How many kilos of mangosteen make 1 kg of freeze-dried?

About 17–24 kg of whole fruit, or 5–6 kg of hand-peeled aril with its seed, for every 1 kg of freeze-dried mangosteen. That is the operating ratio FruitBuys sets for every contract, and it is the most useful number you have when two quotes for the same product sit far apart. Freeze-drying takes out the water and keeps everything else, so the kilo in your bag holds the sugar, fibre and flavour of five to six kilos of fresh segments. When a price cannot cover that much fresh fruit, something other than mangosteen is filling the gap.

Why does it take 17–24 kg of fruit and 5–6 kg of aril?

Two losses stand between the orchard and the bag, and the first is the bigger one. Most of a mangosteen is rind. Rind, calyx, stem and the fruit sorted out at intake account for about 70–75% of what arrives at the gate, so 1,000 kg of fruit yields about 250–300 kg of aril with its seed. The second loss is water. That aril goes into the dryer and comes out at about one-fifth of its weight.

What moves the aril ratio between 5 and 6?

Because fresh mangosteen aril is mostly water, and freeze-drying removes almost all of it. The arils go into the dryer soft and juicy and come out at ≤5.0% moisture, with a release target of 3%. What is left is the fruit’s solids: natural sugars, fibre and the aroma compounds that give mangosteen its sweet-tart taste.

Three things move the ratio within that range, and anyone who has stood on a peeling floor in June will recognise all three. Sugar content: fresh aril runs 16–19 °Brix across the season, and fruit at the top of that range carries more solids per kilo, so the ratio sits near 5. Weather: after a run of heavy rain the segments take up water, Brix drops and the ratio drifts toward 6. Peeling: a careful hand lifts each segment out whole; a rushed one bruises it and leaves juice on the table, and every lost drop is solids that never reach the dryer. Both ends of 5–6 are normal; a ratio well outside them is not.

For your team, that gives one clean test: a supplier quoting 17–24 kg of fruit, or 5–6 kg of aril, per kilo is describing real mangosteen dried to a real moisture target. A supplier who cannot tell you their ratio has not done the arithmetic you are about to do.

Where does the cost of freeze-dried mangosteen actually sit?

In the peeling, long before the dryer. Every aril is lifted out of a thick purple rind by hand, whole, with its segments still joined. The rind is hard on the outside and soft on the inside, and a fragment left behind makes the mouthful bitter, so the work needs care as well as speed. Skilled peelers work fast, and they work with the fruit under water, so the yellow latex in the rind does not stain the white flesh. Each kilo of clean aril is still the work of many hands, and that work happens against the clock: fresh mangosteen holds for only 7–10 days at 13 °C after harvest. Early in the season the same peelers are also in demand for green mangosteen, peeled for the salads Lai Thieu is known for, which is one more reason volume is booked before the crop starts.

That is why freeze-dried mangosteen is scarce, and why it stands out on a shelf. For a snack, chocolate or cereal brand, that scarcity is the point: a fruit most shoppers have heard of and few have tasted gives a pack a reason to be picked up, and a reason to carry a higher retail price than the mango and pineapple next to it. You are not paying for an exotic name. You are paying for 17–24 kilos of fruit that trained hands opened, cleaned and moved into the freezer within the fruit’s short life. Clean ivory segments with no purple on them are the visible proof that the work was done properly.

How does the harvest calendar change yield and taste?

The main crop runs May to August, and the best raw material for freeze-drying comes from May to mid-July. In that window, fruit size, Brix and colour are at their best: segments are large and firm, the ratio sits toward the efficient end of 5–6, and the dried segments keep the bright ivory colour that sells a window pouch.

Later in the season, fruit gets softer and more variable. It still makes good freeze-dried mangosteen, but it suits diced and powder better than whole arils, because shape matters less and the flavour carries through. A small off-season crop around Tet adds about 10–15% of main-season volume, enough for top-up orders but not for a programme.

The best arils of that window are frozen at −25 °C and freeze-dried to order through the year, so your containers ship in any month with a recent production date. The practical consequence: confirm your volume before April. The amount frozen in the peak window sets how many whole arils exist for the next twelve months; volume that arrives after mid-July is still served, as diced or powder from late-season fruit. Seasonal planning is set out in detail in where and when Vietnam’s mangosteen is harvested.

How do you tell whether a quote is realistic?

Rebuild it from the fruit up. FruitBuys sets out this cost structure openly, because a buyer who understands where the money goes can defend the budget to their own management and spot a weak offer in minutes.

StepWhat to enterExample of the logic
1. Raw materialPrice per kg of whole fruit × 17–24, or of peeled aril × 5–6The floor cost of fruit in 1 kg of product
2. DryingFreeze-drying cost per kg of finished productEnergy and dryer time
3. PackingFoil bag, desiccant, 5-ply carton per kgWhole arils pack only 7 kg per carton, so packing cost per kg is higher than diced
4. FloorSum of 1–3Any quote well below this line is not buying 5–6 kg of mangosteen

When a quote lands under that floor, the usual explanations are three, and each leaves a trace you can check:

  • Sugar infusion. Segments soaked in syrup before drying weigh more and cost less fruit per kilo. Ask for the ingredient line: anything other than “100% mangosteen” means added sugar, which has to be declared on the label in every main market. Natural total sugars in freeze-dried mangosteen sit around 70 g per 100 g; infused product usually runs higher and shows added sugars on the panel.
  • Late-season or reject fruit. Cheaper fruit, softer segments, more browning and more breakage. Ask for the production month and look at the colour on the sample.
  • Rushed peeling. Fewer hands, more purple rind left on the segments and more bruised, broken pieces. Clean, whole ivory arils on the sample are the signature of proper peeling; at FruitBuys, rind sorting is part of the release check on every lot.

These checks apply to every supplier, including us. A sound quote passes them easily.

What does the ratio mean for your own costing?

Use it to build landed cost per kilo before you compare any offer:

Landed cost per kg = (FOB price per kg) + (freight per container ÷ kg per container) + import duty + broker and port charges per kg

Kg per container is where format matters most: about 3.85 t of whole arils, 5.5 t of diced or 11 t of powder in a 20ft. Duty depends on the line and the market, and for the US add any trade tariffs in force on the entry date; the reference rates are in which HS code freeze-dried mangosteen ships under.

It tells you how to compare freeze-dried mangosteen with the fresh or frozen fruit your team might otherwise use. One kilo of freeze-dried mangosteen carries the solids of 5–6 kilos of fresh aril, in a bag that needs no cold chain, ships in a standard dry container and stays usable for 12 months at ≤25 °C, RH ≤60%. When your R&D team calculates cost in use, divide the price of a kilo of freeze-dried by 5–6 to compare it with fresh aril on an equal-fruit basis, then add back what fresh would cost you in freezing, cold storage and waste.

Format changes the freight side of the same sum. A 20ft container carries about 3.85 tonnes of whole arils, 5.5 tonnes of diced or 11 tonnes of powder, so freight per kilo of fruit solids is lowest for diced and powder. Choose whole arils where the shape earns its place on shelf, and diced where the fruit disappears into a recipe. The trade-off by application is set out in which freeze-dried mangosteen format fits your product, and container loading in how freeze-dried mangosteen should be packed and loaded.

When does this ratio not apply?

When the product is not plain freeze-dried mangosteen. Sugar-infused segments, mangosteen blended with other fruit, or powders built on a carrier such as maltodextrin all follow different arithmetic, and comparing their price with 100% freeze-dried mangosteen tells you nothing. Compare like with like: same ingredient line, same format, same moisture target. FruitBuys mangosteen powder is milled from freeze-dried segments with no carrier; see what to specify for bulk freeze-dried mangosteen powder.

FAQ

How many kilos of mangosteen make 1 kg of freeze-dried mangosteen?

About 17–24 kg of whole fruit, or 5–6 kg of hand-peeled aril with its seed. Higher-Brix main-season fruit sits near the low end, softer fruit near the high end.

Why is freeze-dried mangosteen more expensive than other freeze-dried fruits?

Most of the fruit is rind, every aril is peeled by hand within a fresh-fruit life of about a week, and 17–24 kg of fruit goes into each finished kilo.

When is the best time to buy?

Confirm volume before April. The best arils come from May to mid-July; they are frozen at −25 °C and freeze-dried to order, so shipments run all year.

How can I spot sugar-infused mangosteen?

Check the ingredient line for anything other than “100% mangosteen” and look for added sugars on the nutrition panel. Plain freeze-dried mangosteen carries around 70 g of natural sugar per 100 g.

Does the ratio change by format?

No. Whole arils, diced and powder all start from the same 17–24 kg of fruit; format changes carton weight and freight per kilo, not the fruit in it.
