Judgment axis | detail |
| Item Identity | Sweet potatoes are root crops that utilize the enlarged tuberous roots of the sweet potato (*Ipomoea batatas*) for food and processing. |
| Basic registration range | Manages raw sweet potatoes, washed and sorted sweet potatoes, variety-specific raw materials such as chestnut and pumpkin sweet potatoes, roasted and steamed sweet potatoes, cut and frozen products, and dried sweet potato slices, chips, powder, and starch raw materials. |
| Core separation | For edible, processing, seedling production, and feed use, as well as varieties, harvest time, storage conditions, and processing stages, are separated into Product and Lot units. |
| Purchase criteria | It is a report on variety, production location, harvest year, size and shape, skin damage and spoilage, sugar content and dry matter content, meat color, storage history, texture after heating, and safety. |
| Major risks | These include low-temperature damage, spoilage or weight loss during storage, mismatch between variety and intended use, inclusion of damaged raw materials, variations in sweetness or texture after heating, and discontinuity in the history of pretreatment or drying processes. |
| Industry Opportunities | This involves variety-specific small packaging such as chestnut sweet potatoes and pumpkin sweet potatoes, pre-processing for school and restaurant use, roasted sweet potatoes and HMR, dried snacks, chips, and powder materials, as well as RFQ matching between producers, processors, and private brand buyers. |
| Operational direction | It connects production, harvesting, curing, storage, sorting, processability testing, RFQ, and delivery/repurchase on a Lot basis. |

Kew Plants of the World Online presents the scientific name for sweet potato as Ipomoea batatas (L.) Lam. Since the edible part of the sweet potato is the tuberous root rather than the underground stem like the potato, the storage, processing, and quality dataset is not integrated with that of the potato.

Both sweet potatoes and potatoes are underground starchy agricultural products, but potatoes are tubers of the Solanaceae family, while sweet potatoes are tubers of the Convolvulaceae family. In particular, they are managed as separate items due to differences in post-harvest curing, risks of low-temperature storage, sweetness and texture after heating, and variety-specific distribution structures.
