    I didn't know where else to put this.

    What did we use to keep things air tight before the use of plastic? We must have used domething or else bread would go bad in a day.

    Those are not exactly air-tight :wink:

    I think people just avoided storing food for too long. You can for example keep the separate ingredients of bread (flower, yeast etc) in a dry place and they'll stay fresh for a long time. Then before every meal (or once a day) you would bake simple breads or pancakes of it, which you consume before they would go bad.

    And meat and fish would quickly be salted, dried or smoked after killing the animal, so it'll stay fresh outside an air-tight container.

    uuh what about in Japan. They eat raw fish all the time.

    I'm not sure a barrel would be air tight. A jar might work but, jars can only hold so much.

    A cooper could easily make a water tight barrel but maybe air tight would be pushing it. Corked bottles and jars would indeed be airtight. The first experiments with the canning process were with glass jars and were proven to maintain an airless environment.

    Raw fish is best eaten fresh. If ice were available, it could be frozen.

    Perhaps natural rubber from the tree?

    I think that in old wooden sailboats they used Tar (or equivalent) between wood planks to make wooden hulls water tight? Not sure. It might not be meant to be "air" tight so much as water tight but just in case this helps you in some way.

    Oh dear. I suddenly feel old. The bread, and much more besides, did go off quickly. That was why we bought it every day. I grew up without a refrigerator, which in the fifties and even into the sixties, was a luxury item in the UK.
    Going back further preservation of meats with salt was commonplace. Or they could be smoked.

    I don't think preservation was accomplished through air tight containers. I do know though that vacuums and so maybe air tight containers could be created a long time ago.

    I can't remember the name right now, but a scientist created a vacuum between two containers and tried to seperate them with 16 horses but couldn't. Who was he?...

    One technique to take care of rotten meat was to cover it with spices. Then it wouldn't taste as bad.

    Canning, process of preserving food by heating and sealing it in airtight containers. The process was invented (1809) by Nicolas Appert, a French confectioner. In the Appert process, the food was cooked in open kettles and placed in glass jars, which were sealed by corks wired in place. The jars were then heated by submersion in boiling water. Commercial canning was introduced into the United States in 1821 by the William Underwood Company of Boston.
