SECTION I - MRE HISTORY
-----------------------

MREs (Meals Ready to Eat) were born on Earth, but grew up on Apollo flights 
to the moon, in Skylab floating workshops and on every U.S. Space Shuttle 
flight from Enterprise to Atlantis.

In the 1970s retort pouches (the popular name for thermostabilized, 
laminated food pouches named after the retort cooker ) were put to their 
first real test by the U.S. Space Program. The Program was looking for 
delicious, easy to prepare, "normal" food that wouldn't increase human 
stress the way that freeze dried food and "toothpaste tube food" did. 
More than any other technology, retort pouches have satisfied the Program's 
needs. And so, over 20 years ago, retort pouches found a home at NASA, 
where all their unusual characteristics were much appreciated and they have 
been successfully feeding astronauts in flight and on the moon ever since.


THE HISTORY OF THE MRE

In the 1980s the U.S. military research labs, which had hatched the pouch 
technology in the first place, took the lead in its use and development. 
They enabled the U.S. Military to upgrade its entire field ration program
to retort pouches, from the earlier, less workable technologies of canning 
and freeze drying. Over the past 10 years these high tech research labs 
have continually upgraded the taste and nutritional profile of the meals.

Over the past 10 years our military has depended on MREs for its field 
ration requirements. Tens of millions of MRE "full meals"  have been 
produced and eaten. They have gone to Grenada, to the war on drugs, to 
fight forest fires in Alaska, and to feed the troops in  "Desert Shield" 
and Desert Storm.
 

SECTION II - POUCH CONSTRUCTION
--------------------------------

The big breakthrough was the pouch. Its three special layers allow the food 
to be sealed and then cooked (opposite from other food processing methods)
and never exposed to the air again until opened. Thus, the food is actually 
sterilized In the pouch and then blocked from future contamination. The 
result is the almost unbelievable shelf life and food which retains its 
natural moisture and juice (i.e. it is not freeze dried or dehydrated).

Here Is the breakdown of the breakthrough pouch:

     OUTERLAYER: A tough polyester film which provides protection for the 
		 middle layer and Is an excellent printing surface.

     MIDDLE LAYER: The key to the pouch's shelf stability, aluminum foil, 
		   the most effective and economical barrier to moisture, 
		   light and oxygen. The result: No refrigeration or 
		   freezing will ever be required.

     INNER LAYER: Next to the food product is a very special polypropylene 
		  film. It Is compatible with the widest variety of foods 
		  so that no "canned" or other unwanted taste is added to 
		  the food. It also ensures an exceptionally strong heat seal.



SECTION III - SHELF LIFE AND STORAGE/TEMPERATURE CHART

MRE SHELF LIFE

A main concern in the development and testing of rations for our armed 
forces has always been shelf life. An amazing amount of research has been 
done in the development of the retort pouch and the MRE to determine the 
exact length of time and the exact conditions under which it is safe to 
store the entrees and side dishes.

The main thing we have to work with is the shelf life chart (shown below) 
compiled by the Army's Natick Research labs. This gives a very good 
overview and summary of all the findings gathered from all the testing of 
MRE products. However, it leaves many questions unanswered. Here are 
additional facts and observations that have been gathered about MRE shelf life:

 1) The Shelf life ratings shown in the chart above were determined by 
    taste panels, panels of "average" people, mostly office personnel at 
    the Natick labs. Their opinions were combined to determine when a 
    particular component or, in this case, the entire MRE ration, was no 
    longer acceptable.

 2) The Shelf life determinations were made solely on the basis of taste, 
    as it was discovered that acceptable nutritional content and basic 
    product safety would extend way beyond the point where taste degradation 
    would occur. This means that the MRE would be safe and give a high 
    degree of food value long after the official expiration of the products 
    as determined by taste.

  3) MRE pouches have been tested and redesigned where necessary according to
     standards much more strict than for commercial food. They must be
     able to stand up to abuse tests such as obstacle course traversals in
     field clothing pockets, storage outdoors anywhere in the world, shipping
     under extremely rough circumstances (such as by half track over rocky
     terrain), 100% survival of parachute drops, 75% survival of free-fall
     air drops, severe repetitive vibration (1 hour at 1 G vibration),
     7,920 individual pouch drops from 20 inches, and individual pouches
     being subjected to a static load of 200 lbs for 3 minutes.

  4) Freezing an MRE retort pouch does not destroy the food inside, but 
     repeated freezing increases the chances that the stretching and 
     stressing of the pouch will cause a break in a layer of the laminated 
     pouch. These pouches are made to withstand 1,000 flexes, but repetitive 
     freezing does increase the failure rate by a small fraction of a percent.

BELOW 60 degrees Not enough data yet collected. However, projections are 
that the 130 months will be surpassed.

This chart contains storage life projections for MRE rations from the U.S. 
Army's Natick Research Laboratories and does not reflect a manufacturer's 
or vendor's guarantee.


NOTE: Time and temperature have a cumulative effect. For example, storage at
100 degrees for 11 months moved to 70 degrees would lose one half of the 70 
degree storage.
