How long can I store tomato paste in the freezer?
Tomato paste can be safely stored in the freezer for up to 6-8 months. However, it’s best consumed within 3-4 months for optimal flavor and texture. After thawing, make sure to check the paste for any signs of spoilage, such as an off smell or slimy texture. If it looks and smells fresh, it’s good to use.
It’s also important to note that the quality of the tomato paste before freezing affects its shelf life. Fresh, homemade tomato paste tends to have a shorter shelf life compared to store-bought varieties. This is because homemade paste may not have gone through the same sterilization process, making it more prone to spoilage. So, be sure to label and date your frozen tomato paste to keep track of how long it’s been stored.
Can I freeze tomato paste in glass jars?
It’s not recommended to freeze tomato paste in glass jars, as they can break or shatter due to the expansion of the paste during the freezing process. Glass jars are more prone to thermal shock, which can cause them to crack or shatter. Instead, consider transferring the paste to airtight, freezer-safe containers or freezer bags to prevent freezer burn and other issues.
Freezer bags are an excellent option for storing tomato paste, as they can be labeled and dated, and they take up minimal storage space.
