Canning Tomatoes with Citric Acid: A Guide to Safe and Delicious Preserves
Want to enjoy the taste of summer all year long? Canning tomatoes is a great way to preserve the bounty of your garden or local farmers market. But did you know that using citric acid in your canning process is essential for safety?
Citric acid acts as a natural acidifier, lowering the pH of tomatoes and making them less hospitable to the growth of dangerous bacteria like Clostridium botulinum, the cause of botulism poisoning. This is especially important when canning tomatoes, as they are naturally low in acidity.
Why Use Citric Acid?
- Safety: Citric acid ensures the safe preservation of tomatoes by inhibiting bacterial growth.
- Flavor: Citric acid adds a subtle tang to your canned tomatoes, enhancing their flavor.
- Convenience: Citric acid is readily available at most grocery stores and online retailers.

- Use the right canning method: Make sure to follow the appropriate canning method for tomatoes, either a hot water bath or pressure canning, depending on your recipe and altitude.
Benefits of Using Citric Acid:
- Increased shelf life: Citric acid helps extend the shelf life of your canned tomatoes, ensuring they stay fresh and flavorful for longer.
- Reduced risk of spoilage: By lowering the pH, citric acid minimizes the risk of spoilage and the growth of harmful bacteria.
