Cento couldn't use San Marzano, the article states he left those out of the test.
I also left out any brands that used San Marzano tomatoes, just to be fair (because if you’ve had these types of tomatoes, you know how good they are!).
As for the citric acid, I don't believe any of the brands add citric acid. Tomatoes are naturally acidic. My wife also is very sensitive to acid--she gets it from citrus, some wines and tomatoes. I do want to find some San Marzano tomatoes though. All I've ever had are Romas--that is what the three CA brands use. Romas have no flavor IMHO, but I haven't had a really good table tomato in many years either.
I was going off memory from the most recent issue of Cook's Illustrated/America's Test Kitchen.
The article (May & June 2024 issue) on "The Best Whole Canned Tomatoes".
Okay - two issues here, so in order;
1st: Seems I can't get into the Cook's Illustrated website to copy-paste that recent article. Might have to wait several months to a couple years before they release it to general public access. So I'll summarize below. I will recommend going to your preferred newstand/magazine rack and you should be able to find and purchase this recent issue for your own validation. (Also worth considering getting a subscription.)
The article shows about nine brand/cans of whole, peeled tomatoes and text reveals that for most of them they are using "San Marzano - style" tomatoes. An USA grown variant.
However the article text shows the ingredients from the label of the Cento, imported from Italy, brand/can and this was the one they rated as top. The ingredients were: San Marzano whole peeled tomatoes, San Marzano puree, sea salt, basil leaf.
A bit more expensive at about $0.16/oz. vs. others at about $0.09/oz. But worth the extra for taste and texture. (Assuming you can find at a local store.)
FWIW, we have San Marzano seeds and grew some last year and have starts going now for this year's planting.
2nd: Citric acid is a frequent ingredient in many foods and my wife has researched this and in most cases it is made using wheat, which is one of several foods/combinations she has sensitivities to. Not the same as an allergy, but not pleasant since it causes migranes and other distress. Point being she has a few such issues, some are actual whole foods, like wheat, potatoes, coconut, etc. and also products made from them. Such as maltodextrin, dextrose, and citiric acid, etc. Believe me, we've been checking this stuff out for years now and when in doubt, we avoid any foods with these, and others, on the ingredients labels.
If interested, here's another article from their website on various types of canned tomatoes.
