About Black soybean

Black soybean is a soybean variety with a dark, usually black seed coat and a pale interior. It is eaten as a cooked whole legume in soups, stews, grain and bean dishes, and traditional preparations that use its dark colour. The beans may be sold dried, soaked, boiled, canned, or otherwise prepared for storage.

Cooked black soybeans have a mild, nutty legume flavour and a tender but substantial texture when fully cooked. The seed coat contributes colour to the cooking liquid and finished dish. Fermented forms are distinct processed foods and should not be treated as interchangeable with plain cooked beans.

Black soybeans are sold as dry beans and in prepared forms, including soaked and cooked or canned beans. Soaking and boiling hydrate and soften the seeds, while draining can remove some coloured cooking liquid. Fermentation changes the ingredient into a distinct processed form rather than simply altering plain cooked beans.

Per 100 g edible portion. Values use MEXT 2023 with March 2026 corrections; the English food name is matched by food code from the official English edition. Carbohydrate is total carbohydrate by difference. Values in parentheses in the source are estimates reported by MEXT. This reference does not cover other preparations or brands.

Portions & preparation

Confirm that the ingredient is the black-seeded soybean variety and match dry, boiled, canned, sprouted, or fermented form. Drain canned beans when appropriate, and separate added oil, salt, sauce, or other ingredients from the bean portion. Cooking changes the reference form and edible amount.

Compare the right form: Reference must match black soybean variety and the stated dry, cooked, canned, sprouted, or fermented edible form.

Diet considerations

Black soybeans are plant-derived legumes and are soy ingredients. Plain beans suit plant-based patterns, but meat, dairy, broth, sauces, or cereal ingredients in prepared dishes can change compatibility. Their carbohydrate pattern depends on portion and form; fermented or packaged products require review of the complete recipe.
