IQF Frozen Plum Halves and Pitted Plums for Bulk Supply
We supply IQF frozen plums in pitted halves, whole fruit, quarters, slices, dice and broken pieces for industrial processing, foodservice and private-label programs. We confirm cultivar, cut, pit-control standard, maturity, Brix, packing and microbiological requirements against each order before production.
Frozen Plum Supply Built Around the Final Use
Plum specifications change with the finished product. Bakery fillings need controlled piece integrity; puree and sauce production can accept more flexible appearance; retail packs require tighter color, size and defect control. We prepare the order around the intended application instead of presenting one generic plum grade for every program.
We commonly prepare skin-on IQF pitted plum halves. We also produce whole plums, quarters, slices, 10 x 10 mm dice and processing pieces. Each quotation states the exact form, size, cultivar, packing and quality limits we will deliver.
Pitted plum halves give processors a recognizable fruit shape with fewer preparation steps.

Buyer Risks and GreenLand-food Controls
| Order Risk | Why It Matters | Our Control |
|---|---|---|
| Mixed maturity or unstable color | Flavor, Brix and finished-product appearance vary. | We define cultivar, maturity and color expectations with the approved sample. |
| Whole stones or pit fragments | Pit material can damage equipment and create a foreign-material risk. | We specify pitting checks, whole-stone absence and a measurable fragment tolerance. |
| Excess broken pieces | Usable yield and visible fruit identity decline. | We agree the form, size band and defect method before production. |
| Thawing or temperature abuse | Drip loss, softness and clumping increase. | We maintain frozen storage, inspect loading condition and provide handling guidance. |

Raw Material, Variety and Crop Control
We source processing plums from approved growing and collection areas in China. Heibulang, Angeleno and other suitable dark plum varieties may differ in skin color, flesh tone, sweetness, acidity and firmness, so the cultivar is not treated as interchangeable without approval.
The main processing window is generally June through September, with timing affected by region, variety and weather. We link incoming fruit, production date and finished lots so crop variation can be discussed against the actual shipment.
Raw-material and batch records connect crop intake with finished frozen lots.
Physical and Sensory Quality
We check that frozen plums retain the expected natural varietal color, clean plum flavor and freedom from fermentation, decay, objectionable odors and visible foreign matter. Size and shape tolerances are measured on the frozen product using the method stated in the order.
Frozen and thawed plums are naturally softer than fresh fruit. A specification should therefore separate frozen appearance, thawed texture and finished-application performance instead of promising fresh-fruit firmness after thawing.
Pitting and Foreign-Material Control
Pitted product requires two separate controls: whole stones and pit fragments. We state whole stones as absent and control visible fragments to the numeric tolerance confirmed in the order. A maximum of 1 visible fragment per 10 kg can be applied after the selected production line and cultivar have been confirmed.
We confirm the pitting process, inspection frequency, metal-detection standard and corrective action with the selected plant. Orders with tighter limits require a feasibility review and may affect sorting cost, yield and lead time.
Inspection criteria are tied to the approved order specification and sampling plan.
Typical IQF Processing Flow
Microbiological Reference and Intended Use
Our order specification can control total plate count to no more than 500,000 CFU/g, coliforms to no more than 1,000 CFU/g, E. coli to no more than 100 CFU/g, yeast and mould to no more than 100 CFU/g, and Salmonella as negative in 25 g. Listeria monocytogenes negative in 25 g is included when required by the market or intended use.
IQF freezing is not a sterilization step. Direct-consumption or ready-to-eat status must be expressly validated through raw-material control, process design, hygiene zoning, testing and the destination-market standard. Otherwise, we position the plums as an ingredient for further processing.
Residue, Contaminant and Document Control
We align pesticide-residue and contaminant testing with the destination market, customer specification and approved laboratory scope. The analyte list and maximum residue limits are confirmed for each order.
Available documents can include specification, COA, packing list, commercial invoice, certificate of origin, phytosanitary certificate when applicable, health certificate, microbiological report, residue report and inspection report. The exact set is confirmed before shipment.
Certificate validity, issuing body and applicable production scope should be checked for the selected order.
Application Matching
Bakery and dessert: pitted halves, quarters or dice with defined piece integrity and thawed-drip expectations.
Jam, puree and sauce: halves, dice or pieces selected around yield, Brix, color and pit control.
Beverage and dairy: dice or smaller pieces with a defined microbiological plan and processing declaration.
Foodservice and private label: portion size, bag strength, retail artwork, coding and destination-market labeling confirmed before production.
Thawing and Handling Guidance
Maintain -18 degrees C or below and limit temperature fluctuation during storage and transfer.
Use a covered food-safe container and allow for natural juice release.
Evaluate the thawed product in the intended recipe, not against fresh-fruit firmness.
Do not refreeze thawed product unless a validated industrial process specifically permits it.
Packing and Private-Label Programs
Our common bulk references are 10 kg and 20 kg cartons, 4 x 2.5 kg bags, and 20 lb or 40 lb cases. Retail references include 20 x 500 g and 10 x 1 kg. Large tote packing up to about 600 kg is considered only after factory and product-form confirmation.
We state the inner-film specification, carton strength, net weight, coding, pallet pattern, label language and artwork responsibility in the packing approval. We can combine pitted halves and dice in one container when both products use the same loading port, shipment week and carton footprint. We list the quantity of each SKU in the loading plan.
Frozen Storage and Batch Release
We hold finished lots in frozen storage and connect pallet identification with production and inspection records. Release is based on the agreed product specification, required test results, packing confirmation and shipment instructions.
Cold-Chain Planning
We coordinate the loading window, reefer set point, carton condition and shipment documents before dispatch. A floor-loaded 20-foot reefer carries about 12 MT, while a floor-loaded 40-foot reefer carries 22-24 MT. For palletized cargo, we calculate the carton count from the approved carton dimensions and pallet pattern and show the resulting net weight in the loading plan.
Loading and Shipment Evidence
Loading photos, seal records and pre-shipment observations can be included when required. We use them to document carton condition, loading sequence and container readiness rather than as a substitute for the signed quality specification.
GreenLand-food Frozen Fruit Supply Support
We coordinate product selection, specification alignment, packing, document preparation, inspection and export shipment through a practical buyer-facing workflow. For a broader sourcing program, review our frozen fruit solutions, quality control system, traceability process and factory audit and inspection support.
Concrete Specification Programs We Can Supply
Procurement teams often need more than a broad product name. The examples below show how we turn "frozen plum" into a production-ready order. Each program has a defined fruit form, quality target, packing format and intended use. This allows the receiving warehouse and quality team to inspect the same characteristics that the purchasing team approved.
Bakery Halves Program
We supply skin-on, pitted dark plum halves with natural red-to-purple skin, clean flesh, whole stones absent, visible pit fragments controlled to a maximum of 1 piece per 10 kg, broken or damaged pieces controlled to a maximum of 10%, clumps over 3 pieces controlled to a maximum of 5%, and free ice controlled to a maximum of 1%. Packing options include 10 kg cartons or four 2.5 kg bags in one carton. This program gives pie, tart and pastry producers recognizable fruit pieces after filling preparation.
Jam and Puree Program
We supply pitted halves, irregular pieces or 10 x 10 mm dice with Brix bands of 11-13, 13-15 or 15-18 degrees Brix. The program emphasizes usable fruit yield, natural plum color, clean flavor and pit control. A wider piece-size range is available because the fruit is crushed or cooked during manufacturing. Bulk packing includes 10 kg, 20 kg, 20 lb and 40 lb cases. We can include Brix and pH results on the COA.
Dairy and Dessert Dice Program
We supply pitted plum dice in a 10 x 10 mm target cut for yogurt preparations, ice cream inclusions, dessert sauces and portioned cups. The specification records the cut-size tolerance, fines limit, skin-on status, Brix band, pH range, microbiological limits and packing format. We offer four 2.5 kg bags in a carton for production-line portion control and ten 1 kg bags for foodservice distribution.
Foodservice and Retail Program
We pack pitted halves, quarters or dice in 500 g, 1 kg and 2.5 kg bags. Retail configurations include 20 x 500 g and 10 x 1 kg per carton. We can print or apply private-label artwork, product name, country of origin, lot code, production date, best-before date, storage statement, net weight and preparation instructions. Master cartons can carry shipping marks, barcode labels and importer information.
What We Check During Production
Our quality-control work is built around visible and measurable acceptance points. We do not describe quality only with words such as "premium" or "high grade." The inspection record identifies what was checked, the sampling quantity, the result and the action taken when the product moves outside the approved limit.
| Inspection Stage | What We Check | Example Record |
|---|---|---|
| Raw-fruit receiving | Cultivar identity, maturity, decay, fermentation, foreign matter, fruit temperature and incoming lot code | Supplier lot, receiving time, accepted quantity and rejected quantity |
| After washing and sorting | Leaves, stems, damaged fruit, underripe fruit, overripe fruit and surface cleanliness | Sorting-line check with defect observations and corrective sorting action |
| After pitting and cutting | Whole stones, visible pit fragments, cut form, cut size, damaged flesh and excessive small pieces | Sample weight, fragment count, broken-piece percentage and operator action |
| After IQF freezing | Individual freezing, clumps, free ice, color, odor, frozen temperature and package weight | Finished-lot sensory result, temperature result and net-weight result |
| Before lot release | Specification compliance, microbiological results, packing, coding, metal detection and document completeness | Release signature linked to production lot and pallet identification |
Documents and Evidence We Can Provide
International orders need a document package that matches the physical shipment. We can provide a signed product specification showing product form, ingredient statement, origin, packing, storage, shelf life, physical tolerances and microbiological limits. The COA can show the production lot, production date, Brix, pH and the microbiological results included in the release plan. The packing list shows carton count, net weight, gross weight and shipping marks, while the commercial invoice records the agreed trade information.
For import clearance, we can prepare a certificate of origin, health certificate and phytosanitary certificate when the product and destination require them. Residue and contaminant reports can cover the analytes listed in the purchase specification. We can also provide carton photographs, label photographs, pallet photographs, container-loading photographs, seal information and an inspection report. For private-label orders, the approval file can include the final artwork, barcode, bag dimensions, carton dimensions, coding position and print sample.
A practical document set for one 40-foot reefer shipment may include the signed specification, commercial invoice, packing list, COA, certificate of origin, health certificate, bill-of-lading draft, loading photographs and seal record. When residue testing or an additional microbiological panel is included, the laboratory report is linked to the same finished-product lot. This keeps the shipment identity consistent from production through customs clearance and warehouse receipt.

Information Included in Our Quotation
Our quotation names the offered product instead of using only "frozen plum." For example: "IQF Frozen Dark Plum, skin-on, pitted halves, Heibulang variety, Brix 13-15 degrees, pH 2.7-3.5, broken pieces maximum 10%, whole stones absent, visible pit fragments maximum 1 per 10 kg, packed 1 x 10 kg blue food-grade PE bag in one export carton." This description gives the purchasing team a clear basis for price comparison.
The quotation also states the MOQ, carton net weight, estimated carton count, container loading quantity, unit price basis, loading port, payment terms, production lead time, shipment window and quotation validity. Separate lines identify private-label bag costs, printing-cylinder costs, pallet costs, special laboratory tests and inspection services when these items are included. This prevents packaging or testing charges from appearing late in the order.
After commercial approval, we issue the product specification and packing artwork for signature. Production uses those approved documents. Before shipment, we check the finished lot against the physical limits, microbiological plan, packaging details and coding requirements stated in the order. The same product name and lot identity then appear on the COA, packing list, cartons and shipment records.
Frequently Asked Procurement Questions
1. Which frozen plum forms do you supply?
We supply pitted halves, whole pitted fruit, whole unpitted fruit, quarters, slices, 10 x 10 mm dice and processing pieces. The quotation lists only the forms available for the requested shipment window.
2. Are the plums pitted?
We mainly supply pitted halves. Whole fruit must be marked clearly as pitted or unpitted in the order.
3. Is a frozen plum the same as a prune?
No. We describe frozen fresh plum fruit. A prune generally refers to a dried plum or a cultivar commonly used for drying.
4. What Brix range can you supply?
Our broad reference is 11-18 degrees Brix. Cultivar, maturity, crop and test temperature affect the result, so the order must state the target.
5. What is the typical pH?
We normally control pH within 2.7-3.5. We confirm the applicable method and lot result when pH is a release parameter.
6. Can you control cut size and uniformity?
Yes. We define diameter, thickness or dice size with tolerances and an agreed frozen-product inspection method.
7. What is the broken-piece limit for pitted halves?
We control broken or damaged pieces to a maximum of 10% for standard pitted halves. A different limit requires sample and production confirmation.
8. How do you control stones and pit fragments?
We specify whole stones as absent in pitted product and inspect visible pit fragments during pitting, sorting and final product checks. We can supply a specification with a maximum of 1 visible fragment per 10 kg.
9. Will the plum remain firm after thawing?
No frozen plum should be expected to match fresh-fruit firmness. We recommend testing thawed texture and drip loss in the intended formulation.
10. Can the product be eaten directly after thawing?
Only when a ready-to-eat program has been expressly validated and documented. Standard IQF fruit should not automatically be treated as sterile.
11. What are the storage temperature and shelf life?
Keep the product at -18 degrees C or below. We supply it with a shelf life of up to 24 months under uninterrupted frozen storage.
12. Which packing formats are available?
Common formats include 10 kg, 20 kg, 4 x 2.5 kg, 20 lb and 40 lb bulk packs, plus 20 x 500 g and 10 x 1 kg retail configurations.
13. What is the MOQ and container loading quantity?
Our MOQ is 12 MT. A floor-loaded 20-foot reefer carries about 12 MT. A floor-loaded 40-foot reefer carries 22-24 MT. Palletized orders carry fewer cartons, and we show the calculated carton count in the quotation.
14. Which documents can accompany the shipment?
We confirm the required specification, COA, origin, health, phytosanitary, residue, microbiological, invoice, packing-list and inspection documents before shipment.
15. Can you support a pre-shipment inspection?
Yes. We coordinate pre-shipment checks against the signed specification and agreed sampling plan.
