Natto is a traditional Japanese food made from fermented soybeans. It is known for its distinct smell and slimy texture. Many people wonder whether natto needs to be refrigerated or if it can be stored at room temperature. In this article, we will explore the topic and discuss the best way to store natto.
The fermentation process used to make natto gives it a unique flavor and texture. During fermentation, beneficial bacteria called Bacillus subtilis convert the soy proteins into simpler compounds, which results in the gooey consistency and potent smell of natto.
So, does natto need to be refrigerated? The answer is yes. Natto should be stored in the refrigerator to maintain its freshness and prevent the growth of harmful bacteria. While natto is fermented, it is not a fully preserved food like cheese or sauerkraut. It is still susceptible to spoilage if not stored properly.
The Origin of Natto
Natto, a traditional Japanese dish, has a long history that dates back over a thousand years. It is believed to have originated in the northeastern region of Japan, particularly in the Tohoku region, where it was first made by fermenting soybeans with Bacillus subtilis, a type of bacteria found in the soil.
The exact origins of natto are unclear, but it is thought to have been discovered accidentally. Legend has it that samurais in ancient Japan used to carry cooked soybeans with them during battles. Due to the warm and humid climate, the beans would often become moldy. However, the samurais discovered that the fermented beans had a unique taste and aroma.
Over time, the fermentation process was refined, and natto became a popular food in Japan. Today, it is enjoyed throughout the country and is often eaten as a breakfast staple alongside rice or other dishes.
The unique texture and flavor of natto can be attributed to the fermentation process. During fermentation, the bacteria break down the proteins and starches in the soybeans, creating a sticky and slimy texture. Additionally, the bacteria produce an enzyme called nattokinase, which gives natto its distinct taste and smell.
While natto is a traditional Japanese food, it has gained popularity worldwide due to its health benefits. It is rich in protein, vitamins, and minerals, and is packed with probiotics that support gut health. Many people consider natto to be a superfood and incorporate it into their diets for its nutritional value.

Natto Production Process
Natto is a traditional Japanese food made from fermented soybeans. The production process involves several steps that contribute to its unique taste and texture.
- Selection of Soybeans
- Steaming
- Inoculation
- Fermentation
- Packaging
High-quality soybeans are carefully selected for making natto. The beans should be free from any damage or contamination.
The selected soybeans are steamed to make them soft and plump. Steaming helps in breaking down the complex carbohydrates and proteins present in the beans.
After steaming, the soybeans are cooled down to a specific temperature, and a natto starter culture is added. The starter culture contains bacteria called Bacillus subtilis, which ferments the soybeans.
The inoculated soybeans are placed in a warm and humid environment to facilitate fermentation. The bacteria in the starter culture produce enzymes that break down the proteins into smaller compounds, giving natto its characteristic slimy texture and strong odor.
Once the fermentation process is complete, the natto is packaged in small containers or plastic trays. It is important to keep the product sealed properly to maintain its freshness.
It is worth mentioning that natto should be refrigerated after the production process to prevent further fermentation and maintain its quality. Storing natto in the refrigerator helps to slow down the growth of bacteria and maintain its taste and texture for a longer period of time.
Proper Storage of Natto
Storing natto properly is essential to maintain its quality and prevent harmful bacterial growth. Here are some tips to ensure that your natto stays fresh and safe:
Refrigeration
While natto does not necessarily need to be refrigerated, it is highly recommended to do so. Refrigerating natto helps slow down the fermentation process and extends its shelf life.
Sealed Container
After opening the natto package, transfer the remaining contents to an airtight container. This helps prevent exposure to air and moisture, which can affect the texture and taste of the natto.
Cool and Dark Place
When storing natto, choose a cool and dark place in your refrigerator. Avoid placing it near strong-smelling foods as natto tends to absorb odors.
Important Note: If you notice any unusual smell, discoloration, or sliminess, it is best to discard the natto to avoid the risk of foodborne illnesses.
Properly storing natto not only maintains its quality but also ensures food safety. By following these simple guidelines, you can enjoy your natto for a longer period.
Health Benefits of Natto
Natto, a traditional Japanese food made from fermented soybeans, is not only loved for its unique flavor and texture but also renowned for its numerous health benefits. Here are some of the key health benefits of including natto in your diet:
| Benefit | Description |
|---|---|
| High in Protein | Natto is a great source of plant-based protein, making it an excellent choice for vegetarians and vegans. It contains all the essential amino acids, making it a complete protein source. |
| Rich in Vitamin K2 | Natto is one of the few food sources that are naturally high in vitamin K2. This vitamin plays a crucial role in bone health by helping to regulate calcium metabolism and promote bone mineralization. |
| Gut Health | Being a fermented food, natto is rich in beneficial bacteria known as probiotics. These bacteria can help improve gut health by promoting the growth of beneficial gut bacteria and aiding digestion. |
| Cardiovascular Health | Natto contains a compound called nattokinase, which has been shown to have anticoagulant properties. This can help prevent blood clot formation and improve blood circulation, thus reducing the risk of cardiovascular diseases. |
| Anti-Inflammatory | Natto contains a variety of bioactive compounds, including pyrazine, that have been found to possess anti-inflammatory properties. Regular consumption of natto may help reduce inflammation in the body and alleviate symptoms of inflammatory conditions. |
Overall, natto is a nutritious food that can be a valuable addition to a healthy diet. However, it is important to note that some individuals may have an aversion to its strong flavor and aroma. If you enjoy the taste and are not sensitive to soybeans, incorporating natto into your meals can provide you with these beneficial health effects.
FAQ
Should natto be refrigerated?
Yes, natto should be refrigerated in order to maintain its quality and prevent the growth of harmful bacteria. Storing natto in the refrigerator helps to preserve its texture and flavour.
Can natto be stored at room temperature?
No, it is not recommended to store natto at room temperature. Natto is a fermented soybean dish that contains live bacteria, which can multiply rapidly at room temperature and cause spoilage. Therefore, it is essential to refrigerate natto to keep it fresh and safe to consume.
