example 1

[0188] Example 1. Simulate the current method of modified atmosphere used in the United States to keep 4×450g of beef fresh, check the quality of the beef after 21 days of storage and test the changes of oxygen and carbon dioxide concentrations with the storage days. The results are shown in Table 1. figure 1 shown

Abstract

An air-regulating antistaling agent for packed sliced meat relates to a meat air-regulating antistaling method and the antistaling agent used, belongs to the technical field of antistaling and sealing, and can be used in antistaling and sealing of meat and fish. The air-regulating agent comprises a low-temperature deoxygenation agent and / or gas mixture generator. Through chemical reaction, the optimum gas mixture required for antistaling of meat is automatically formed in a packaging bag so as to achieve the purposes of storing, antistaling and prolonging shelf life. In comparison with a present machinery air-regulating method, the invention has the following two big advantages: (1) the air-regulating agent provided by the invention has a function of automatically adjusting carbon dioxide concentration which always maintains the optimum stable state during the whole storage transportation period so as to effectively raise the antistaling quality and reliability of chilled meat, and the circumstance that the carbon dioxide concentration is sharply reduced with the storage time due to the loss of dissolved carbon dioxide in the present machinery air-regulating method will not occur; and (2) after the method provided by the invention is used, all the inflation processes are cancelled so as to save inflation package special-purpose production line, save manpower and resources by more than 90% and prolong the shelf life from 15-21d to more than 28d. The goals, which people have dreamed of for many years and strive for, are finally realized by the invention.

Description

technical field [0001] The modified atmosphere preservative for boxed cut meat (the boxed cut meat is a kind of cold fresh meat processed by the modified atmosphere packaging method in the warehouse of the external distribution center of the shopping mall) relates to a modified atmosphere preservation method for meat The used fresh-keeping agent belongs to the technical field of fresh-keeping and sealing, and can be used for fresh-keeping and sealing of meat and fish. Background technique [0002] In the 1980s, my country began to use the modified atmosphere method to preserve fresh fruits and vegetables. In 1988, the applicant invented "Double Suction Fresh-keeping Sealant and Its Preparation Method and Application" (ZL88105412.7) and the supporting product "Multi-dosage Anaerobic Indicator" (ZL91108195 .X) It has been successfully used in various food preservation such as moon cakes, oxtail, exported garlic, and high-moisture jujubes. After my country joined the WTO in 200...
