If you often choose the easy way out and buy tomato paste in a tube, you’re just like me. These tubes are convenient, still have a great taste, and actually last way longer than canned tomato paste.
Maybe you’re not using too much tomato paste, which might result in leftovers in your tube that have been sitting there for weeks. You might now be wondering if tomato paste in tubes can go bad.
If you’ve screwed the cap tightly on top of your tube, a tube of tomato paste will last for about 40-45 days, which is about 6-7 times longer than an open can of tomato paste.
