Canning is a method of preserving food over extended periods of time. The process involves sealing food in containers and heating it in order to kill bacteria that could eventually cause spoilage. While most canned food is produced by commercial companies, some is done at home. Homegrown fruits and vegetables such as apples and tomatoes are the most popular foods to can. Even certain kinds of meats are suitable for canning. However, it is not advisable to heat products such as avocados because of the changes in taste and texture that occur. Other foods, including cucumbers and peppers, can be canned only if they are first pickled and then cooked at very low temperatures. Properly canned food can be saved for as long as three years. If not properly sealed, the food can be spoiled by the growth of organisms. In severe case, bacteria can cause a fatal form of poisoning called "botulism". For this reason, it is very important to check the seal of the jar or bottle regularly to make sure it has remained undisturbed.
