According to SAEDNEWS, Tomato paste is one of the most commonly used ingredients in cooking, but it can quickly develop mold if it is not stored correctly. After opening a jar or can, exposure to air and moisture creates the perfect conditions for mold to grow. Using proper storage techniques can help keep the paste fresh and safe for a longer period.

One important step is to always use a clean, dry spoon when taking tomato paste from the container. A wet or dirty spoon can introduce bacteria and moisture, which speeds up spoilage. It is also better to transfer opened tomato paste into a clean glass container with a tight lid instead of leaving it in the original can.

Adding a thin layer of oil on the surface of tomato paste is another useful method to prevent mold. The oil creates a barrier between the paste and the air, slowing down oxidation and fungal growth. Before each use, you can remove the old oil layer if needed and add a new small amount to protect the remaining paste.

Keeping tomato paste in the coldest part of the refrigerator and closing the lid tightly after every use also helps maintain its quality. For longer storage, you can divide the paste into small portions and freeze them. These simple habits keep tomato paste fresh, flavorful, and ready to use whenever you need it.
