Tofu (豆腐)

Tofu (豆腐)

Tofu is one of the most essential ingredients in Japanese food culture. There are so many different types and popular dishes that are made from tofu. Today, let’s find out all about this amazing food – history, health benefits, recipes, stores to get to know why Japanese are so in love with it!

What is Tofu?

Tofu (豆腐) is processed soybean foods that has smooth texture. The main types of tofu in Japan are firm (momen tofu), silken (kinugoshi tofu), juten tofu and yosedofu.

The name of it “豆腐” comes from China, the birthplace of it with the meaning of “bean curd”/ “bean ferment”. The earliest documented use of the word “tofu” in the English language is James Flint’s letter to scientist Benjamin Franklin on how Chinese converted soybeans into bean curd.

History

Tofu (豆腐)

Today, tofu is popular all over the world but do you know where does it come from? It is said that it originated from China more than 2000 years ago during the Han dynasty. Liu An, the grandson of the first emperor was the first person to make it.

By the way, how did it enter Japan? During the Nara period, envoys to the Tang dynasty had special missions as cultural exchange between the two countries. These envoys had a strong impact on nowaday Japanese society not only in culture, technology but also the food. Buddhism was also introduced to Japan during this time and there is a theory that the monks brought along tofu with it as one of the ingredients used in temples. In latter half of the Heian period, the word “tofu” actually appears in literature for the first time.

In the Kamakura period, Zen Buddhism was introduced from China. People who follows Zen Buddhism, as part of their training, avoid eating meat and fish and eat dishes made entirely from plant-based foods. This is the so-called shojin cuisine. For this reason, tofu has become a really important ingredient in Shojin cuisine and used to be foods mainly for monks and samurai.

It was not until the Edo period that it became popular among the common. From this period, tofu shops appeared and there are many stores that still opens up until now. As a refreshing and easy to eat dish, it was really popular among the common and in 1782,  “Tofu Hyakuchin”, which introduced 100 kinds of dishes, was published and became a hot topic. That is the reason why it was widely used as food ingredient during the Edo period.

Juten Tofu (充填豆腐)

You can find this type in package type. It has the same smooth texture as silken tofu but juten tofu tends to keep longer than other types as the soy milk is sterillized while processing. It is also packaged without water because the package is vacuum-sealed.

Processed tofu products

  • Yakidofu: made by draining firm tofu and grilling it over charcoal or oven. It does not crumble easily so it is often used for sukiyaki, simmered dishes, and dengaku.
  • Namaage/ Atsuage tofu: to make this type, drain firm tofu and then fry at a high temperature. It also has a name: atsuage tofu, which is another name for deep-fried tofu. 
  • Aburaage: thin-fried tofu
  • Ganmodoki: Japanese tofu patties with tofu as a base, mix with vegetables, musrooms and then pan fry.

Others

  • Tonyu: soymilk. This is not really a type of bean curd but a type of liquid produced while making it.
  • Okara: the leftover when squeeze the mixture to make soymilk. Okara contains a considerable amount of protein and fat, as well as dietary fiber and micronutrients.
  • Yuba: dried tofu skin. When heating the soymilk, a film forms on the surface and it is pulled up with a bamboo skewer to produce “raw yuba,” which is used for cooking. In terms of nutrition, yuba is rich in protein and oil, and you can keep it as one type of dried food.

Health info

Health benefits of tofu

Tofu is attracting attention as a “functional food” that maintains and promotes health by regulating the body, as well as providing basic nutrients such as protein and lipids for the body. Let’s find out what is inside this dish:

  • Protein linoleic acid: lowering blood pressure and cholesterol
  • Lecithin/β-conglycinin: against fat metabolism and fatty liver 
  • Lecithin/Choline: Improves memory and prevents aging and blurring of the brain
  • Saponin: against geriatric diseases and anti-aging by suppressing active oxygen
  • Calcium: good for bones and teeth
  • Vitamins: contains vitamin E, vitamin B1, vitamin B2, and niacin. E has the effect of improving blood circulation, improve skin beautiful, stiff shoulders, and lower back pain, etc.

Okara’s nutritions

After the soybeans are ground and boiled, the leftover after squeezing out the soymilk is okara. Therefore, most of the fiber from soybean skins and germs has migrated to okara. Dietary fiber improves bowel movements and prevents harmful substances from staying in the intestines, and is also effective in preventing high cholesterol and obesity. Okara contains not only fiber but also protein and lipids, although not as much as tofu. Therefore, okara is also rich in nutrition and can be used as a functional food.
