What Is Tofu Made Of: Soybeans – The Main Ingredient of Tofu
Soybeans, the main ingredient in tofu, are highly nutritious and offer numerous potential benefitsThey contain essential amino acids, vitamins, and minerals, and have been consumed for centuries in various forms, including fresh tofu.
Soybeans provide the base for tofu, acting as a blank canvas that absorbs flavors and takes on different textures, from the creamy consistency of soft silken tofu to the firmer tofu that holds up well in stir fry dishes. The soybean curd created from the coagulation process is pressed into a block of tofu, which can then be sliced, diced, or used whole in a variety of dishes.
To make tofu, first, soak soybeans, then grind them into a paste. Next, filter the paste to separate the solids (okara) from the liquid (soymilk) to create the foundation of tofu.
Coagulants – The Secret Ingredient in Tofu Production
The next step in the tofu production process involves adding coagulants to the fresh soy milk. Coagulants such as nigari (magnesium chloride) and gypsum (calcium sulphate) are added to the soy milk to cause it to solidify. The amount of water in the tofu is determined by the type of coagulant and the pressing process, with firmer tofu containing less moisture. This step is crucial for achieving the desired texture of tofu, whether you’re making homemade tofu or purchasing store-bought tofu.
The Production Process of Tofu: The Process of Making Soymilk
The production of tofu begins with soaking soybeans in water for several hours or overnight, then grinding them into a fine paste. This paste is mixed with water and filtered to separate the solids (okara) from the liquid, resulting in fresh soy milk. This fresh soy milk forms the foundation for tofu.
The Process of Coagulation
Next, the soy milk is heated, and coagulants are added. This causes the soy milk to curdle, forming curds and whey. The curds are then pressed to remove excess liquid and shape the tofu into blocks.
The Process of Pressing and Packaging
The final step in the tofu production process is pressing the curds to remove any remaining whey and form a block of tofu. This step is essential for achieving the right moisture content and texture of tofu. The tofu is then cooled, packaged, and sold in grocery stores or tofu shops.

The Process of Making Tofu: What Is Tofu Made Of
The process of making tofu begins with soaking, grinding, and boiling soybeans. Cook soybeans until soft, then press them into a thin paste. Pour the paste into molds and let it set. Cut the tofu into cubes or rectangles and use as desired. It can be served in many creative ways. From vegan salads to desserts!
| Step in Tofu Making Process | Description |
|---|---|
| 1. Soybean Selection and Soaking | High-quality soybeans are selected and soaked in water for several hours or overnight. This softens the beans and prepares them for grinding. |
| 2. Grinding and Boiling Soybeans | The soaked soybeans are ground into a fine paste using a blender or mill. The ground soybeans are then cooked in water to create soy milk. |
| 3. Coagulating and Curdling Soy Milk | Coagulants such as nigari (magnesium chloride), gypsum (calcium sulfate), or calcium sulfate are added to the soy milk. This coagulates the proteins, causing the soy milk to curdle into solid curds and liquid whey. |
| 4. Pressing and Shaping the Tofu | The curdled soy milk is transferred to a tofu mold lined with cheesecloth or tofu press. Pressure is applied to remove excess whey and shape the curds into a solid block. The tofu is left to set and firm up for a specified time. |
| 5. Cooling and Packaging | After the tofu has set, it is carefully removed from the mold and cooled. It may be rinsed in cold water to improve texture and remove any residual flavors. The tofu is then packaged and ready for consumption or further processing. |

Interesting Facts About Tofu
Tofu is naturally low in calories, carbohydrates, and fat, and is a great source of protein, fiber, and essential minerals like magnesium, phosphorus, iron, and calcium. It doesn’t contain any cholesterol or saturated fats, making it a heart-healthy choice. In recent years, tofu has become increasingly popular as a protein-rich food in vegan diets and among those seeking to reduce their intake of animal products.
How does Tofu compare against other plant-based proteins?
Tofu is a staple in many vegan diets and is often compared to other plant-based protein sources like tempeh, seitan, and Textured Vegetable Protein (TVP). When evaluating tofu against these alternatives, several factors come into play, including protein content, texture, nutritional benefits, and potential adverse effects. Tofu is a versatile plant-based protein.
Protein Content and Nutritional Value
Tofu, particularly extra firm tofu, is a protein-rich food, providing around 8 grams of protein per 100 grams. This makes it an excellent source of protein for those looking to incorporate more soy foods into their diet.
Tempeh, another soy-based food, offers an even higher protein content, with approximately 19 grams per 100 grams. Seitan, made from wheat gluten, boasts an impressive 25 grams of protein per 100 grams but lacks the complete protein profile that tofu provides, meaning it must be paired with other foods to ensure all essential amino acids are consumed. The beauty of tofu is that you can easily find it in the grocery store and it doesn’t take a lot of work to prepare.
| Plant-Based Protein | Grams of Protein (per 100g) | Notes |
|---|---|---|
| Tofu | 8g | High in calcium, versatile texture |
| Tempeh | 19g | Rich in fiber, fermented soy product |
| Seitan | 25g | High in protein, wheat-based |
| TVP | 12g | Low fat, often used in meat substitutes |
Nutritional Benefits and Concerns
Tofu is not only valued for its protein but also for its beneficial effects on health, such as potentially reducing the risk of bone loss and lowering cholesterol levels. According to a recent review by the European Food Safety Authority, soy foods like tofu may help lower the risk of heart disease, supported by the presence of mg of soy isoflavones. However, like other soy products, tofu contains trypsin inhibitors, which can interfere with protein digestion, though these are generally deactivated during cooking.
On the other hand, animal milk and other animal protein sources lack some of the health benefits associated with soy foods and come with potential adverse effects like higher cholesterol and an increased cancer risk. American Institute studies have shown that plant-based diets rich in soy foods may offer protection against certain types of cancer, including breast and prostate cancer, contributing to overall better health outcomes compared to diets high in animal protein.
