In this article, we will delve into the world of bean curd, exploring its origins, production process, types, and uses in traditional Chinese cooking.
A Brief History of Bean Curd
The origins of bean curd can be traced back to the Han Dynasty (206 BCE – 220 CE), where it was first mentioned in Chinese literature. According to legend, bean curd was discovered by a Chinese cook named Liu An, who accidentally curdled soy milk with a type of seaweed called nagari. The resulting product was a soft, white, and nutritious food that quickly gained popularity throughout China.
Over time, bean curd spread throughout Asia, with different countries developing their unique production methods and recipes. In China, bean curd became an integral part of the cuisine, particularly in the southern regions, where it was used in a variety of dishes, from soups to stir-fries.
The Production Process of Bean Curd
Bean curd is made from soybeans, water, and a coagulant, typically calcium sulfate or magnesium chloride. The production process involves several steps:
Soaking and Grinding the Soybeans
Soybeans are first soaked in water to rehydrate them, then ground into a fine paste using a stone grinder or a modern machine.
Mixing with Water and Coagulant
The soybean paste is then mixed with water and a coagulant, which causes the mixture to curdle.
Pressing and Shaping
The curdled mixture is then pressed into a block shape using a cheesecloth or a tofu mold. The pressure removes excess liquid, resulting in a firm and compact block of bean curd.

What is bean curd, and how is it made?
Bean curd, also known as tofu, is a traditional Chinese food made from soybeans.

The production of bean curd involves several steps, including soaking and grinding the soybeans, mixing the soy milk with a coagulant, and then curdling and pressing the mixture. The resulting bean curd can range in texture from soft and silky to firm and chewy, depending on the type of coagulant used and the pressure applied during the pressing process. Bean curd is a versatile ingredient that can be used in a wide variety of dishes, from soups and stir-fries to salads and desserts.
