Processing Methods

All processing methods outlined below act to extend food shelf life

Vacuum Pack

Vacuum-packing is probably the most economical means of extending shelf life. The processing technique reduces oxygen (O₂) levels as much as possible via extreme vacuum. The pre-formed pouch or automated packaging must have a good barrier to prevent O₂ re-entering the pack. When food products like bone-in meat is vacuum-packed, a high puncture resistance pouch may be required.

Modified Atmosphere Packaging (MAP)/Gas Flush

Modified Atmosphere Packaging changes the ambient atmosphere in packaging to prevent bacteria growth rather than using thermal processes to extend shelf life. Modified atmosphere packaging is gas flushed, replacing air with nitrogen or a nitrogen/oxygen mix. This inhibits spoilage and prevents the growth of bacteria that adversely affect food colour and taste. This technique is used on a variety of perishable foods, including meats, seafood, prepared foods, cheeses and other dairy products. Key benefits are a longer shelf life and a fresher taste.

Hot fill/Cook-Chill

Hot fill involves fully cooking the product, filling into a pouch (typically) at temperatures in excess of 85°C followed by rapid chilling and storage at 0-4°C.

Pasteurisation

This process occurs after food is packed. The pack is then heated to a temperature in excess of 100°C. Pasteurisation will normally achieve a longer shelf life than hot fill.

Retort

Retort flexible packaging is a food processing method that uses steam or superheated water to heat product to temperatures typically in excess of 121°C or 135°C in a retort chamber. This sterilizes the product after food is packaged. Retorting is a technique that can achieve a shelf life of up to 12 months at ambient temperatures. Extra high barrier packaging is required for this process < 1 cc/m2/24 hrs.

Microwavable Retort Pouch contains a special ALOx polyester film, which has a comparable barrier property to that of the aluminum layer.
