Preservation

Home food preservation is a way to preserve the freshness of homegrown or locally purchased foods. Methods include canning, freezing and drying. Whether you have excess produce from your garden, or you simply want to preserve your own jam, SDSU Extension provides established and trusted research-based food preservation information.

Canning

Canning is a method used for the preservation of a variety of foods, including vegetables, fruits and meats.

Freezing

Freezing is an easy and convenient method of preserving food. However, freezing does not kill bacteria, rather freezing slows down the growth of bacteria and enzyme activity- which affects the quality of the product over time.

Dehydrating

Drying or dehydrating is one of the oldest methods of food preservation. Drying removes moisture from the food and slows enzyme activity. Dried foods take up less storage space and do not require refrigeration.
