Key judgment

Item IdentityCitrus × junos' Hybrid Citrus Fruit
Key roleThe industrial share of processed yuzu products—such as jam, tea, juice, peel, puree, sauce, beverage, and private label—is greater than that of fresh fruit.
Harvesting principleEvaluate variety, skin color, aroma, acidity, juice content, and processing purpose together.
Product separationFresh, green, tea, juice, peel, puree, dried, and powder are managed as separate products.
Separation of similar itemsPlant/Product Entity separate from tangerines, lemons, limes, and grapefruits
domestic productionIt is a fruit tree actually cultivated mainly in the southern regions of the country, and representative production areas include Goheung.
Domestic statisticsThe 2025 nationwide yuzu cultivation area and production volume will be entered after verifying the official raw data.
Quality CoreSkin color, aroma, juice content, acidity, Brix, skin integrity, seeds, and lesions
Processing coreSimultaneous utilization of peel/juice as well as pulp, and raw material mass balance
Supply and demand riskWeather, low temperatures, alternate bearing, fruit set, concentrated harvest, processing facility capacity, export demand
Operating PrinciplesOrchard–Harvest Lot–Peel/Juice–Processing Batch–Buyer RFQ
Final goalSupply capacity is assessed based on Buyer Accepted Quantity for green fruit, juice, skin, and finished products rather than total yield.

The Rural Development Administration describes the typical growth cycle of Yuja as sprouting in April, flowering in mid-to-late May, fruit enlargement from June to October, coloring after mid-October, and harvesting in early November. It also explains that natural fruit drop occurs from early June to early July, and that it is necessary to manage marketability and the following year's fruit set through thinning thereafter.

On the Korea Food Safety Information System (KFDA), Yuja is managed as a citrus fruit. Actual safety assessments regarding pesticide residues require verification of the current individual and group standards for the relevant pesticides; in particular, since the peel is directly used for Yuja jam and tea, Peel-use Safety is designated as the core field. ( KFDA )

Since the yuzu industry has a structure where processing accounts for a larger proportion than fresh fruit, the connection between Harvest Quantity → Processing Capacity → Finished Product Quantity is the key to supply chain analysis. Data on Goheung yuzu from the Rural Development Administration also explains the establishment of processing infrastructure and brand development, in addition to the expansion of cultivation area, as factors driving industrial growth.

Since yuzu is a representative fruit that utilizes both the peel and the juice, calculating only the Juice Yield is not appropriate. For yuzu marmalade lots, the Whole Fruit → Peel/Pulp → Seed Removal → Sugar/Other Input → Finished Marmalade Mass Balance is managed separately.

The conversion of food, flavorings, cosmetics, and functional materials is linked to a separate PRP only when the legality of raw materials, pesticide residues, safety, and official research evidence have been confirmed. On Food Safety Korea as well, Yuzu is subject to pesticide residue management for citrus agricultural products. ( Food Safety Korea )
