"Canning is a method of food preservation in which food is processed and sealed in an airtight container (jars like Mason jars, and steel and tin cans)."
Canning is the process of preserving and packaging food in airtight containers to extend its shelf life and maintain its nutritional value.

Water bath canning: This is a method of canning that involves submerging jars of food in boiling water for a set amount of time. This type of canning is used for high-acid foods such as fruits, pickles, and tomatoes.
Pressure canning: This method of canning involves cooking food at a higher temperature and pressure than water bath canning. This is used for low-acid foods such as meats, poultry, and vegetables.
Open-kettle canning: This is an unsafe method of canning where food is cooked in an open pot and poured into jars, sealed, and cooled. This method is not recommended due to the risk of bacteria growth and contamination.
Steam canning: This method uses steam to heat the food and jars instead of submerging them in water. It can be used for acidic foods, but is not recommended for low-acid foods.
Freezer canning: This method involves packing foods into freezer-safe containers and storing them in the freezer. This method is best for foods that do not require a long shelf life.
Solar canning: This is a method of canning that uses the sun's heat to process the food. This method is best for fruits and vegetables.
Dry canning: This is a method of canning where the food is dehydrated before being packed into jars. This method is best for fruits and vegetables.
Pickling: Pickling involves submerging fruits or vegetables in a brine solution of vinegar, salt, and sugar. Pickles, relishes, and chutneys are common pickled foods.
Fermentation: Fermenting is a process that involves allowing the food to sit at room temperature in a solution of saltwater. Sauerkraut, kimchi, and pickles are commonly fermented foods.
Preservation: Preservation involves treating food in a way that prevents spoilage or decay. Smoking, salting, and drying are common preservation methods.
"Canning provides a shelf life that typically ranges from one to five years, although under specific circumstances, it can be much longer."
"A freeze-dried canned product, such as canned dried lentils, could last as long as 30 years in an edible state."
"The 109-year-old food was determined to be still safe to eat."
"Samples of canned food from the wreck of the Bertrand, a steamboat that sank in the Missouri River in 1865, were tested by the National Food Processors Association."
"Although appearance, smell, and vitamin content had deteriorated..."
"There was no trace of microbial growth."
