Further effort, led by Dr. Rauno A. Lampi, Chief of Food Systems Equipment Division at the Natick Soldier Research, Development and Engineering Center, concentrated on the refinement of the retort pouch to contain a wet ration with a three-to-ten year shelf life that could be easily shipped, carried in the field, opened and consumed straight ...
The main menu items of the IMP are "boil in a bag" (known as a "retort pouch") and require less preparation time and equipment than the previous canned rations. Another stated advantage is that preparation using retort pouches can be done using less heat, reducing the impact on the taste of the food. [2]
It was an 11-ounce (310 g) ration that came in a brown plastic retort pouch that allowed the user to reconstitute and cook the ration directly in the pouch. This was an improvement over the earlier LRP packet, which had to be boiled or soaked in a canteen cup or other cookware.
In a chemistry laboratory, a retort is a device used for distillation or dry distillation of substances. It consists of a spherical vessel with a long downward-pointing neck. The liquid to be distilled is placed in the vessel and heated.
Aseptic processing was derived from Olin Ball's heat-cool-fill (HCF) machine that was developed in 1927. [5] While HCF was successful in improving the sensory quality of the processed chocolate milk as compared to canned product, the use of the equipment was hindered by its cost, maintenance, and inflexibility to process various container sizes, rendering the machine a failure.
A stand-up pouch or doypack is a type of flexible packaging that is able to stand erect on its bottom for display, storage, and convenience.
