Technical Parameters
Bulk FD Fruit Ingredient Supply
Freeze-Dried Strawberries for Food Manufacturing, Retail and Private Label
We supply freeze-dried strawberries, also traded as FD strawberries or frozen dried strawberries, in whole, sliced, diced, granulated and powder forms. We match the form, particle size, moisture limit, broken-piece tolerance, packing barrier and batch documents to your finished product.
Freeze-dried strawberries are not IQF frozen strawberries. Water is removed from pre-frozen fruit under vacuum, producing a light, porous product that is shipped dry. Moisture pickup and breakage are therefore more important purchasing risks than reefer temperature.
Whole and halved strawberry appearance reference. The approved FD sample defines finished porosity, dryness, color and breakage.
What Commercial Buyers Need to Specify
The phrase frozen dried strawberries is widely used in trade searches, but the correct process term is freeze-dried strawberries. We write the process, ingredient statement and form clearly in the quotation so the order cannot be confused with conventional dried, sugar-infused, air-dried or IQF frozen strawberries.
State whole, half, slice, dice, pieces, granules or powder. Visible inclusions and powders require different sieving, breakage and packing controls.
The standard commercial moisture limit is ≤5.0%. A stricter USDA-style project can specify ≤2.0%. Water activity can be added as a separate COA parameter.
Whole fruit, slices and dices are fragile. Define the sieve, sampling method and maximum undersize percentage instead of relying on a photograph.
Low initial moisture is not enough. The inner liner, seal integrity, headspace option, carton strength and opening exposure determine whether the product stays crisp.
Buyer Risks and Our Control Plan
| Buyer Concern | Commercial Risk | GreenLand-food Control | Order Evidence |
|---|---|---|---|
| Soft or sticky pieces | Moisture pickup, weak seal or incomplete drying | We set moisture and optional Aw limits, inspect seals and use moisture-barrier inner packing. | COA Actual Result and packing record |
| Excess powder and breakage | Wrong particle yield, poor appearance and dosing loss | We agree the size, sieve, fines limit, handling method and carton fill before production. | Approved sample and sieve result |
| Dark, pale or uneven color | Maturity variation, oxidation or process variation | We inspect raw fruit color, remove defective units and compare finished color with the agreed sample. | Sensory record and retained sample |
| Unexpected ingredient declaration | Carrier, oil, sugar or anti-caking agent affects label and formula | We state 100% strawberry for the standard program. Coated or carrier-added projects are quoted and declared separately. | Signed specification and label text |
| High freight cost | Low bulk density makes the shipment volume-limited | We calculate cartons and cubic volume from the selected form, net weight, liner and pallet plan. | Packing list and loading calculation |
Freeze-Dried Strawberry Forms and Size Programs
We use the buyer's final application to set the form. The values below are practical RFQ programs; the signed specification and approved sample remain the repeat-order standard.
Whole 15–25 mm
For visible snack, chocolate coating and decoration programs. Specify intact-piece percentage, out-of-size tolerance, broken units and fines separately.
Slices 5–7 mm
For cereal, granola, bakery decoration and retail inclusions. Thickness affects drying uniformity, breakage and visual coverage.
Dices and Cubes
Common references include 4×4 mm, 5×5 mm, 6.4 mm and 10×10 mm. USDA's 6.4 mm dice reference limits material passing a No. 8 sieve to 10%.
Pieces and Granules
Programs such as 1–5 mm or 2–10 mm provide controlled distribution in dry mixes. The order states the top sieve, bottom sieve and fines tolerance.
Strawberry Powder
Particle size is written by mesh or micron target. Pure fruit powder and powder with a carrier or anti-caking agent are different products and receive different declarations.
Caliper measurement records strawberry size before the freeze-dried form and tolerance are approved.
Detailed Commercial Specification
A quotation becomes repeatable only when every measurable item has a limit and method. We use the following board as the starting point, then issue the final product specification for the selected form and destination market.

From Strawberry Material to Finished FD Product
- Raw material inspection: We review maturity, red color, flavor, decay, bruising, green units, calyx condition and foreign material.
- Washing and preparation: We wash, destem, trim and prepare the contracted whole, slice or dice form.
- Pre-freezing: The prepared fruit is frozen so its internal water becomes ice before vacuum drying.
- Primary drying: Under vacuum, ice sublimes directly to vapor. Product temperature and chamber pressure are controlled through the drying cycle.
- Secondary drying: Residual bound moisture is reduced to the contracted limit.
- Sorting and packing: We inspect color, form, crispness, fines and foreign material, then pack promptly in the approved high-barrier liner.

Defect, Fines and Metal-Control Standard
Freeze-dried fruit is fragile. We do not treat every broken piece as a safety defect, but the purchase order must separate acceptable form variation from excessive mechanical damage. The inspection plan states sample weight, sieve opening, shaking time and whether the result is calculated by weight or piece count.
Glass, metal, hard plastic, stones, infestation, visible mold, wet product, foreign odor or evidence of seal failure.
Burnt or brown pieces, severe discoloration, leathery texture, excessive white core, undeclared calyx, excessive fines or wrong form.
For a whole 15–25 mm program, a practical reference is ≤10% below the agreed lower sieve and ≤10% fines below 1 mm, unless the signed specification states otherwise.
A sensitive loose-product reference is Fe 0.8 mm, Non-Fe 1.2 mm, stainless steel 1.6 mm and aluminum 1.0 mm. Final validated sensitivity depends on product and pack.
Weight checks connect received material, processed batch and finished carton records.
Microbiological Specification and COA
Low moisture limits microbial growth during correct storage, but freeze-drying is not a sterilization step. We therefore set microbiological limits for the destination market and finished application. The table below is a commercial reference for a whole or piece program.
| Test | Specification Limit | COA Reporting |
|---|---|---|
| Total Plate Count | ≤50,000 cfu/g | Batch Actual Result, cfu/g |
| Coliforms | <10 cfu/g | Batch Actual Result |
| E. coli | <10 cfu/g | Batch Actual Result |
| Yeasts | <1,000 cfu/g | Batch Actual Result |
| Moulds | <1,000 cfu/g | Batch Actual Result |
| Salmonella | Negative / 25 g | Negative / 25 g |
COA rule: the Specification column is the contractual limit. The Actual Result column contains the measured value from the corresponding production batch. A limit is never copied into the Actual Result field as though it were a test result.

Raw Material, Color and Sensory Approval
We inspect ripe, sound strawberries and remove decay, severe bruising, green fruit, foreign plant material and unacceptable calyx residue. The finished FD product should have a strawberry-typical aroma and taste without burnt, stale, rancid, fermented or moldy notes.
Natural variation remains visible because the standard ingredient is strawberry rather than an artificially colored compound. We therefore agree a physical sample for red exterior color, pink interior, seed visibility, pore structure, crispness and acceptable pale areas.
For formula trials, evaluate the FD strawberry in the actual finished matrix. Chocolate, cereal, tea, dry mix and dairy applications expose the product to different humidity, fat, shear and storage conditions.
Packaging That Protects Crispness and Piece Yield
Freeze-dried strawberries absorb atmospheric moisture quickly and break under compression. We select the inner bag, carton fill and handling method together instead of treating packaging as a final label decision.
High-barrier foil laminate or validated moisture-barrier liner in a strong carton. Common project references are 5, 7 or 8 kg net per carton.
A sealed high-barrier inner bag controls humidity and powder leakage. Common project references are 10 or 15 kg net per carton.
We review pouch barrier, zipper, desiccant or gas option, net weight, artwork, barcode, label language, carton marks and case pack.
FD strawberries are lightweight and volume-limited. Carton dimensions, form, fill level and pallet use determine the loading quantity.
Carton packing example from the product record; final liner, net weight, label and case dimensions are written into the order.
Application Matching by Product Form
Snack and Retail Packs
Whole and large pieces need strong visual identity, low breakage, crisp texture, high-barrier pouches and a clearly declared ingredient list.
Cereal and Granola
Slices, dices or 2–10 mm pieces provide controlled distribution. Test humidity migration and breakage through mixing, filling and shelf-life trials.
Chocolate and Confectionery
Whole fruit, slices, dices and powder require compatibility tests for coating temperature, fat contact, moisture migration and final bite.
Bakery and Decoration
Slices and pieces supply visible color; powder provides even flavor distribution. Particle size and dosage should be approved in the final formula.
Tea and Beverage Blends
Pieces and granules are assessed for aroma release, floating or sediment behavior, infusion time and visual identity after rehydration.
Dairy and Dry Mixes
Dices, granules or powder require a controlled sieve profile, microbiological specification and moisture protection through the customer's blending process.
Documents, Compliance and Batch Traceability
We connect the finished lot with raw-material receipt, preparation, drying, sorting, packing and shipment records. The standard export file can include the signed specification, batch COA, packing list, commercial invoice, lot coding and origin documentation.
By destination market and order agreement, we prepare or coordinate microbiological testing, pesticide-residue reporting against the applicable MRL framework, heavy-metal reporting, allergen statement, GMO statement, nutrition data and certificate copies relevant to the supplying facility.
Organic wording is used only for an order covered by valid organic scope and transaction documentation. A generic certificate image does not make every freeze-dried strawberry batch organic, kosher, halal or certified under every displayed scheme.
General facility and compliance document display. Applicable certificates are matched to the supplying site and contracted order.
Generic export-loading example. Freeze-dried strawberry shipments use dry, clean transport with humidity and carton protection.
Dry Export Logistics, Not Frozen Cold Chain
Finished freeze-dried strawberries are normally shipped as dry goods in sealed moisture-barrier packaging. They do not require the −18°C reefer chain used for IQF strawberries unless a separate contract specifically requires temperature-controlled transport.
We inspect carton condition, labels, lot codes, pallet stability where applicable, container cleanliness and protection from water ingress. The loading plan is based on carton dimensions and cubic volume because whole and sliced FD fruit has low bulk density.
For an accurate freight comparison, send the required form, net weight per carton, pallet requirement and destination port. We return the carton count, gross weight, cubic volume and trade term in the quotation.
Sample Approval and Repeat-Order Control
Record freeze-dried, not IQF or conventional dried; state 100% strawberry or every added ingredient.
Approve form, size, sieve profile, color, crispness, whole-piece yield and fines limit.
Approve moisture, optional Aw, microbiology and market-specific chemical tests.
Review liner barrier, seal, net weight, headspace, carton strength and breakage after transport simulation.
Connect the approved sample and signed specification with the batch COA and shipment lot code.
Sampling, Laboratory Results and Lot Release
A laboratory number is useful only when the sample represents the shipment. For a strict moisture-verification program, a practical reference is a 227 g composite prepared from five randomly selected subsamples. Moisture is reported to the nearest 0.1%. We write the sampling plan, test method, laboratory responsibility and acceptance rule into the order file when independent release testing is required.
Lot release combines more than the COA. We review the ingredient declaration, production date, lot code, packaging material, seal condition, net weight, sensory result, particle-size result, moisture result, microbiological result and required market documents. If the order includes Aw, metal-detector verification, pesticide residues, heavy metals or nutrition analysis, each item receives its own specification line and corresponding result or report reference.
A pre-shipment sample should remain sealed until evaluation because open-air exposure can change crispness and moisture. When comparing two factories, use the same sample mass, room condition, sieve, evaluation time and application test. This prevents a newly opened sample from being compared with a sample that has already absorbed humidity.
Price and Yield Factors Behind an FD Strawberry Quote
Freeze-dried strawberry price cannot be compared by kilogram alone. About 10 kg of fresh strawberry can be required for approximately 1 kg of finished FD product, although the actual conversion changes with raw-fruit water content, trimming loss, form, final moisture and sorting yield. Whole 15–25 mm fruit normally produces a different usable yield from pieces or powder because appearance and breakage limits remove more off-size material.
Variety, crop period, maturity, color, Brix, decay removal, calyx removal and usable yield influence the raw-material cost.
Whole fruit, calibrated slices, tight dices and fine powder have different preparation, drying, sieving and breakage yields.
A ≤2.0% moisture project, tighter microbiology, additional residues or destination-market laboratory work changes testing and process cost.
High-barrier laminate, gas or desiccant option, retail artwork, carton cube, pallet use and low bulk density affect delivered cost.
For a useful quotation comparison, request the same form, size distribution, moisture, Aw, microbiology, fines limit, ingredient declaration, net weight and Incoterm from every supplier. A lower unit price can be offset by excess fines, low whole-piece yield, weak barrier packing or a high cubic freight cost.
Label and Carton-Mark Information
For bulk ingredient cartons, we prepare the product name, form, net weight, lot number, production date, best-before date, country of origin, storage instruction and consignee marks required by the order. The inner bag and outer carton must carry compatible lot identification so receiving teams can connect every opened liner with the COA.
For retail private label, we review the legal product name, ingredient list, nutrition panel source, allergen statement, net quantity, serving information where required, date coding, storage text, origin wording, importer details, barcode and local-language artwork. Printing begins only after the agreed artwork version is recorded with the packing specification.
Frequently Asked Questions
1. Are frozen dried strawberries the same as freeze-dried strawberries?
The trade phrase often refers to freeze-dried strawberries, but it can be confused with IQF or conventional dried fruit. We write "freeze-dried / FD" in the specification and process description.
2. What is the difference between FD and IQF strawberries?
IQF strawberries remain frozen and require a frozen chain. FD strawberries have most water removed under vacuum, are light and porous, and require dry moisture-barrier packing.
3. Which freeze-dried strawberry forms are available?
We quote whole, halves, slices, dices, pieces, granules and powder. Availability, size and MOQ are written for the selected production program.
4. Which sizes can be specified?
Common RFQ references include whole 15–25 mm, slices 5–7 mm, dices 4×4, 5×5, 6.4×6.4 or 10×10 mm, and pieces 1–5 or 2–10 mm.
5. What moisture limit is used?
Our standard commercial limit is ≤5.0%. A strict USDA-style purchase program can specify ≤2.0%; the batch COA reports the measured Actual Result.
6. Can water activity be added to the COA?
Yes. A target such as ≤0.30 Aw can be written into the test plan. Moisture percentage and water activity are different measurements and should appear on separate lines.
7. How are broken pieces and fines controlled?
We agree the bottom sieve, top sieve, sample weight, test time and maximum undersize percentage. The approved sample also defines acceptable natural irregularity.
8. Are sugar, preservatives or colors added?
The standard program is declared as 100% strawberry without added sugar, color or preservative. Any oil coating, carrier or anti-caking agent is a separate product and must be declared.
9. What microbiological limits are available?
A reference program uses TPC ≤50,000 cfu/g, Coliforms and E. coli <10 cfu/g, Yeasts and Moulds <1,000 cfu/g, and Salmonella Negative/25 g.
10. What is the shelf life?
The stated program is 24 months from production in unopened, intact moisture-barrier packing at ≤20°C and ≤65% RH. Shelf life changes if the pack or storage condition changes.
11. Which bulk packing formats are used?
Pieces commonly use 5–8 kg high-barrier inner bags in cartons; powder projects commonly use 10–15 kg cartons. The final liner and net weight are quoted with the form.
12. Can you prepare retail or private-label packs?
Yes. We review pouch barrier, zipper, gas or desiccant option, net weight, artwork, barcode, language panel, carton marks and case pack.
13. What is the MOQ?
The standard bulk MOQ is 20 cartons. A special cut, powder specification or custom retail pack may require a separate production MOQ.
14. Do freeze-dried strawberries require a refrigerated container?
Normally no. Finished FD fruit is shipped dry in sealed moisture-barrier packaging. The transport plan focuses on humidity, water ingress, heat exposure and carton compression.
15. What information is needed for a quotation?
Send the form, size, moisture or Aw target, fines limit, packing, quantity, application, destination market, port, private-label needs and required documents.
