I have a quick question..Can I can yellow tomatoes with my red ones and is there any thing I should do special...Thanks from Texas with a garden full..

Yes you can can yellow ones, just follow the USDA advice re canning low acid veggies.

Jeannine -
I'm assuming yellow tomatoes have lower acidic values than red ones. Is that true? I'm new at canning so hope this question is not too dumb.

Also, many tomato canning recipes require hot peppers which don't appeal to my husband and me. Can I substitute milder peppers for the hot ones? For example, can I substitute ancho or poblano peppers for habanaros or scotch bonnets? Would a milder pepper effect the pH or water bath times? I want to be safe. Thanks. :yes:

I was always told that yellow were low acid tomatoes. I wanted to find out how much lower the Ph was. The Red and Yellow were nearly the same. Yellow had a little more sugar content. I was driving them crazy at Cornell with Ph tests. The tomatoes advertised as low acid, had higher sugar contents, but not lower Ph levels. It appears that higher sugar content is perceived as lower acid. I measured 16 varieties of tomatoes. Maybe low acid tomatoes exist, but I couldn't find them. I still have the report from Cornell somewhere. I remember that they all tested between 4.59 and 4.62, and test accuracy was something like +/-.03.

Good to know that, Hotwired. I think this topic keeps coming up and I seem to remember Carolyn saying that yellow tomatoes do not have lower acid, but good to have verification from your recent Cornell tests.

I do believe that sugars cover up the acid in yellows. Azoychka is a yellow that has no sweetness, and enough acid zing to pop your eyeballs.

I get paranoid every time I add a low acid veggie I pressure can my tomatoes. I also do not like a ton of vinager so I feel it is safer that way
