How Much Fresh Pineapple Makes 1 kg of Freeze-Dried Pineapple, and Why It Sets Your Cost

Making 1 kg of finished 12 mm chunks takes 9–11 kg of trimmed flesh, which starts as 18–22 kg of whole fruit at the farm gate. That is FruitBuys Vietnam’s production mass balance, and it is the benchmark every quote should be checked against.

Fruit is about 43% of the manufacturing cost and electricity about 18%; freeze-drying uses 4–10 times the energy of hot-air drying. So the price per shipped kilogram tells you little on its own. What decides the contract is landed cost per usable kilogram: fruit, drying, freight and the share of the delivery your line can actually use.

Why does freeze-dried pineapple cost more than dried pineapple?

Because of fruit mass and drying time, not margin. FruitBuys’ cost structure for freeze-dried chunks, excluding margin:

Cost elementShareDriver
Fresh pineapple~43%18–22 kg of whole fruit per finished kilogram
Electricity~18%Vacuum and refrigeration through a cycle of about 24 hours
Labour~10%Peeling, eye removal, coring, cutting, tray loading, sorting
Packaging~8%Foil barrier bags, gently vacuumed with desiccant; 5-ply cartons
Equipment depreciation~8%Freeze-dryer capital per batch
Sorting losses~6%Broken pieces and fines screened out
QC and export documents~6%Lot testing, certificates, documentation

The physics sets a floor. Fresh pineapple is about 86% water, so 14% is dry solids. At 4% finished moisture, the minimum flesh per kilogram is (1 − 0.04) ÷ 0.14 = 6.86 kg, with no peel, drip, tray or fines loss at all. Real production of intact chunks needs 9–11 kg.

Capacity is the second constraint. One FruitBuys chamber takes about 500 kg of prepared flesh and returns about 50 kg of finished chunks per cycle of roughly 24 hours, so a 3,000 kg order uses about 60 chamber-cycles. If your product does not need crunch, fast rehydration or a single-ingredient label, air-dried pineapple is cheaper per usable kilogram; freeze-drying earns its cost only where those properties are the product.

How much pineapple goes into one kilogram at each weighing point?

Quotes differ mainly because suppliers weigh at different points. Compare them only against the same stage:

Weighing pointInput per 1 kg finishedWhat is lost before this point
Whole fruit received18–22 kgNothing yet: crown, peel, eyes and core included
Peeled fruit14–16 kgCrown and skin
Trimmed flesh9–11 kgEyes, core and cosmetic trim
Flesh on trays8.5–10.5 kgDrip and handling during cutting
Out of the dryer1.05–1.15 kgWater
Released 12 mm chunks1.00 kgBroken pieces and fines

Sweetness moves the flesh figure. High-Brix Queen fruit gives close to 9 kg of flesh per finished kilogram; fruit near the bottom of the intake range needs about 11 kg, roughly 22% more fruit for the same output.

Why do two suppliers quote such different ratios?

A ratio means nothing without its weighing point and moisture. Three mechanisms produce a ratio that looks better than the mass balance:

  1. A later weighing point. A ratio taken from flesh on trays skips the 40–60% of the fruit lost in peeling, eye removal and coring.
  2. Higher finished moisture. Every extra point of moisture means less fruit per kilogram, and pieces that soften and cake in storage.
  3. Fines left in. Without screening, broken pieces and dust stay in the carton and count as product.

Quotes built on 6–8 kg of flesh per kilogram are common, and they usually have a commercial explanation rather than a better process: flesh weighed after someone else has trimmed it (cannery off-cuts, or pre-frozen pieces that have already lost their drip), a finished product dried only to 7–8% moisture, or broken pieces and fines left in the carton. Each one shows up at your plant as pieces that bend instead of snap, dust at the bottom of the bag and colour that changes from carton to carton. In our production runs at partner facilities, peeling drip, breakage and sorting take 30–40% of the flesh that arrives, which is why FruitBuys works to 9–11 kg of trimmed flesh for intact 12 mm chunks at 3–5% moisture. Ask any supplier, including us, for the weighing point, the moisture of the lot and a batch conversion breakdown before you compare price. The moisture and water activity limits to write into the contract are in the specification guide.

Does sweeter fruit change how much pineapple goes into each kilo?

Yes. Each extra percentage point of dry matter in the fresh flesh (14% to 15%, which tracks a rise in Brix) cuts the flesh needed by about 6.7%, or 0.46 kg per finished kilogram. Across a full 20 ft container at 7 kg per carton (3,850 kg), that is about 1.8 tonnes less flesh to buy, peel and dry.

That is why FruitBuys receives retail-grade fruit at 15–17° Brix, measured by refractometer (ISO 2173), and rejects fruit below 12°: low-Brix fruit costs more per kilogram and comes out pale and sharp.

What does a kilogram really cost once it reaches your line?

Use one formula for every supplier:

Landed cost per usable kg = (price per kg + freight per kg + duty and clearance per kg) ÷ (1 − fines and defect share)

Two inputs move it most.

Carton and freight. Freeze-dried fruit fills a container by volume long before weight. FruitBuys’ 580 × 280 × 340 mm carton holds 5–7 kg net depending on cut and packing method, and 550 cartons load a 20 ft container, so a container carries 2,750–3,850 kg. Like for like at 7 kg per carton, a 600 × 390 × 390 mm carton loads 306 cartons (2,142 kg) in a 20 ft container against 550 cartons (3,850 kg) for the FruitBuys carton, about 80% more product per container.

Fines. Multi-head weighers and cereal lines cannot dose dust and crumbs, so fines are paid for and then lost.

Example at 7 kg per cartonBulky carton, 8% fines580 × 280 × 340 mm carton, 2% fines
Net per 20 ft container2,142 kg3,850 kg
Freight at an illustrative USD 3,000 per containerUSD 1.40/kgUSD 0.78/kg
Fines on a 3,000 kg order240 kg60 kg
Divisor for usable cost÷ 0.92 (+8.7%)÷ 0.98 (+2.0%)

Put your own price and freight rate into the formula: a quote that looks a few percent cheaper per kilogram can end up more expensive per usable kilogram once freight per kilogram and fines are counted. The carton and container plan is set out in how long freeze-dried pineapple really lasts.

What to request with every quote

  1. Weighing point of the quoted ratio: whole fruit, peeled fruit, trimmed flesh or trays.
  2. Moisture limit on the lot COA: 3–5% by AOAC 934.06.
  3. Water activity: ≤0.30 by ISO 18787, measured on the same sample.
  4. Conversion breakdown by weighing point from recent commercial batches.
  5. Fines limit written into the specification, with the screening method.
  6. Carton size, net weight and cartons per 20 ft and 40 ft container.
  7. Primary pack: foil barrier bag, gently vacuumed, with desiccant.

Frequently asked questions

Can anyone make 1 kg from less than 6.86 kg of flesh?

Not at 4% moisture: 6.86 kg is the dry-matter floor for flesh at 86% water. A lower figure means a different weighing basis, higher moisture or something other than pineapple in the bag; ask for the conversion breakdown.

Why is whole fruit about double the trimmed flesh?

Crown, peel, eyes and core make up roughly 40–60% of a pineapple’s weight.

How many fresh pineapples make 1 kg of freeze-dried pineapple?

About 18–22 kg of whole fruit, which is roughly 18–22 pineapples of 1 kg each. A 1 kg pineapple therefore yields about 45–55 g of freeze-dried pineapple.

Why does the conversion ratio change during the year?

Sweeter fruit carries more solids per kilogram. Mid-season Queen at the top of the 15–17 °Brix range sits near 9 kg of flesh per finished kilogram; lower-Brix fruit sits near 11 kg.
