The level of acid in ketchup (catsup) mainly depends on the amount of vinegar (acetic acid) used, the other major constituents being tomato solids, sweeteners, salt, and spices. The pH normally varies from 3.89 to 3.92 for commercial brands. Originally the term ketchup was applied to condiments with a base of mushrooms or even walnuts. Modern ketchup uses ripe tomatoes, which increases the thickness over ketchup made with unripened tomatoes.
