There are several types of home food preservation with the aim of converting food into a state that allows it to be stored for a long time without spoiling, while retaining some elements of the original texture and flavor. Some very popular methods, such as canning and pickling, are easily accessible to anyone over time. Other methods, such as dehydration, freeze-drying, fermentation, and salting, require advanced knowledge and sometimes special equipment to work properly. All methods used for food preservation at home use some technique to ward off harmful bacteria and prevent them from spoiling food.

Food can be kept in containers for a period of time.

One of the most important aspects of preserving food at home is preventing bacteria and other harmful organisms from reaching the food and causing it to go bad. Each home food preservation technique approaches this in a different way, sometimes through managing the food’s moisture content, sometimes changing the acidity, and other times creating a physical barrier to stop bacteria. The success or failure of the techniques is linked to maintaining very precise conditions throughout the process, which means that it is important to prepare the ingredients for preservation according to the tested techniques, as variations in the procedure can lead to unpredictable and sometimes unpredictable results. harmful.

Foods can be wrapped in plastic wrap to preserve freshness as a temporary measure.

Canning involves taking food that has been prepared, sometimes through cooking, and placing it in a sterile container filled with liquid. Glass jars with specially fitted lids are commonly used. The jars are sterilized and filled with clean food and a liquid or brine. Filled jars are closed and boiled or exposed to pressure to seal tightly, preventing bacteria from entering the can and spoiling the food. Almost everything from meat to vegetables can be canned, allowing them to be preserved for a year or more.

Using pickling as a method of preserving food at home means relying on a brine to fight bacteria. Canned foods sometimes need to be refrigerated and do not always last as long as some other methods. Meats and vegetables are commonly pickled, although items such as eggs and sausages can also be pickled. The change in the acidity of the brine and the strength of the salt keeps foods preserved, while also changing the flavor and texture over time.

Dehydration can be used to reduce the moisture content in foods. When used for food preservation at home, the lack of moisture means bacteria will have nowhere to take root, allowing food to remain edible much longer. Fruits, some vegetables and some meat can be dehydrated and eaten dry or later reconstituted with water. The process can be carried out with a special dehydrating machine or by means of drying in the open air under controlled conditions.

Food fermentation can be used for home food preservation. This involves allowing beneficial bacteria to interact with food to create elements such as lactic acid, forming a hostile environment for harmful bacteria. Depending on the type of fermentation, food can be stored for a long time under the right conditions, sometimes allowing fermentation to continue. Other techniques stop the fermentation process and then can the food for long-term storage.
