How many kilos of dragon fruit make 1 kg of freeze-dried dragon fruit?
13–15 kg of whole fresh red dragon fruit, which becomes 8–9 kg of peeled flesh on the tray, makes 1 kg of finished freeze-dried dragon fruit at FruitBuys’ release moisture of ≤4%. That chain is the floor under every honest quote.
A price that implies much less fruit per kilogram is not a better deal; it is a different product, usually wetter, sweeter or dustier than the sample.
Where do the 13–15 kg go?
Follow one kilogram backwards from the carton to the farm gate:
| Stage | Weight | What is removed |
|---|---|---|
| Whole fruit at the facility gate | 13–15 kg | – |
| Peeled, trimmed flesh on the tray | 8–9 kg | Peel (35–40% of the fruit), stem ends, bruised or off-colour flesh |
| Dried product off the tray | about 1.1–1.5 kg | Water: the flesh is about 84–87% water |
| Finished product after sorting | 1 kg at ≤4% moisture | Breakage and fines screened out against the cut tolerance |
Peel is the biggest single loss, and you see it in the field: red dragon fruit carries a thick, leafy skin that goes straight to compost. FruitBuys has it peeled deep and the stem ends trimmed clean, so no tough skin layer or green peel fragment reaches the tray: every piece in your carton is even magenta flesh that melts on the tongue. Water is the second: drying takes the flesh from roughly 85% water to below 4%. The rest is the work that keeps your carton clean, cutting out bruises, screening out dust and rejecting pieces that do not hold their colour.
Why 8–9 kg of flesh, not 6?
On paper, dry matter alone gives 6 to 7.4 kg of flesh per kilogram. No working line hits that number. Pieces crack on the tray, slice edges break, and everything under 3 mm is screened out before it reaches your bag. That is what takes a real line to 8–9 kg.
That gap is where cheap quotes hide. A supplier who prices off the textbook 6:1 has three ways to make the numbers work, and none of them help you:
- Ship more water. Moisture at 6% instead of 4% puts about 230 kg of extra water into a 40 ft HC load, bought at freeze-dried prices. See the moisture and water activity limits to write into your contract.
- Ship the fines. Dust and broken pieces stay in the carton instead of the reject bin. In a white granola, that shows up as pink powder on the base.
- Add sugar. Infusing the fruit before drying adds cheap weight. Check the ingredient line: “dragon fruit” only.
How does the season change the ratio?
Main-season fruit (April–October) arrives at 11–14 °Brix and runs at the lower end of the range. In the rainy months the fruit takes on water, Brix falls, and more flesh goes into each kilogram, so the line moves toward the 9 kg end. Rain also splits skins and brings out spots, so FruitBuys sorts harder at the gate: 5–10% of fruit is rejected in dry weather, 10–20% in the wet season. Those rejects never reach the tray, which is why a carton opened in Rotterdam or Chicago shows even magenta with no dark spots and no sour, fermented notes. Off-season fruit from lit orchards (November–March, 9–11 °Brix) is smaller, and smaller fruit carries more peel per kilogram of flesh.
For a year-round programme this matters more than the spot price. Lock an annual volume and FruitBuys allocates main-season fruit to it; your cost per kilogram and your flavour profile both stay steadier than a contract bought month to month.
What do 13–15 kg of fresh fruit put in your product?
Everything the fruit had except the water and the peel. The magenta betacyanin of a whole basket of red dragon fruit ends up in one kilogram, so a small scatter of dice turns a white cereal bowl or yogurt cup vivid pink with no added colour, and the label still reads “dragon fruit” only. The same goes for flavour: the natural sweetness of fruit picked at 11–14 °Brix is concentrated by drying, with no sugar added. For a cereal, tea or yogurt brand that means colour and taste per serving come from a light inclusion rate, which is where the cost per retail unit is decided.
How do you check a quote against the ratio?
Run the raw-material line yourself before you compare prices:
Raw fruit cost per kg finished = fresh fruit price per kg × 13–15
Fill in the farm-gate price your market reports for red dragon fruit in southern Vietnam. That figure is the fruit alone, before peeling labour, freezing, 18–24 hours of vacuum drying, packing, testing and export documents. Every extra kilogram of fresh fruit per kilogram of product adds roughly 7–8% to the raw-material line (one more kilogram on a 13–15 kg base of whole fruit; on peeled flesh, one more kilogram on 8–9 kg adds 11–13%). A quote that does not move between dry and wet season is either not sorting or not drying to the same standard.
If a quote lands below what that line supports, ask for three things before the sample ships: the release moisture and water activity on the COA, the fines percentage for your cut, and the full ingredient declaration.
| Signal in a low quote | What to ask for | What it usually means |
|---|---|---|
| Moisture spec ≤6% or “below 8%” | Release moisture and aw on the lot COA | You are buying water |
| No fines tolerance named | % through a 3 mm screen for your cut | Breakage stays in the carton |
| “Natural sweetness” with high sugars | Ingredient list; total sugars per 100 g | Sugar infusion |
| Ratio quoted at 5:1 or 6:1 “fresh to dry” | Whether “fresh” means whole fruit or flesh | Textbook number, not a working line |
Should you use 13–15 kg to convert residue results?
No, and getting this right keeps a compliant lot from being held at the border. Drying removes water, so a residue reading on freeze-dried fruit looks higher than on the fresh fruit it came from. Border labs correct for that with a processing factor based on water alone, about 6–7.4 for red dragon fruit at 4% moisture, under the EU pesticide residue rules. A reading of 0.06 mg/kg on the dried fruit is 0.01 mg/kg on the fresh basis. Peel, trimming and breakage do not concentrate residues, so the 13–15 kg production ratio never enters this calculation. Your QA team should hold that factor ready with the COA. How EU, US, UK and UAE controls apply it is covered in freeze-dried dragon fruit market compliance.
When does a different ratio apply?
The 13–15 kg chain is for whole natural pieces, slices and dice of red-flesh fruit. Powder and broken grades are milled from the same freeze-dried lots, using fruit that clears sorting but falls outside the whole-piece size tolerance. The fresh-fruit input is the same 13–15 kg; because whole cuts carry most of the raw-material cost, powder prices below them. See freeze-dried dragon fruit powder.

FAQ
What is the fresh-to-dry ratio for freeze-dried dragon fruit?
13–15 kg of whole fruit, or 8–9 kg of peeled flesh, per 1 kg of finished product at ≤4% moisture.
Why is freeze-dried dragon fruit more expensive than other dried fruit?
Each kilogram carries 13–15 kg of fresh fruit, a long vacuum drying cycle and careful sorting. Air-dried or sugar-infused fruit keeps more water or adds sugar, so it needs less fruit per kilogram.
Does the ratio change through the year?
Yes. Rainy-season fruit holds more water and is sorted harder, so the line moves toward 15 kg of whole fruit per kilogram. Main-season fruit runs toward 13 kg.
Is 6:1 a realistic ratio?
Only as a dry-matter calculation from peeled flesh. A working line also loses breakage and fines, which puts it at 8–9 kg of flesh, or 13–15 kg of whole fruit.
Does a lower ratio mean better quality?
No. A lower quoted ratio usually means higher moisture, more fines left in the carton, or added sugar. Check the COA, the fines tolerance and the ingredient line.
