Canned foods are considered to be a convenient source of essential nutrients. Today, almost all types of foods are found in cans and can be stored for a long period of time. Most commonly canned food includes fruits, vegetables, beans, soups, meats, and seafood.
The canning process is a method to preserve the food in airtight jars or containers for longer time storage by sealing them to a temperature (usually around 240° F (116° C)) that destroys micro-organisms.
There are three main steps of canning that include:
• Processing: Food is peeled, sliced, chopped, pitted, boned, shelled or cooked.
• Sealing: The processed food is then sealed in airtight jars or cans.
• Heating: Cans or jars are heated to kill harmful bacteria that cause food spoilage.
Canned Food is considered to be less nutritious than fresh food but research shows canning does preserve most of a food's nutrients. Most of the minerals and fat-soluble vitamins, protein, carbs, and fat are not affected during the canning process. Canned food can be bought at affordable prices, even lower than fresh food.
