What it is

Onion tomato paste is a concentrated product made from cooked, pureed tomatoes and onions. The ingredients are typically simmered to reduce water content and intensify their flavors, then often strained to remove skins and seeds. It serves as a base for sauces, soups, and other savory dishes.

Why it's used

Manufacturers use onion tomato paste to add a rich, savory, and slightly sweet flavor to foods. Its concentrated nature makes it a potent flavor enhancer. It is commonly found in dips and salsa, frozen dinners, ketchup, mustard, and barbecue sauces.

Health notes

Onion tomato paste is generally recognized as safe (GRAS) by the FDA when used as a food ingredient. It is a source of vitamins and antioxidants, such as lycopene from tomatoes. Regulatory bodies like JECFA and EFSA have evaluated similar tomato-based products. Evidence does not suggest adverse health effects from consuming onion tomato paste at typical dietary levels.

Allergen info

Not a major allergen. Onions and tomatoes are not among the nine major food allergens recognized by the FDA.
