Tomato ketchup and tomato sauce are among of the most popular food condiments. Typically, they are made of tomato concentrate or whole peeled tomatoes. Ketchup and tomato sauce also contain water, sugar, vinegar, salt, seasoning, and a starch-based thickener.
The ketchup is produced by diluting tomato paste or tomato puree with water to the desired Brix. After that, other ingredients such as sugar or sweetener, salt and preservatives are added to the mixture according to the recipe.
Next, mixed tomato paste proceeds to sterilization and de-aeration. Afterwards, it will be homogenized for required consistency.
