How is retort Pouch used
The food is first prepared, even raw or semicooked, and then sealed into the retort pouch. The pouch is then heated to 240-250°F (116-121°C) for several minutes under high pressure, inside retort or autoclave machines. The food inside is cooked, similar to pressure cooking. The packaging process is very similar to canning, except that the package itself is flexible. The lamination structure doesn't allow permeation of gases from outside into the pouch.
POPULARITY In the consumer market, retort pouches have gained great popularity outside of the United States, particularly in the Pacific Rim region. Tuna canns have been replaced by retort pouches. Brands such as Capri Sun, Tasty Bite etc have extensively used such pouches. |
