Ketchup
In Canadian markets, the manufacturing of ketchup is regulated by the Food and Drug Regulation. Ketchup, a heat processed product, must be made from the juice of red-ripe tomatoes or sound tomato trimmings where the skins and seeds have been removed. The ketchup must contain vinegar, salt, seasoning and a sweetening ingredient. They may also contain a class II preservative and food colouring, though not required.
