and the content of oxygen is less than 10%. The pressure of the atmosphere-controlled fresh-keeping gas in the packaging box body is greater than the atmospheric pressure, and the atmospheric pressure of the atmosphere-controlled fresh-keeping gas in the packaging box body can be set to be 1.1-1.2 times.
