Canning Tomatoes and Tomato Products (FDNS-E-43-02)Download PDF
When tomatoes are canned, they are heated hot enough and long enough to destroy organisms that can make people sick in addition to spoilage organisms. Tomatoes are treated as an acid food for canning purposes. Many tomato products may be safely canned in a boiling water canner. However, because some tomatoes can be slightly low-acid for canning purposes, added acid is required in the boiling water canning of plain tomatoes, juice and sauce.
This publication provides directions for canning a variety of tomato products as well as the equipment and procedures necessary for this type of food preparation.
