Home Canning Shelf Life: A Deeper Dive
Understanding the factors that influence shelf life is essential for preserving your canned goods:
1. Acidity:
- High-acid foods (like fruits and tomatoes) naturally inhibit bacterial growth.
- Low-acid foods (like vegetables and meats) require proper processing and storage to ensure safety.
2. Proper Processing:
- Ensure proper canning methods are followed to eliminate harmful bacteria and create a vacuum seal.
3. Storage Conditions:
- Store your canned goods in a cool, dark, and dry place.
- Avoid storing them in direct sunlight or near heat sources.
