Natto, a traditional Japanese dish made from fermented soybeans, is known for its distinct taste and health benefits. Due to its perishable nature, many people wonder how long natto can last in the freezer. Freezing natto can be a convenient way to keep it fresh for longer periods of time.
When properly stored in the freezer, natto can last for up to six months. However, it is important to note that the texture and taste of natto may change after freezing. Freezing can cause the soybeans to become slightly mushy, and the sticky texture of the dish may be altered. Despite these changes, frozen natto can still be enjoyed and used in various dishes.
To prolong the shelf life of natto in the freezer, it is recommended to transfer it into an airtight container or freezer bag. This will help prevent freezer burn and maintain its quality. Before freezing, it is advisable to separate the individual servings of natto to make it easier to thaw and consume later.
When you’re ready to use frozen natto, simply place it in the refrigerator to thaw overnight. Once thawed, it is important to consume the natto within 24 hours to ensure its freshness. It is not recommended to refreeze thawed natto, as it can lead to further changes in texture and taste.
In conclusion, freezing natto can extend its shelf life up to six months. While the texture and taste may be slightly altered, frozen natto can still be enjoyed and used in various recipes. By properly storing frozen natto in an airtight container and thawing it in the refrigerator, you can ensure its quality and prolong its usability.

Factors That Affect the Shelf Life of Frozen Natto
When it comes to freezing natto, there are several factors that can affect its shelf life. Understanding these factors can help you ensure the quality and safety of your frozen natto.
Quality of Fresh Natto
The quality of fresh natto has a significant impact on its frozen shelf life. If the natto is not in its best condition before freezing, its overall quality may deteriorate rapidly in the freezer. Therefore, it is crucial to start with fresh and high-quality natto to maximize its shelf life.
Freezer Temperature
The temperature of the freezer plays a crucial role in preserving the quality of frozen natto. It is recommended to set the freezer temperature at or below 0°F (-18°C) to keep the natto at its best quality for an extended period. Fluctuations in freezer temperature should be avoided, as they can negatively affect the texture and taste of the natto.
Packaging
The packaging of frozen natto is vital for maintaining its overall quality. It is recommended to store the natto in airtight containers or freezer bags that are specifically designed for freezing foods. This helps prevent freezer burn and preserves the texture and flavor of the natto for a more extended period. Labeling the packaging with the date of freezing can also help track its shelf life.
Overall, the quality of fresh natto, freezer temperature, and proper packaging all play important roles in determining the shelf life of frozen natto. By considering these factors, you can enjoy frozen natto that is safe to consume and maintains its delicious taste and texture.
Signs that Frozen Natto has Gone Bad
While natto can be stored in the freezer for an extended period of time, it is important to remember that it is not completely immune to spoiling. Here are a few signs to look out for to determine if your frozen natto has gone bad:
1. Discoloration
If you notice any changes in the color of your frozen natto, such as a brown or gray tint, it may be a sign that it has gone bad. Natto should have a consistent, light yellow color when properly frozen.
2. Foul Odor
Another indicator of spoiled frozen natto is a strong, unpleasant odor. Fresh natto has a distinct aroma, but if it smells sour, rancid, or otherwise off, it is best to discard it.
If you notice any of these signs, it is recommended to err on the side of caution and dispose of the frozen natto. Consuming spoiled food can lead to food poisoning and other health risks. Always prioritize your safety when it comes to consuming perishable items like natto.
Remember: Proper storage and handling techniques can help prolong the shelf life of frozen natto, but nothing lasts forever. When in doubt, trust your senses and rely on visual cues to determine if the natto is still safe to consume.
It is essential to practice good food safety habits and discard any food that shows signs of spoilage, even if it has been stored in the freezer.
Tips for Properly Freezing Natto
If you want to extend the shelf life of natto and keep it fresh for a longer period of time, freezing is a great option. Here are some tips for properly freezing natto:
1. Choose fresh natto:
Ensure that you start with fresh natto before freezing it. Fresh natto has a better texture and taste, and it will freeze better.
2. Portion the natto:
Divide the natto into smaller portions before freezing. This will make it easier to thaw the amount you need without having to unfreeze the whole batch.
3. Use airtight containers:
Transfer the portioned natto into airtight containers or freezer bags. This will prevent moisture and air from entering and causing freezer burn.
4. Label and date the containers:
Remember to label the containers with the date of freezing. This will help you keep track of the storage time and ensure that you use the oldest natto first.
5. Remove excess air:
Before sealing the containers, remove as much air as possible. Excess air can lead to freezer burn and affect the quality of the natto.
6. Freeze at the right temperature:
Set your freezer to a temperature of -18°C (0°F) or below. This will ensure that the natto freezes quickly and maintains its quality over time.
7. Thaw properly:
When you’re ready to use the frozen natto, thaw it in the refrigerator overnight. Avoid thawing at room temperature, as it can promote bacterial growth.
Remember:
While freezing natto can extend its shelf life, it may affect the texture and taste of the fermented soybeans. It is best to consume thawed natto within a few days for the best quality.
By following these tips, you can successfully freeze natto and enjoy its unique flavor and health benefits for a longer period of time.
