language culture Maturity 5-7 Next article →

Miso is a traditional Japanese seasoning used as a thick, savory paste.

It is a fundamental part of Japanese cuisine and a vital source of nutrition. The paste is high in protein and rich in minerals. For centuries, it provided essential nutrients in feudal Japan. Today, it is used globally in various culinary applications. People use it for sauces, spreads, and pickling meats or vegetables. It is most famously used to make miso soup, a staple food often paired with rice.

The production of miso involves a complex two-step fermentation process. First, producers must create a starter culture known as kōji. This is made by introducing the fungus Aspergillus oryzae onto steamed grains, such as rice. This aerobic fungus is essential because it produces two types of enzymes. Amylolytic enzymes, like amylase, break down starches into sugars and dextrin. Proteolytic enzymes, like protease, break down proteins into peptides or amino acids.

Second, this kōji is combined with soybeans and salt. This mixture is left to undergo enzymatic digestion and aging. The fermentation time can range from only five days to several years.

Miso varieties are classified by their ingredients, color, and taste. One common type is shiro miso, or white miso. It is made primarily from rice, barley, and a small amount of soybeans. Because it has a short fermentation period, it tastes sweet and light. Another major variety is akamiso, or red miso. This type is aged for a long time, sometimes over a year. During this time, a chemical process called the Maillard reaction occurs. This non-enzymatic reaction between amino groups and reducing sugars turns the paste a dark reddish-brown or black.

There is also awase miso, which is a mixed variety. This combines different types to balance flavors, such as mixing salty miso with a milder version.

The history of miso in Japan is deep and spans many eras. Some fermented grain and fish sauces existed during the Jōmon period, from 14,000 to 300 BC. It is believed that fermented soy foods arrived with Buddhism in the sixth century AD. By the Nara period, between 710 and 794, the term for the food began to evolve toward the word "miso." During the Kamakura period, a standard meal included rice, dried fish, vegetables, and miso. In the Muromachi era, Buddhist monks discovered that grinding soybeans into a paste created new ways to flavor food. During the Sengoku period, miso was even used as a military provision.

Flavor profiles are highly specific to different Japanese regions. In the eastern Kantō region, including Tokyo, darker brownish misos are popular. In the western Kansai region, which includes Osaka and Kyoto, lighter misos are preferred. Specific regional specialties exist, such as Hatchō miso from Aichi prefecture. This soybean miso is darker and less sweet than others, requiring a long maturing term. It is often produced using traditional large wooden barrels and heavy stones.

Other unique types include barley miso, which is common in the Kyushu and Shikoku areas. Some versions even use unusual ingredients like buckwheat, hemp seed, or cycad pulp.

The unique taste of miso comes from its complex chemical makeup. The breakdown of soybean protein through proteolysis produces amino acids. These amino acids create an umami taste, which is a savory sensation. While some ingredients like MSG provide a one-dimensional umami, miso's flavor is multidimensional. This is due to the many different fermentation products and amino acids created by the microorganisms. Specific compounds, such as furanone compounds like HEMF, contribute to its sweet aroma. These chemical reactions ensure that every batch has a distinct sensory profile.

Miso is a versatile ingredient used in many modern and traditional dishes. It can be used to flavor ramen noodles or as a base for dipping sauces.

One example is Nasu dengaku, where miso is used as a sauce for eggplant.

Because miso is a "living food," it contains beneficial microorganisms like Tetragenococcus halophilus. To keep these microbes active, it is often best to add miso to soup just before removing it from the heat. This prevents overcooking the living components of the seasoning.
