What Does Tofu Mean: Unveiling Its Origins and Uses

What Is Tofu

Bean Curd

Tofu, often referred to as bean curd, is a versatile food product made from soybeans. It is considered a nutrient-rich source of protein, containing all the essential amino acids the human body needs, and is additionally loaded with fiber, vitamins, and minerals¹.

Soy Product

Traditional

Traditionally, tofu has been a staple in the cuisines of China, Japan, Korea, and Southeast Asia². Its origins date back to the Han dynasty (206 BCE – 220 CE) and have made it an important source of protein in these cultures’ culinary practices².

Some popular traditional tofu dishes include:

• Mapo tofu: a spicy Chinese dish with tofu and minced meat in a Sichuan pepper sauce.
• Miso soup: a Japanese soup featuring tofu and seaweed in a savory miso broth.
• Kimchi jjigae: a Korean stew with tofu, kimchi, and other vegetables in a flavorful broth.

Tofu’s appeal lies in its ability to absorb flavors from spices, sauces, and marinades, making it an excellent ingredient in various dishes³. Given its nutritional benefits and versatility, tofu’s popularity continues to grow as a choice for health-conscious individuals and those seeking plant-based protein options.

Process of Making Tofu

Soy Milk

The process of making tofu begins with the preparation of soy milk. Soy milk is derived from dried soybeans, which are soaked in water, crushed, and boiled to release their nutrients efficiently. To begin, measure out the desired quantity of dried soybeans and allow them to soak overnight. Once the soybeans have absorbed adequate water, they are crushed into a fine pulp or paste. The mixture is then boiled and eventually strained to separate the liquid soy milk from the solid pulp, known as okara.

Coagulants

Once the soy milk is prepared, coagulants are added to the mixture to help separate the curds and whey. Salt coagulants, such as calcium and magnesium chlorides and sulfates, are essential for this step. These coagulants cause the proteins within the soy milk to curdle, resulting in the formation of tofu curds.

Nigari

Nigari is another coagulant that is popularly used for making tofu. It’s a seawater-derived liquid that’s rich in magnesium chloride. When nigari is added to the soy milk, it causes the curds to form more quickly and efficiently than other coagulants. This substance is particularly suitable for creating softer, silken tofu.

Calcium

Calcium sulfate, also known as gypsum, is another common coagulant used in the tofu-making process. This coagulant introduces a higher calcium content to the final tofu product, making it an excellent option for those seeking a calcium-enriched, plant-based protein. Gypsum, when used as a coagulant, produces a softer silken tofu compared to nigari.

The Final Steps

After the coagulants have been added and the curds have formed, the next step is to press the tofu curds. Tofu is often pressed with a specialized tofu mold or a homemade rig lined with layers of cheesecloth. The mold or rig lets the whey drain off while maintaining the shape of the tofu. Weights are placed on the mold to compact the curds, and the pressing time varies depending on the desired firmness of the final product. The resulting block can be used in numerous dishes, enjoyed plain or seasoned to taste, depending on the preference of the individual consuming it.
