Sauerkraut is a fermented cabbage dish that originated in Germany and is popular in many cuisines around the world. It has a tangy and sour flavor and is rich in probiotics, vitamins, and minerals. Sauerkraut can be eaten as a side dish, salad, or topping for sandwiches, hot dogs, or sausages.
But how long does sauerkraut last in the refrigerator? And how can you tell if it is still good or spoiled? In this article, we will answer these questions and provide some tips on how to store and preserve sauerkraut properly.
How Long Does Sauerkraut Last in the Refrigerator?
The shelf life of sauerkraut depends on several factors, such as the type of sauerkraut, the date of purchase or production, the temperature and humidity of the refrigerator, and the packaging and sealing of the sauerkraut.
As a general rule of thumb, store-bought sauerkraut can last for up to a week in the refrigerator after opening, while homemade sauerkraut can last for up to six months or longer. However, these are only estimates and may vary depending on the specific conditions of your refrigerator and sauerkraut.
To be on the safe side, it is best to check the expiration date or sell-by date on the package of the sauerkraut before buying or storing it. If there is no date on the package, you can ask the seller or use your senses to judge the freshness of the sauerkraut.
How Can You Tell If Sauerkraut Is Bad or Spoiled?
Sauerkraut is a fermented food that contains beneficial bacteria that help preserve it and prevent spoilage. However, sauerkraut can still go bad if it is exposed to air, moisture, heat, or contaminants. Eating spoiled sauerkraut can cause food poisoning symptoms such as nausea, vomiting, diarrhea, and abdominal cramps. Therefore, it is important to know how to tell if sauerkraut is bad or spoiled before cooking or eating it.
Here are some signs that indicate that sauerkraut is bad or spoiled:
- The color of the sauerkraut changes from white or pale yellow to brown or black.
- The texture of the sauerkraut becomes soft, mushy, or slimy.
- The smell of the sauerkraut becomes foul, rotten, or ammonia-like.
- The taste of the sauerkraut becomes bitter, sour, or metallic.
If you notice any of these signs, do not eat the sauerkraut and discard it immediately. Do not try to salvage or cook spoiled sauerkraut, as it may still contain harmful bacteria or toxins that can make you sick.
How Can You Store Sauerkraut Properly and Extend Its Shelf Life?
Sauerkraut is a perishable food that requires proper storage to prevent spoilage and contamination. Here are some tips on how to store sauerkraut properly and extend its shelf life:
- Keep sauerkraut refrigerated at 40°F (4°C) or below at all times. Do not leave sauerkraut at room temperature for more than two hours, as this can increase the risk of bacterial growth and spoilage.
- Transfer sauerkraut to an airtight container or jar after opening. This will prevent exposure to air and moisture that can cause oxidation and mold growth. Make sure to leave some headspace in the container or jar to allow for expansion during fermentation.
- Submerge sauerkraut in its brine (the liquid that covers it) at all times. This will create an anaerobic environment that inhibits harmful bacteria and preserves the flavor and texture of the sauerkraut. If there is not enough brine to cover the sauerkraut, you can make more by dissolving one tablespoon of salt in four cups of water and adding it to the container or jar.
- Consume sauerkraut within six months of opening or making it. Although sauerkraut can last longer than that in the refrigerator, its quality and taste may decline over time.
- Freeze sauerkraut if you want to store it for longer than six months. Freezing will stop the fermentation process and preserve the nutrients and flavor of the sauerkraut. However, freezing may also affect the texture and color of the sauerkraut, making it softer and darker. To freeze sauerkraut, pack it in freezer-safe bags or containers with some brine and leave some space for expansion. Thaw frozen sauerkraut in the refrigerator overnight before using it.
