Food preservation is the process of treating and handling food to stop or slow down spoilage, ensuring it remains safe and tasty for longer periods. Common methods include refrigeration, freezing, canning, and drying. These techniques help to prevent the growth of harmful bacteria and mold, allowing us to enjoy seasonal foods year-round. Another important aspect of food preservation is the use of packaging and storage techniques. Vacuum sealing, for example, removes air from packages, which helps to keep food fresh. Additionally, pickling and fermentation are traditional methods that not only preserve food but also enhance its flavor and nutritional value.
