Retort
|
Retort pouches are made from a technologically advanced multi-layered film and aluminum material, filled with food, sealed, and heated for sterilizing purposes. It is this process that provides the durable quality, extended shelf life, and continued good flavour to every Meal Kit meal. Durable retort pouches can be air-dropped and subjected to field-handling.
Quality standards
Since the 1970s, retort pouches have been successfully used in MREs by the US DoD, FEMA, and the US Space Program. Meal Kit Supply Canada sourced these same agencies’ suppliers to ensure unmatched quality in all our products. Meal Kit retort pouches have passed rigorous testing at the manufacturer, the packager, and at Clemson University’s Department of Packaging Science.
Retort packaging advantages
Often referred-to as the flexible can, retort pouches have these advantages over cans:
- Lightweight – Reduces backpack weight and shipping charges.
- Compact – Requires less space than a can.
- Flexible – Fits easily into a backpack and is less prone to damage.
- Durable – Withstands extreme temperature changes and field-conditions handling.
- Easy-to-open – Notched package opens by hand. No can opener required.
- Freshness and taste retained – Offers an extended shelf-life and better taste than canned foods.
The retort process
Food is sealed in the triple-layer Meal Kit retort pouch and subjected to thermostabilization, a process much like canning. This ensures sterilization of the food inside, prevents future contamination for an extended shelf life, and locks-in the flavour and juices in the food.
The pouch consists of three layers fused together:
- Outer layer: A durable polyester film that provides protection for the food.
- Middle layer: Aluminum foil, which provides the moisture, oxygen, and light barrier properties to the pouch.
- Inner layer: An advanced polypropylene film that is compatible with a wide range of foods and offers an excellent heat seal.
