The main ingredients of the classic version of Heinz Tomato Ketchup include tomato concentrate from red ripe tomatoes, distilled vinegar, corn syrup, salt, spice, onion powder and flavorings. Other ketchup varieties made by Heinz have extra ingredients like Tabasco or balsamic vinegar.
Tomato concentrate, vinegar and different types of sweeteners make up the main ingredients for most brands of ketchup products. Heinz sells several types of tomato ketchup, in addition to the regular variety. The "Simply Heinz" and the "Organic" versions use sugar as main sweetener, instead of corn syrup. The low-sodium ketchup variety called "No Salt" is ideal for people who want to limit their amount of daily salt intake.
