Retort Canning, Basic Information

Retort Canning
Retort canning is a widely used, safe way of commercial canning foods, typically for retail use. Retort pouch bags are used for canning, a process fast becoming an industry standard for commercial food preparations.
Retort pouches have often been used in field rations, space food and camping foods. A retort pouch is made of multiple layers of flexible laminate. If you’ve seen a Capri Sun juice pouch, you’ve seen an example of a retort pouch. You may have also seen tuna companies, such as StarKist or Chicken of the Sea utilizing the retort pouch sealing method. The metal foil laminate is gaining popularity in use as an alternative to traditional canning methods.
The U.S. Army, Reynolds Metals Company and Continental Flexible packaging originally invented the pouch. Historically, the U.S. military has used the pouches for field rations (MREs or Meals, Ready-to-Eat).
The flexible metal-plastic laminate is able to withstand thermal processing used for sterilization, which makes for a safe food storage environment. The pouch is heated under high temperature for several minutes, under high pressure inside retort machines. Food inside the pouches is cooked, in a way similar to pressure-cooking. This sterilization process kills all common microorganisms and prevents food from spoiling.
The retort canning process is similar to canning, with the exception of the container being flexible. The pouches are not regular Mylar bags. Retort canning uses pouches that have been specifically designed to withstand being hot packed.
Many foods lend themselves to the flexibility of the retort canning method, so today’s canners are moving toward this increasingly popular style of canning.

I love both capri suns and starkist in pouches and have never worried about safety so I guess its a good way to can. Never heard about leaking or problems with stuff getting into them. If the military trusts this type of canning I believe I can to.
