Canning mixed vegetables
Vegetables must be canned in a pressure canner for the correct time and pressure (PSI) to ensure their safety. If not canned correctly, these low acid foods may contain the deadly botulism toxin.
Vegetables may be canned without salt. Salt adds flavor but does not prevent spoilage. If you use a weighted-gauge canner and can at an altitude less than 1000 feet, you may use 10 PSI instead of 15 PSI for the canner pressure. This will improve nutrient and quality retention of the vegetables. Check with your local county extension office or Soil Conservation District for altitude information.
