What is Fish Tofu and How is it Made?
Fish tofu, also known as fish cake or fish ball, is a type of processed seafood product made from fish surimi, a paste-like substance derived from pulverized fish flesh. The production process of fish tofu involves several steps, including the selection of raw materials, grinding, mixing with other ingredients, and shaping into the desired form. The fish surimi is typically made from low-cost fish species such as pollock, cod, or tilapia, which are abundant and have a mild flavor.
The mixture of fish surimi and other additives, such as starch, protein, and flavorings, is then shaped into various forms, including cubes, slices, or balls, depending on the intended use. The fish tofu is then cooked, usually by steaming or deep-frying, to create a firm and chewy texture. The resulting product has a neutral flavor and a soft, spongy texture, making it a versatile ingredient for various dishes, including soups, stews, and stir-fries. Fish tofu is also a popular ingredient in many Asian cuisines, particularly in Chinese, Japanese, and Korean cooking, where it is often used to add protein and texture to meals.

It’s also important for consumers to be aware of any food allergies or sensitivities they may have, and to take steps to avoid exposure to allergens or contaminants that can cause adverse reactions. By being informed and taking precautions, consumers can enjoy fish tofu safely and responsibly.
