OK tak som zagooglil a zistil ze kecup ma k tomato paste blizsie ako pretlak :-P

pretlak - tomato purée - is a processed food product, usually consisting of only tomatoes

pasta - tomato paste - is a thick paste made by adding sugar to ripened tomatoes with skin and seeds removed.

kecup - The ingredients in a typical modern ketchup are tomato concentrate, spirit vinegar, corn syrup or other sugar, salt, spice and herb extracts (including celery), spice and garlic powder.
