Abstract

A modified atmosphere fresh-keeping package for meat products is used for modified atmosphere fresh-keeping of cooked meat or fresh meat and comprises a package box body used for introducing modified atmosphere fresh-keeping gas, and a cover film; the packaging box body is provided with a first space and a second space; the cover film is used for sealing the packaging box body; the pressure intensity of the modified atmosphere fresh-keeping gas in the packaging box body is greater than the atmospheric pressure intensity; the first space is used for placing meat products; a compressed air bag is arranged in the second space and is fixed at the bottom of the second space; and the bottom or the side wall of the second space is provided with a size mark corresponding to the compressed air bag, and whether gas leakage exists in the modified atmosphere fresh-keeping package of the meat products or not can be judged according to the size mark of the compressed air bag.

Description

technical field [0001] The invention relates to the field of gas packaging with a classification number of B65D81 / 20, in particular to a modified atmosphere fresh-keeping packaging for meat products with a pressure greater than the standard pressure. Background technique [0002] There are three common processing methods in the Chinese market: frozen meat, hot fresh meat, and cold fresh meat. At present, the main fresh-keeping method for meat is freezing. Although frozen meat is very effective for prolonging the storage period of meat, when frozen meat is stored at -18°C, it will easily cause the loss of meat juice and nutrients when thawing, and the freshness and tenderness will decrease. There are disadvantages in maintaining the flavor. In addition, frozen storage is an energy-consuming process, which greatly increases the cost of meat in circulation. Hot fresh meat has higher temperature, poor sanitary conditions, poor flavor and taste, is prone to microbial contaminati...
