Canning Food for Emergency Storage
Understand home canning as a food-preservation method and why tested recipes and correct processing are essential.
Home canning is not a place to improvise process times or acidity. The National Center for Home Food Preservation recommends current research-tested procedures because unsafe canning can allow dangerous toxin formation.

Low-acid foods require special care
Low-acid foods require special care is best approached as part of a system rather than as an isolated trick. Match the food, packaging, preparation needs and storage conditions to the emergency you are planning for. When a method controls pathogens, acidity, moisture or processing temperature, use a current tested recipe or official procedure rather than adjusting times, ratios or temperatures by intuition.

When in doubt discard

Safety sources to keep handy
For preservation methods where process details affect safety, use current research-tested guidance rather than improvising.
