Fermented cabbage, or sauerkraut, is a well-known dish with numerous health benefits, including probiotics that promote gut health and boost the immune system. While it can be stored in various ways, including canning and refrigeration, one common question is whether it can be frozen, specifically in a plastic bag. Freezing sauerkraut can be a practical solution for those with large batches of this tangy superfood, but it is important to consider the potential impact on texture, flavour, and nutritional content.

What You'll Learn
Freezing sauerkraut will reduce its probiotic benefits
Yes, you can freeze sauerkraut that comes in a plastic bag. However, freezing sauerkraut reduces its probiotic benefits.
Sauerkraut is a well-known fermented food with a distinctive flavour and abundant probiotics. These beneficial bacteria are well-known for aiding digestion, enhancing gut health, and boosting the immune system. However, freezing sauerkraut can significantly impact these probiotics.
The extreme cold temperatures during freezing damage and reduce the viability of the live bacteria cultures in sauerkraut. Lactobacillus brevis and Pediococcus plantarum are two types of beneficial bacteria involved in the natural fermentation process. Freezing sauerkraut can alter the balance of these bacteria, compromising the health benefits associated with their presence.
Research indicates that freezing can reduce the population of viable probiotic bacteria in sauerkraut. While some health-promoting qualities may persist, the level of benefit depends on the freezing duration and specific strains present. Therefore, freezing sauerkraut for extended periods can lead to a more significant loss of probiotics.
To maintain the maximum probiotic benefit of sauerkraut, refrigeration is recommended. Storing sauerkraut in an airtight container in the fridge allows the probiotics to remain alive and active for months. At temperatures between 35 to 40 degrees Fahrenheit, the growth of probiotic bacteria slows down but does not stop, preserving the health benefits of sauerkraut.

Sauerkraut can be frozen for up to 12 months
Sauerkraut is a well-known fermented food with numerous health benefits. It is rich in probiotics and microorganisms that promote gut health and boost the immune system. While it is best consumed raw and fresh, freezing is a practical option to extend its shelf life, especially when dealing with large batches.
When freezing sauerkraut, it is crucial to use proper storage techniques to maintain its quality. Firstly, transfer the sauerkraut from its original bag to a freezer-safe plastic bag or a heavy-duty plastic bag. Always use airtight containers to prevent spoilage and extend shelf life. Make sure to leave about three inches of space at the top of the bag, as the liquid in the sauerkraut expands when frozen. Squeeze out as much air as possible and seal the bag tightly to avoid any leaks. Additionally, label the bag with the date of freezing. For added protection, place the sealed bag inside a plastic container and store it in the freezer.
By following these steps, sauerkraut can be safely frozen for up to 12 months. However, it is important to note that freezing may alter the texture and flavour of the sauerkraut, and it might lose some of its probiotic benefits. For optimal taste and nutritional value, it is recommended to consume sauerkraut fresh and store it in the refrigerator, where it can last for several months.

Use freezer-safe plastic bags to prevent freezer burn
Yes, you can freeze sauerkraut that comes in a plastic bag. However, it's important to note that freezing sauerkraut can reduce its probiotic benefits and alter its texture and flavour. If you choose to freeze your sauerkraut, here are some tips to prevent freezer burn and maintain its quality:
Use freezer-safe plastic bags: Always opt for plastic bags specifically designed for freezer use. These bags are made to withstand extremely cold temperatures and will help keep your sauerkraut protected from freezer burn. Avoid using regular plastic bags, as they may not handle the cold temperatures well and could increase the risk of freezer burn.
Remove as much air as possible: Air trapped inside the bag can contribute to freezer burn and damage the sauerkraut over time. Squeeze out as much air as you can before sealing the bag tightly. This helps create an optimal environment for long-term storage.
Leave some space at the top: While removing excess air is important, be sure to leave about three inches of space at the top of the bag. This allowance is crucial because the liquid in sauerkraut expands when frozen, and not having enough space can lead to leaks or bursting.
Seal the bags securely: Ensure that your freezer-safe plastic bags are tightly sealed. A secure seal prevents leaks and helps maintain the quality of your sauerkraut by keeping out air and moisture, both of which can cause freezer burn and affect flavour.
Place the sealed bags in plastic containers: For added protection, place the sealed bags inside plastic containers before putting them in the freezer. This extra layer of protection helps prevent leaks and shields your sauerkraut from potential damage caused by other items in the freezer.
Label the bags with the date: Always label your freezer bags with the date of freezing. This practice helps you keep track of how long the sauerkraut has been frozen and ensures that you use it within its recommended frozen storage time, which is typically up to 12 months.
By following these steps and using freezer-safe plastic bags, you can effectively prevent freezer burn when freezing sauerkraut in plastic bags. Remember, while freezing extends the shelf life of sauerkraut, it may slightly affect its flavour and texture, and some loss of probiotic benefits is expected.

Leave space at the top of the bag as sauerkraut expands when frozen
Yes, you can freeze sauerkraut that comes in a plastic bag. Freezing is a practical way to extend its shelf life, especially when dealing with large batches. However, it's important to note that freezing can alter the texture and flavour and may reduce the probiotic benefits.
When freezing sauerkraut in a plastic bag, it is crucial to leave space at the top of the bag. This is because the liquid in sauerkraut expands when frozen, and not leaving enough space can lead to leaks. Aim to leave about three inches of space at the top of the bag.
To ensure the sauerkraut stays fresh and reduce the risk of freezer burn, it is essential to remove as much air from the bag as possible before sealing it tightly. Place the sealed bag inside a plastic container to provide added protection and avoid potential leaks.
By following these steps, you can successfully freeze sauerkraut in a plastic bag, ensuring it stays fresh and reducing the chances of any mess or damage during the freezing process.
It is worth noting that freezing sauerkraut may affect its texture, flavour, and probiotic content, so it is recommended to slowly thaw it in the refrigerator to preserve its qualities as much as possible.

It's best to slowly thaw frozen sauerkraut in the fridge
Yes, you can freeze sauerkraut that comes in a plastic bag. It is always better to freeze leftover food than waste it. However, freezing sauerkraut can kill off the probiotics that offer health benefits. Freezing also alters the texture and flavour of the food.
If you do choose to freeze your sauerkraut, make sure to use a heavy-duty plastic bag or a freezer-safe plastic container. Leave some space at the top of the container or bag, as the liquid in the sauerkraut expands when frozen. Squeeze out as much air as possible and seal the container or bag tightly. You can also place the sealed bag inside a plastic container to avoid leaks. Properly stored, bagged sauerkraut can be kept in the freezer for up to 12 months.
When you're ready to eat your sauerkraut, it's best to slowly thaw it in the fridge. This will help preserve the flavour and texture of the food. The probiotics in sauerkraut are sensitive to temperature changes, and slowly thawing the food in the fridge will help to protect these nutrients. Place the frozen sauerkraut in a bowl in your refrigerator and let it thaw overnight, or for at least 8 hours.
Once the sauerkraut is thawed, it's best to cook it before eating. Add it to soups, stews, or casseroles. Freezing changes the texture of the sauerkraut, so it won't be as crisp as fresh fermented sauerkraut. It's also important to note that while some strains of live bacteria in sauerkraut will survive the freezing process, others will not.
