Is Tomato Sauce Ultra Processed?
Not Typically Ultra-Processed
No, plain tomato sauce is not ultra-processed. Basic tomato sauce (passata) is Level 1-2, made from just tomatoes and sometimes salt. It is among the simplest canned or jarred products available.
Key Findings
- •Plain tomato sauce (passata) with just tomatoes and salt is Level 1 — among the simplest packaged foods
- •Citric acid in canned tomato sauce is a USDA-recommended safety measure for pH standardization, not an ultra-processing indicator
- •The can lining, not the sauce contents, is the primary processing concern for canned tomato products
Why Is Tomato Sauce Level 1?
Plain tomato sauce — distinct from pasta sauce or pizza sauce with added ingredients — is one of the least processed items in the canned goods aisle. The production process involves washing, blanching, peeling, crushing, and straining tomatoes, then hot-filling into cans or jars. This is purely mechanical and thermal processing with no chemical additives. The can lining (historically BPA-based, now increasingly BPA-free) is the primary processing concern rather than the food itself. Citric acid appears in some brands to standardize acidity for safe canning — this is a food safety measure required by USDA canning guidelines when the tomato variety's pH might fall above the 4.6 threshold for safe water-bath canning. It is a minimal addition for safety rather than flavor engineering.

How to Read Tomato Sauce Labels
- 1
The simplest tomato sauce lists only "tomatoes" or "tomatoes, salt" — look for this
- 2
Citric acid in canned tomatoes is a pH safety measure, not a flavor additive — it is a minimal processing marker
- 3
Calcium chloride is sometimes added to maintain firmness in diced or whole canned tomatoes — a texture additive
- 4
Avoid tomato sauces with added sugar, soybean oil, or "natural flavors" — these are different products
Frequently Asked Questions
Is canned tomato sauce processed?
Minimally. Canned tomato sauce involves mechanical processing (crushing, straining) and thermal processing (heat for canning). With just tomatoes and possibly salt, it is Level 1-2. There are no chemical additives in basic tomato sauce.
Is tomato sauce the same as pasta sauce?
No. Plain tomato sauce is just strained tomatoes (1-2 ingredients). Pasta sauce adds oil, herbs, garlic, and often sugar, citric acid, and other ingredients (8-20 ingredients). They start from the same base but diverge significantly in processing.
Is tomato paste ultra-processed?
No. Tomato paste is tomato sauce that has been cooked down to remove water, concentrating the flavor. It typically contains just tomatoes and sometimes salt. Despite being more concentrated, it is Level 1-2.
