How to store tomato paste
Store closed tomato paste in a dry, dark place at room temperature, tomato paste is an unpretentious product. But the open paste is best filled with oil for storage for 3 days or frozen – up to a month.
How to store opened tomato paste
The best way to store open tomato paste for a long time is to freeze it. You can freeze it in an open jar or in a vacuum bag. The frozen tomato paste is stored in the freezer, separating the required amount as needed.
Silicone trays for ice or baking are also suitable. In them, tomato paste is laid out little by little, and you get convenient portions for one-time use, which are stored in the freezer.
If you need to store for a short time
To store a small amount of tomato paste in an opened container, you can pour 1-2 tablespoons of vegetable oil on the surface of the tomato paste and close the lid tightly. This will protect the product from bacteria and mold spores in the air for a couple of days.
Mustard is also used as a preservative to preserve tomato paste. It needs to be applied to the edges of the tomato paste jar and the inside of the lid – so we will extend the shelf life by another couple of days.
