Do you need lemon juice when pressure canning tomatoes?
The answer to the question is “Yes, to ensure safety, acid in the form of lemon juice, citric acid or vinegar must be added to tomatoes that will be processed in a canner.” The long answer is that the acidity of the tomato is determined by the type of tomato and the temperature at which it is processed.
The pH of a tomato can range from about 4.5 to 6.0, depending on the variety of tomatoes used, the amount of acid added, and how long it has been stored at room temperature. If the pH is too low, it will not be able to neutralize the acids that are naturally present in tomatoes, which can lead to discoloration and loss of flavor.
On the other hand, too high a pH can result in an off-flavor that can be difficult to eliminate.

Pressure canning is the only safe method of canning low-acid foods (those with a pH of more than 4.6). All vegetables, meats, poultry and seafood are included. Because of the danger of botulism, these foods must be canned in a pressure canner that has been approved by the FDA.
The temperature at which foods can be canned depends on several factors, including the type of food and the method used to can it. Generally speaking, the lower the temperature the less time it will take for the food to be safe to eat. However, there are some exceptions to this general rule.
For example, foods that have a high acid content (such as tomatoes) may take longer than foods with lower acid contents to reach safe levels of acidity. In addition, some foods, such as canned tomatoes, may be more susceptible to spoilage if they are canned at a higher temperature than they would be at room temperature.
