Judgment axis | Key judgment |
| Item Identity | A vegetable of the Brassica oleracea Gongylodes Group whose main product is its enlarged above-ground stems. |
| Key role | Raw food, salad, school meals, dining out, fresh-cut, pickled, HMR, frozen, dried ingredients |
| Harvesting principle | Evaluate variety, thickened stem diameter, weight, bark color, hardness, lignification, leaf condition, and Buyer's intended use together. |
| Product separation | Separate leafy raw, leaf removed, washed, peeled, Whole, Slice, Stick, Julienne, Dice, Fresh-cut, Pickled, Frozen, and Dried. |
| Separation of similar items | Distinguishing between turnips, cabbage, broccoli, kale, etc., and Species or Cultivar Groups/Edible Organisms |
| Domestic statistics | Nationwide cultivation area and production volume of Kohlrabi alone: To be entered after verification of official raw data. |
| Color distinction | Kew explained that white, green, and purple swollen stems exist in the Gongylodes Group. ( Plants of the World Online ) |
| Quality Risk | Hypertrophy, lignification, increased fibrousness, cracking, deformity, internal cavity, epidermal damage, moisture loss |
| Production Risk | High temperature, low temperature, sowing time, planting density, moisture imbalance, drainage, and cabbage diseases |
| Fresh-cut risk | Peeling yield, cutting yield, browning, moisture loss, microorganisms, refrigerated distribution |
| Operating Principles | Seed–Production–Swollen Stem Lot–Wash/Peel/Cut–Buyer RFQ |
| Final goal | Actual supply capacity evaluated based on size, hardness, fresh-cut yield, and buyer availability, rather than production kg. |
