Canned foods are often thought to be less nutritious than fresh or frozen foods. Some people claim they contain harmful ingredients and should be avoided. Others say canned foods can be a part of a healthy diet.
Canning is a method of preserving foods for long periods by packing them in airtight containers สมัคร ufabet
Canning was first developed in the late 18th century as a way to provide a stable food source for soldiers and sailors at war.
The canning process can vary slightly by product, but there are three main steps. These include:
- Processing. Food is peeled, sliced, chopped, pitted, boned, shelled, or cooked.
- Sealing. The processed food is sealed in cans.
- Heating. Cans are heated to kill harmful bacteria and prevent spoilage.
This allows food to be shelf-stable and safe to eat for 1–5 years or longer.
Common canned foods include fruits, vegetables, beans, soups, meats, and seafood.
They may contain deadly bacteria.
While it’s extremely rare, canned foods that weren’t processed properly may contain dangerous bacteria known as Clostridium botulinum.
Consuming contaminated food can cause botulism. A serious illness that can lead to paralysis and death if left untreated.
Most cases of botulism come from foods that have not canned properly at home. Botulism from commercially canned food is rare.
It’s important to never eat from cans that are bulging, dented, cracked, or leaking.
