These factors include efficiency of vacuum, permeability of packaging materials to O2, and the
composition of gas (in the gas-flushing method) used.2-6 High vacuum can effectively control the growth of aerobes by removing O2 from the products, except probably trapped and dissolved O2 Similarly, packaging films that prevent or considerably reduce permeation of O2 during storage effectively control the growth of aerobes. Minute leaks in the film can adversely affect the protective effect of vacuum packaging or gas-flush packaging. The development of polymeric film has helped greatly reduce the O2 permeability. In gas flushing, CO2 and N2, and in the case of fresh meat along with some 02, are used in a mixture. N2 is used as inert filter and O2 is used to give the red oxymyoglobin color of meat. CO2 is used for its antimicrobial effect. As low as 20% CO2 has been found to control growth of aerobes, such as Pseudomomas, Acinetobacter, and Morexella; however, in general, C02 at 40-60% give better results. In some cases. 100% CO2 is used
