摘要: Improved processing and packaging for perishable goods such as red meats providing a system wherein ambient air is excluded suitable gases carbon dioxide are provided at pressure in manner to increase the quantity of dissolved goods. Then base placing over base. A flexible web plastic wrapping material (second web) then applied or gas evacuated therefrom replaced with gas. The includes cup-shaped tray recess (first web), plastics other material, side walls extending upwardly connect narrow horizontally disposed flange. first web, second located inside depression third barrier there together placed into an enclosed evacuation chamber. chamber displace substantially all particularly atmospheric oxygen that may be present materials. sealed so enclose webs. increased level above pressure. Most preferably will increased. introduced space enhance preservation when contacting thereby producing hermetically package filled contained therein provide package. can stored any convenient period time after which removed allow contact invention further method apparatus processed packaging.
