Quick Answer
Glass jars can break during pressure canning if not used correctly, which may lead to contamination and spoilage of the food being processed.
Choosing the Right Jar Size
When it comes to pressure canning venison, using the right jar size is crucial. A general rule of thumb is to use jars that are 16 ounces (475ml) or larger, as these can be sealed more securely and withstand the high pressures of the canning process. Using smaller jars can lead to a higher risk of breakage and spoilage.
Pressure Canning Techniques and Times
To ensure safe canning, it’s essential to follow specific processing times for different types of meat, including venison. A pressure canner should be heated to 10-15 PSI (69-103 kPa) for 90 minutes for high-acid foods, and a minimum of 60 minutes for low-acid foods like venison. It’s also crucial to monitor the pressure gauge and temperature to prevent over-processing, which can lead to a loss of flavor and texture.
Safe Storage and Shelf Life
Once canned, it’s essential to store the jars in a cool, dark place to ensure a long shelf life. When stored properly, venison can be safely consumed for up to 12 months. Before consuming, always check the jar for signs of spoilage, such as swelling, rust, or mold. If in doubt, it’s best to err on the side of caution and discard the jar to avoid foodborne illness.
