Key Differences
Soybeans are a complete source of protein, containing all essential amino acids, whereas tofu is a soy-based product that retains most of these nutritional benefits in a processed form.
Soy is consumed in many forms, including as whole beans, soy milk, and soy sauce, while tofu is specifically the curd made by coagulating soy milk and then pressing the resulting curds into soft white blocks.
In terms of culinary uses, soybeans can be used directly in dishes or processed into various products, whereas tofu is typically used as a meat substitute or a main ingredient in vegetarian and vegan recipes.
Nutritionally, whole soybeans are rich in fiber and various vitamins and minerals, on the other hand, tofu, while still nutritious, has less fiber due to the processing it undergoes.
The production process of soy involves growing and harvesting soybeans, whereas tofu production begins with the creation of soy milk from these beans and then transforming it into tofu through coagulation.
