Present State and Prospect of Modified Atmosphere Packaging (MA) for Fresh Meat and Processed Meat Products

摘要

Modified Atmosphere Packaging (MAP) has become a widely used food preservation technique which minimally affects fresh product characteristics, and hence meet the needs of the recent consumers for fresh, natural and additive-free foods. The basic concepts of meat chemistry, meat microbiology and techniques for shelf life extension in MAP systems were reviewed. In MAP, the initial atmosphere surrounding a food is altered by the addition of CO_2 or a combination Of gases (O_2, N_2, and CO_2).
