Market
Conventional dried persimmon in Vietnam is a niche processed-fruit product closely associated with Da Lat (Lam Dong Province), where “wind-hung” persimmon (hồng treo gió) production has developed as a value-added outlet during the local persimmon season. Production is seasonal, with Da Lat persimmons commonly harvested from late August through November and then processed through peeling and controlled drying/hanging workflows. Domestic demand is strongly tied to tourism, gifting, and specialty dried-fruit consumption, with distribution extending to major cities and online channels. For any export ambitions, the key constraints are consistent mold control, accurate labeling, and compliance with Vietnam’s food additive rules (where applicable) and importing-market requirements.
Market RoleNiche domestic specialty producer with limited export footprint
Domestic RoleSeasonal specialty processed fruit product for gifting, tourism, and urban retail
Market Growth
SeasonalitySeasonal raw fruit supply in late Aug–Nov drives the main annual production window for wind-hung dried persimmon in Da Lat.
Specification
Primary VarietyDa Lat persimmon types used for wind-hung drying (commonly referenced as hồng trứng)
Physical Attributes- Fully peeled fruit with intact stem retained for hanging
- Chewy/dry outer layer with honeyed interior when properly matured
- Surface defect control is critical: bruising, tearing, or deep cuts during peeling can increase spoilage risk
Compositional Metrics- Moisture control (and related water activity) is a key acceptance parameter because excess moisture increases mold risk during hanging and storage
Grades- Mold-free surface and clean aroma
- Uniform dryness/texture and consistent size within a pack
- Clean packaging integrity (no seal failures or moisture ingress signs)
Packaging- Vacuum-sealed retail packs and/or boxed vacuum-packed units to reduce moisture uptake and contamination risk
Supply Chain
Value Chain- Orchard harvest (Da Lat area) → selection → washing/surface sanitation → peeling (retain stem) → short pre-drying in low-temperature oven (some producers) → hanging/air-drying in sheltered greenhouse space with ventilation → routine inspection for mold/defects → vacuum packaging → domestic distribution via retail/tourism/e-commerce
Temperature- Not a cold-chain product, but cool, dry storage is important to prevent moisture uptake and mold growth after drying
- Some production workflows use low-temperature pre-drying (reported around 50–60°C for several hours) before hanging
Atmosphere Control- Ventilation and humidity control are critical during the hanging period; fans and insect exclusion measures are commonly used in described Da Lat facilities
Shelf Life- Shelf-life is highly sensitive to moisture ingress and seal integrity; vacuum packaging is used to extend stability and reduce contamination risk

Transport ModeMultimodal
Risks
Food Safety HighExport shipments of dried persimmon from Vietnam face a high risk of border rejection or delisting if mold contamination occurs or if labeling/testing does not align with the actual product (e.g., undeclared or out-of-limit preservatives such as sulfites where used, or failure to control moisture leading to spoilage).Implement batch-level moisture targets and mold monitoring during hanging/drying, use validated sanitation steps, run pre-shipment lab tests aligned to target-market requirements (including sulfites if relevant), and enforce label–spec–COA consistency.
Regulatory Compliance MediumVietnam’s food safety implementing framework has recent updates (including a 2026 implementing decree effective mid-April 2026), creating a moving compliance baseline for declarations, traceability expectations, and enforcement coordination.Maintain a regulatory change log, confirm current Vietnam MOH/VFA requirements for additives and food safety documentation, and align internal SOPs to the latest effective legal instruments.
Climate MediumHumidity and weather variability during the Da Lat persimmon season can increase mold and spoilage risk during the multi-week hanging/drying period, reducing yield and creating batch inconsistency.Use sheltered/greenhouse hanging spaces, active ventilation/dehumidification as needed, and tighten incoming fruit selection to reduce damage-related spoilage pathways.
Logistics MediumWhile dried persimmon is less perishable than fresh fruit, small-batch shipments are exposed to freight-rate volatility and handling damage; packaging failures can lead to moisture pickup and quality loss in transit.Use robust vacuum packaging with secondary moisture barriers, define container/handling specs with logistics partners, and plan consolidated shipments to reduce per-unit freight exposure.
Sustainability- Orchard input management (pesticide stewardship) affects residue risk for the raw fruit entering drying
- Energy use and efficiency in pre-drying/controlled drying steps (where used) can affect cost and footprint
- Food loss risk from spoilage/mold during humid weather periods increases waste and rework
Labor & Social- Seasonal labor intensity in peeling/handling steps increases the importance of hygiene training and documented worker practices in export-facing facilities
- Visitor-facing “experience” production sites (tourism-linked) increase the need for controlled access, PPE, and cross-contamination prevention
Standards- HACCP (Codex-aligned) food safety management approaches are commonly expected by many importers and modern retail programs
FAQ
When is the main production season for Da Lat wind-hung dried persimmon in Vietnam?It is closely tied to the Da Lat persimmon harvest season, commonly described as running from late August through November, after which fruit is processed and hung/dried over subsequent weeks.
What is a typical processing flow for “hồng treo gió” (wind-hung dried persimmon) in Da Lat?Commonly described steps include selecting harvested fruit, washing/cleaning, peeling while keeping the stem for hanging, optional short low-temperature pre-drying, then hanging the fruit in a ventilated sheltered area for around a few weeks with routine checks to prevent mold, followed by vacuum packaging.
If a producer uses preservatives in dried persimmon, what rule matters most in Vietnam?Any additive use must comply with Vietnam Ministry of Health rules on permitted food additives and maximum use levels (and must be correctly declared on the label where applicable); Vietnam has also aligned parts of its additive framework with Codex GSFA references through recent circular amendments.
