The Optimal Storage Location for Tomato Paste
Introduction: Tomato paste is one of the most prominent natural seasonings and flavor enhancers used extensively in Iranian cuisine and globally. It is produced through the cooking and evaporation of water from tomatoes combined with salt, and is typically stored in two forms: homemade and industrially processed.
Given that tomato paste is used to enhance the aroma, flavor, and color of dishes, maintaining its quality and ensuring its safety is paramount—so much so that it should be handled as if it were freshly made. Due to the sensitivity of this perishable ingredient, it cannot be stored casually in home environments. Therefore, this section of Geranaz Magazine is dedicated to the proper storage methods and the secrets to long-term preservation of tomato paste, under the title: “The Best Place to Store Tomato Paste.”

Properties of Tomato Paste
Alongside proper storage techniques and identifying the optimal storage locations, it’s valuable to understand the health benefits of this product. In addition to its appealing aroma and flavor, tomato paste offers numerous health advantages, including:
- Rich Source of Lycopene: Tomato paste is abundant in lycopene, a potent antioxidant that helps reduce free radicals in the body. Lycopene becomes more active during cooking, contributing to the prevention of cardiovascular diseases and certain cancers, especially prostate cancer. This is arguably the most significant health benefit of tomato paste regarding cancer prevention.
- Contains Vitamins C and A: These vitamins are essential for strengthening the immune system and enhancing the body’s defense mechanisms against infections and illnesses.
- Antioxidant Content: The antioxidants in tomato paste help mitigate sun damage and protect skin health. They also shield the skin from harmful UV rays.
- Cholesterol Regulation: Regular consumption can lower LDL (bad) cholesterol and raise HDL (good) cholesterol levels, as well as help maintain normal blood pressure.
- Vision Health: Vitamin A in tomato paste supports eye health and plays a crucial role in preventing ocular conditions such as macular degeneration.
- Bone Strengthening and Osteoporosis Prevention: Lycopene contributes to bone health and helps prevent osteoporosis.
- Weight Management: Due to its high fiber content and low caloric value, tomato paste can be an effective component in weight loss diets.

Secrets to Long-Term Preservation and Extended Shelf Life
To ensure prolonged freshness and quality of tomato paste, several key points and methods should be observed:
- Use Appropriate Containers: Store tomato paste in glass jars, high-quality plastic containers, or metal cans. Avoid using iron or aluminum containers, as chemical reactions may compromise the aroma and flavor.
- Protect Against Air Exposure: Ensure containers are tightly sealed and hermetically closed to prevent oxygen ingress, which can lead to oxidation and deterioration of quality.
- Refrigeration After Opening: Once opened, keep tomato paste in the refrigerator to inhibit bacterial growth and prolong freshness.
- Use Olive Oil Layer: Some prefer to cover the surface of the paste with a thin layer of olive oil, which acts as a barrier against air contact and oxidation.
- Prevent Contamination: Always use clean, dry spoons when handling tomato paste to avoid introducing bacteria or other contaminants.
- Use Salt as Natural Preservative: Salt can naturally extend shelf life by preventing microbial growth.
- Freezing: For long-term storage, tomato paste can be frozen in small portions or suitable containers.
The quality of the tomato paste itself also plays a significant role in its preservation. Do you know how to select the best tomato paste?
The best place to store tomato paste
Whether you are using homemade or industrial tomato paste, selecting the proper storage environment is essential. While industrial products benefit from a sterilization process that extends shelf life, proper storage practices are necessary for both types.
Before recommending specific storage spaces, consider that the optimal storage location is directly related to the time elapsed after opening or unboxing the container. For example:
Storage of Unopened or Homemade Tomato Paste:
- Keep in a cool, dry place: Store in a dry and cool environment, ideally between 10°C and 21°C.
- Darkness: Place in a dark area such as a pantry or cupboard, away from direct sunlight, to prevent light-induced degradation.
Storage of Opened Tomato Paste:
- Refrigerator: Store opened tomato paste in the refrigerator to prevent bacterial growth and preserve quality.
- Suitable Containers: Use airtight glass or plastic containers for storage. Avoid metal containers at this stage to prevent reactions.
- Freezing: For extended preservation, freeze the paste in small portions or suitable containers.
