The Tofu Tale: How 2,000 Years of History Shaped the Future

Tofu appears simple: soybeans, water and a coagulant transformed into a pale block. Behind it lies a remarkable history of craft, migration and reinvention.

Over centuries, tofu spread from China across East and Southeast Asia through migration and trade, developing into regional forms. Today, this ancient food is increasingly relevant as people seek sustainable ways to eat.

Its story is not a straight line—and it does not begin with one proven inventor.

Where Did Tofu Begin?

Tofu originated in China, but exactly when and how remains uncertain.

The best-known legend credits Liu An, a Han-dynasty prince who lived in the second century BCE. Later traditions portray him developing tofu while pursuing nourishment, medicine or immortality. Yet no surviving record from his lifetime confirms the story.

Other theories suggest that soy milk was accidentally curdled by mineral-rich sea salt, or that Chinese makers adapted dairy-curdling knowledge through contact with pastoral peoples. Both are plausible; neither is proven.

A second-century tomb relief from Dahuting in Henan has also been interpreted as showing tofu production, although scholars disagree about what it depicts.

Clearer written evidence appears much later. Tao Gu’s tenth-century Qing Yilu mentions tofu as an economical food associated with people unable to afford mutton. Tofu may therefore approach 2,000 years of history, but its precise beginnings remain partly beyond the written record.

The Ingenious Technology Behind Tofu

Whatever its origin, tofu reflects deep practical knowledge.

Makers soaked soybeans, ground them with water and heated the slurry. After separating the soy milk from the fibrous pulp, now commonly called okara, they added a coagulant. Mineral salts or acids encouraged the heated soy proteins to form a network that held water. The curds could then be drained and pressed to different degrees.

Soybean variety, water, coagulant, temperature, timing and pressure all influenced flavour, yield and texture. Some tofu remained delicate enough to eat with a spoon; some became firm enough to fry or braise.

Makers froze, dried, smoked and fermented tofu. They also lifted the thin skins formed on heated soy milk to produce yuba. Tofu traditions extended far beyond one white block.

How Tofu Travelled Through Asia

Tofu spread through migration, commerce, religious exchange and the movement of culinary knowledge. Its routes cannot be reduced to one journey or credited entirely to Buddhist monks.

In Japan, the earliest known written reference dates to 1183, when tofu was recorded in connection with an offering at Kasuga Shrine in Nara. Buddhist vegetarian cookery later helped demonstrate how precisely tofu could be prepared and valued on its own terms.

By the Edo period, tofu was part of everyday Japanese food culture. The popular 1782 cookbook Tōfu Hyakuchin presented 100 preparations, showing that experimentation with tofu flourished centuries before today’s plant-based movement.

Korea developed traditions around dubu, from delicate fresh curds to firm tofu and soft-tofu stews. Across Vietnam, Indonesia, Malaysia, Singapore, Thailand and the Philippines, tofu entered local soups, curries, braises, salads and street foods.

These cuisines did not simply reproduce one Chinese original. Each community made tofu locally meaningful.

From Migrant Food to Global Ingredient

European descriptions of tofu appeared by the seventeenth century. In 1770, merchant James Flint sent Benjamin Franklin an explanation of how Chinese cooks made “towfu”. Franklin forwarded the account and soybean seeds to botanist John Bartram.

Tofu’s durable presence outside Asia, however, was built principally by Asian migrants. Chinese and Japanese communities established tofu shops in North America, Australia and elsewhere, preserving both a familiar food and the knowledge needed to produce it.

During the twentieth century, refrigeration, sealed packaging and industrial manufacturing carried tofu beyond neighbourhood shops. From the 1970s, vegetarian and natural-food movements introduced it to wider Western audiences.

Greater visibility also brought misunderstanding. Removed from the cuisines that had refined it, tofu was frequently presented as a bland block expected to behave like meat—a narrow framing that obscured its much older culinary identity.

More Than a Meat Substitute

Historically, tofu’s role was much broader.

It supported meatless eating, particularly within Buddhist traditions, but also appeared alongside fish, meat, eggs, grains and vegetables. It supplied protein, extended limited ingredients and created contrasts of temperature and texture.

Its mild flavour was not a defect waiting to be hidden. Fresh tofu could be appreciated for its subtle sweetness and tenderness, while preserved forms offered different characters. Cooks steamed, simmered, seared, stuffed, fermented and fried it.

Seeing tofu only as imitation meat obscures much of what generations of makers and cooks created.

An Ancient Food Facing Forward

Traditional tofu shops now coexist with controlled modern production. Experienced makers still judge curds through sight and touch, while manufacturers use precise heating, coagulation and hygienic packaging to achieve consistency and safety at scale.

Researchers and producers are exploring improved soybean varieties, longer shelf life, efficient processing and valuable uses for okara. These developments continue a principle that has shaped tofu throughout its history: drawing more nourishment and possibility from the soybean.

Tofu cannot solve every problem in the food system, and responsible farming and production still matter. Nevertheless, soy foods generally require substantially less land and generate fewer greenhouse-gas emissions than many animal proteins. Choosing tofu for some meals can support a gradual shift towards a more plant-rich food culture without demanding all-or-nothing change.

Final Takeaway

Tofu endured because it never stood still.

From uncertain beginnings in China to temple kitchens, family tables, street stalls, migrant businesses and modern factories, every community added something to its story. Its history shows that meaningful food change is rarely created by one inventor or dramatic moment. It grows through shared knowledge, local adaptation and countless everyday meals.

Tofu’s future will be shaped in the same way: by respecting where it came from, discovering what it can become and giving this quiet ingredient a meaningful place at the table.
