Quick Answer
Vacuum sealing does not improve the shelf life of canned venison, but it can help remove air from the jar, which reduces the risk of spoilage and foodborne illness. Proper canning and storage techniques remain the primary methods for extending the shelf life of canned venison.
Safe Canning Techniques for Venison
Pressure canning is the recommended method for canning venison to ensure food safety. The USDA recommends a minimum of 30 minutes of processing time at 15 pounds per square inch (psi) for jars 1 pint or larger. Always follow a tested recipe and adjust for altitude to ensure safe canning practices.
Jar Size and Processing Time
Use jars specifically designed for canning to avoid potential issues with seal failure. Common jar sizes include 1 pint (16 oz) and 1 quart (32 oz). Processing times may vary depending on the size of the jar, the type of venison, and the altitude at which you are canning. As a general rule, a minimum of 30 minutes at 15 psi is required for a 1-pint jar, while a 1-quart jar requires 45 minutes at the same pressure.
Shelf Life and Storage
Canned venison can be safely stored for up to 12 months when stored properly. Keep jars in a cool, dark place, and avoid storing them in direct sunlight or near a heat source. Always check the seals before storing the jars, and discard any jars that have a loose or broken seal.
