| Item Identity | Representative scientific name Lablab purpureus (L.) Sweet, edible legume of the Fabaceae family |
| Key role | Specialty legumes that allow young pods, immature seeds, and mature dried seeds to be utilized as different products |
| Harvesting principle | Separating young pods for vegetables and mature harvests for dried seeds |
| Product separation | Fresh Pod · Fresh Seed · Dry Seed · Cleaned Seed · Flour · Processed Ingredient |
| Separation of similar items | Species Entity separation of black mung beans, cowpeas, lima beans, kidney beans, etc. |
| Domestic statistics | The latest government-approved statistics on the nationwide exclusive cultivation area and production volume of *Spanish kaempferi* could not be confirmed in this verification → To be entered after verification of official raw data. |
| safety | Since the anti-nutritional components of seeds need to be examined depending on the variety, stage of maturity, and processing method, raw consumption and insufficient heating are not generalized. |
| Supply and demand risk | Insufficient assessment of domestic production scale, mixed varieties, mixed edible stages, lack of producer and buyer specifications |
| Industry Opportunities | Regionally specialized legumes, young pod vegetables, dried seeds, powder/mixed grain ingredients, ingredients for dining-out/ethnic foods |
| Operating Principles | You must separate Species–Variety–Harvest Stage–Product Form–Processing–Buyer. |

Kew recognizes Lablab purpureus as an Accepted Species and describes it as a crop with edible, feed, and environmental uses. The Rural Development Administration also designates the Korean black soybean as Lablab purpureus. ( Plants of the World Online )
USDA plant introduction records confirm the use of young pods and immature seeds of the hyacinth bean as vegetables, and dried seeds have also been used for cooking. ( ARS Grin )

The hyacinth bean can grow as an annual or short-lived perennial, and due to its ability to remain green even during droughts in tropical regions, it is utilized as fodder, cover crop, and green manure. However, standard sowing times, cultivation periods, and yields for domestic edible production are not applied arbitrarily without official data. ( Plants of the World Online )
For edible seeds, appropriate pretreatment and heating processes are important, considering anti-nutritional components based on variety and maturity. Since relevant FAO legume data also addresses the anti-nutritional factors of Lablab seeds, raw seeds are not registered as products suitable for immediate consumption. ( Open Knowledge )

Since the hyacinth bean is used internationally under various trade names such as Hyacinth bean and Lablab bean, and its historical scientific name, *Dolichos lablab*, has also been commonly used, both the Scientific Name and Commodity Synonym must be managed together in trade searches.
