When proper canning practices are followed, the quality of fresh foods can be extended to safely consume many months beyond their usual expiration and decline in quality.

Follow Canning Guidance

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.
