Low-acid foods, such as vegetables and meats, require pressure canning. Food preserved by canning or bottling is at immediate risk of spoilage once the can or bottle has been opened. Lack of quality control in the canning process may allow ingress of water or micro-organisms.
Canning of food can preserve food for a particularly long period of time, whether done at home or commercially. Canned food is vacuum packed in order to keep oxygen, which is needed by bacteria in aerobic spoilage, out of the can. Canning does have limitations, and does not preserve the food indefinitely. [14]
The heating process during canning appears to make dietary fiber more soluble, and therefore more readily fermented in the colon into gases and physiologically active byproducts. Canned tomatoes have a higher available lycopene content. Consequently, canned meat and vegetables are often among the list of food items that are stocked during ...

Le Ménagier de Paris mentions pâtés of fish, game, young rabbit, fresh venison, beef, pigeon, mutton, veal, and pork, and even pâtés of lark, turtledove, baby bird, goose, and hen.
Before refrigeration, canning and other modern preservation techniques became available, fermenting was an important preservation method. Fish rapidly spoils, or goes rotten, unless some method is applied to stop the bacteria that produce the spoilage. Fermentation is a method which attacks the ability of microbials to spoil fish.
