Key judgment

Item IdentityCucurbitaceae fruits and vegetables that utilize the large fruits of *Benincasa hispida* of the family Cucurbitaceae.
Key roleFruit pulp for cooking, candied fruit, pickled vegetables, preserved foods, soups, processed foods, and pre-processed ingredients
Harvesting principleSeparation of young fruit, edible mature fruit, mature storage fruit with surface wax, and seed fruit according to use
Product separationPassing, peeling, cutting, seed removal, candied fruit, pickling, freezing, puree, and finished processed products are managed as separate products.
Separation of similar itemsPlant Entity separate from Cucurbitaceae plants such as bitter melon, gourd, and loofah.
Domestic statisticsOfficial national statistics on nationwide winter melon exclusive cultivation area and production volume: To be entered after verification of official raw data.
Basis for domestic useConfirmation of winter melon maturation characteristics and uses for candied fruit and pickles in Gangwon Special Self-Governing Province agricultural technical data
Supply and demand riskLow market awareness, handling of large fruits, harvesting labor, lack of standard specifications, lack of connection with processing facilities, and unclear buyer demand
Operating PrinciplesSeed–Plant–Fruit–Maturity–Harvest Lot–Cut/Processing Lot–Buyer RFQ Connection
Final goalCreating stable contractual demand linked to peeling, cutting, and flesh yield requirements of food processing companies, rather than simply selling large fruits.

5. Korea Market & Demand Structure

Korean production structure

Nationwide winter melon cultivation area:  To be entered after verification of official raw data
Nationwide winter melon production volume: To be entered after verification of official raw data

Because it is difficult to reliably calculate the latest nationwide production volume and cultivation area of ​​Dong-A solely based on currently available official data, regional exhibitions, research, and cultivation cases are not expanded into national production statistics.

The National Institute of Horticultural and Special Crops Science and local agricultural institutions have consistently treated winter melon as a type of cucurbit vegetable. In the selection of cucurbit vegetable champions, in which the Rural Development Administration and the Chungbuk Agricultural Research and Extension Services participated, gourds, winter melons, and bitter melons were managed as a separate crop group. ( Rural Development Administration )

Trade Management

Since the tariff classification of Dong-a may vary depending on whether it is fresh/refrigerated, frozen, cut, pickled, or prepared, a specific HS code is not arbitrarily determined based solely on the product name Dong-a.

Data from Gangwon Special Self-Governing Province presents Dongajeonggwa and Dongajangajji as representative processed winter melon products . ( Gangwon-do Ares )

In addition, a study analyzing the quality characteristics of bread with added heat-treated winter melon was published in the Korean Journal of Food Science and Technology in 2003, indicating that bread product research has been conducted in actual academic practice. ( KCI )
