In the US, tomato purée is a processed food product, usually consisting of only tomatoes, but can also be found in the seasoned form.
It differs from tomato sauce or tomato paste in consistency and content; tomato purée generally lacks the additives common to a complete tomato sauce and does not have the thickness of paste.
[4] The standard consistency of tomato puree is more than or equal to 7% but less than 24% natural total soluble solids.
[5] Passata di pomodoro is an uncooked tomato purée, strained of seeds and skins.
[6][7] Passata derives from the Italian verb passare, meaning 'to go through'.
