The Science behind pH
When ingredients dissolve in water (H20), they produce ions H+ and OH–. If there are more hydrogen (H+) ions, the solution is acidic. If there are more hydroxyl (OH–) ions, it is alkaline or basic. Therefore, acidity is determined by measuring the potential hydrogen, abbreviated pH. The pH can range from 0 to 14.
Citric acid, vinegar, and lemon juice
The following acids are available to increase the acidity (lower the pH) in tested canning recipes when canning tomatoes safely at home:
Which acid is best for canning tomatoes?
Last year, I canned pint jars using each of these three types of acid, with and without sugar. In all jars, I used the same batch of locally grown, field-ripened San Marzano tomatoes. This paste-type tomato is very sweet when fully ripe. For each type of acid, I found that the canned tomatoes without sugar tasted slightly better.

I cooked down a pot of tomatoes and pressure canned them. I realized after they were cool that I forgot to add the lemon juice. They are just tomatoes and herbs, and were pressure canned for 20 minutes. The lids are all sealed and they look good. Should I be worried or will they be OK without the added acidity?

They should be fine, especially if the tomatoes were of an older variety. I'd mark them and use them first.

Netty, I did the same thing this year but most of the tomatoes I used were heirlooms so I think they will be fine. When I first started canning the recommended time was a 30 min water bath for quarts, with no lemon juice, but that was 46 years ago.

Thanks folks, I was hoping you would say that. After all the time it took to grow, peel and process it would break my heart to dump them out! They have been labeled as 'tomatoes no lemon' and are at the front of the pantry. I did another batch today and made sure to follow the directions to the letter.

Netty, according to this, pressure-canned tomatoes will be safe, even though you didn't add an acid.

I agree with maringardener. You are alright if you pressure canned them. You are safe...
