Food preservation is the process of preventing food from spoiling or decaying, thereby extending its shelf life and ensuring its safety for consumption. There are various methods of food preservation, including canning, freezing, drying, pickling, and fermenting. These methods help to inhibit the growth of bacteria, yeast, and molds that cause food to spoil. Food preservation techniques have been developed and refined over centuries to help people store and transport food for longer periods of time, particularly in times of scarcity or to cope with seasonal variations in food availability. Today, food preservation continues to be an important aspect of food production and distribution, helping to reduce food waste and ensure a stable food supply for consumers.
