Mulberry Dark Frozen
Description
Technical Parameters
Premium IQF Frozen Dark Mulberries Supplier
We supply premium IQF frozen dark mulberries for importers, frozen-fruit distributors, food manufacturers, foodservice operators and private-label programs. This selected grade focuses on natural dark purple-to-black color, controlled maturity, a high whole-berry ratio and consistent frozen condition.
Available forms include natural uncalibrated whole berries and calibrated 13-17 mm berries. We match Standard Dark Whole and Premium Dark Whole grades according to Brix, color ratio, whole-berry integrity, broken-fruit tolerance, juice leakage and final application.
Send your required size, Brix, dark-color ratio, whole-berry ratio, packing, quantity, destination and test list. We will review the current crop, sample, COA scope and reefer loading plan before quotation.

What We Supply as Premium Frozen Dark Mulberries
The term dark mulberry describes the commercial fruit color, not a guaranteed botanical species. Dark-fruited cultivars can belong to different Morus species, so we use Morus spp. until the raw-material documentation confirms the species or cultivar.
Selected for visible retail, fruit-cup, dessert and premium foodservice applications.
Balanced whole-fruit, color and Brix targets for dairy, bakery and smoothie programs.
Measured at the widest berry diameter under the agreed inspection method.
Natural crop size for general manufacturing where exact sizing is not essential.
Current-lot photos help confirm natural color distribution, berry size, short pedicels and whole-fruit condition.

Buyer Risks and GreenLand-food Controls
Dark mulberries are delicate. Orders can fail when a high-Brix claim is not supported by the current lot, whole-fruit and dark-color ratios are undefined, natural short pedicels are confused with long stems, or thawing produces excessive crushed fruit and juice blocks. We turn those risks into measurable order points.

Specification note: Mulberries are a natural agricultural product. Size, Brix, pH, acidity, color and texture vary by species, cultivar, maturity, weather and lot. We confirm binding requirements through the approved sample, final specification and sales contract.
Brix, pH and Acidity Control
We evaluate Brix together with pH, titratable acidity, maturity, aroma and fruit condition. A 15°Bx minimum is reserved for a selected high-Brix lot and must be verified before order confirmation.
Brix ≥10°Bx.
Brix ≥11°Bx.
Brix ≥15°Bx by lot test.
3.60-4.60 reference.
0.80-1.80 g/100 g as citric acid.
For a contract COA, we test representative thawed berries, press and filter the juice, measure Brix near 20°C with a calibrated refractometer and use the agreed pH and titration methods.
Dark appearance is assessed separately from Brix; color alone does not prove sweetness or anthocyanin content.
Dark Purple-to-Black Color Grade
We evaluate color under consistent lighting using a representative frozen sample. Natural variation from dark purple to black is acceptable, while red, pale, colorless, under-ripe or abnormally brown fruit is controlled by weight.
Minimum 95%.
Minimum 90%.
Maximum 3%.
Maximum 3%.
Dark color is a commercial maturity and appearance parameter. We publish an anthocyanin value only when the order includes an agreed analytical method and batch report.
Whole-fruit quality is judged together with crushed fruit, frozen juice, clumps and thawed appearance.
Whole-Berry Integrity and Juice Leakage Control
Mulberries are softer than blueberries and other firm berries. We therefore define whole-fruit ratio, crushed-fruit percentage, frozen juice leakage, clumps and free ice instead of relying only on the word whole.
≥95%; broken/crushed ≤5%.
≥90%; broken/crushed ≤8%.
Maximum 3%.
Maximum 3% / 1%.
Choose the Right Frozen Dark Mulberry Grade
| Grade | Concrete Reference | Recommended Application |
|---|---|---|
| Premium Dark Whole | Whole ≥95%; dark ≥95%; Brix ≥15°Bx by lot; broken ≤5% | Retail, fruit cups, dessert topping and premium foodservice |
| Standard Dark Whole | Whole ≥90%; dark ≥90%; Brix ≥11°Bx; broken ≤8% | Yogurt, ice cream, smoothies and bakery |
| 13-17 mm Calibrated | Widest diameter under agreed method | Retail, foodservice and standardized dosing |
| Processing Grade | Brix ≥10°Bx; breakage by approved specification | Juice, puree, jam and sauce |
| Certified Organic | Physical grade plus valid certification and transaction documents | Certified-organic retail and manufacturing |
Processing Grade changes appearance and whole-fruit tolerance. It does not reduce microbiological, residue, traceability or foreign-material requirements.
Pedicel, Leaf and Foreign-Material Control
A natural short pedicel attached to the berry can be accepted under the approved sample. We inspect long stems, leaves and unrelated plant material separately rather than combining all of them into one vague percentage.
Permitted by approved sample.
Proposed max. 1 piece/kg.
Proposed max. 1 piece/5 kg each.
Glass, metal, plastic and stones absent.
Metal detection or X-ray is described only when the selected factory, product and pack format have a validated inspection program.
Inspection equipment supports foreign-material control when validated for the selected order.
Microbiological and Intended-Use Control
The standard product is an ingredient for food manufacturing, foodservice preparation or further processing. Ready-to-eat status requires separate confirmation of the facility hygiene program, microbiological verification, intended use and destination-market requirements.
| Reference Test | Reference Export Limit |
|---|---|
| Total Plate Count | ≤500,000 CFU/g; internal target ≤100,000 CFU/g where agreed |
| Coliforms | ≤1,000 CFU/g; internal target ≤100 CFU/g where agreed |
| E. coli | ≤100 CFU/g; internal target ≤10 CFU/g where agreed |
| Yeast and Mould | ≤100 CFU/g under the reference export specification |
| Salmonella | Absent in 25 g |
| Listeria monocytogenes | Absent in 25 g |
We finalize the test list and limits according to destination, intended use, facility capability and signed customer specification.
Residue and Contaminant Control
Pesticide MRLs and contaminant limits differ by market and can change. We confirm the destination country, relevant commodity category, customer list and laboratory scope instead of presenting an old universal heavy-metal table as a guarantee for every shipment.
Comply with destination-market MRLs and signed specification.
Items and limits confirmed by destination and customer program.
Accredited laboratory report arranged when included in the order.
Jiangsu Raw Material and June-July Crop
The commercial reference origin for this grade is Jiangsu, China, with a June-July harvest and IQF production window. The exporter location in Xiamen is not the raw-material origin.
Because dark-fruited mulberries can belong to different species or cultivars, we confirm farm region, commercial variety, species documentation and crop lot before binding contracts. Frozen inventory supports year-round shipment subject to grade and stock.
Raw-material maturity and defect selection support dark color, Brix and whole-fruit integrity before freezing.

Applications for Premium IQF Dark Mulberries
Premium whole grade; appearance, 13-17 mm sizing, clumps and packaging.
Premium whole; dark color, whole ratio and thawed presentation.
Standard whole; Brix, acidity, dosing and fruit distribution.
Dark whole or natural grade; Brix, color and seed/texture profile.
Standard or Premium; thawing juice, visible fruit and process performance.
Processing Grade; Brix, acidity, color and manufacturing yield.
Thawing and Processing Performance
Dark mulberries naturally soften and release juice after thawing. Results depend on species or cultivar, maturity, berry size, handling, freezing rate, frozen-storage stability and thawing method.
For retail, fruit cups and visible desserts, we recommend current-lot Premium samples and a defined thaw test. Juice, puree and jam processors can compare Standard or Processing Grade without paying for a 95% whole-fruit ratio.
Bulk Packing and Private-Label Options
Bulk
10 kg, 20 lb, 20 kg or 40 lb PE-lined carton.
Foodservice
10×1 kg, 4×2.5 kg or 2×5 kg per carton.
Private Label
227 g, 454 g, 500 g, 1 kg, 2.5 kg or agreed printed packs.
We confirm printed-material MOQ, artwork, barcode, language, ingredient statement, nutrition panel, carton marks and approval timing before production. Loading quantity depends on carton dimensions, pallet use and reefer configuration.
Frozen Storage and Reefer Shipping
We store and transport frozen mulberries at or below -18°C. Before loading, we verify container cleanliness, carton condition, batch, quantity, labels, seal number and product temperature.
The reference MOQ is 10-12 MT or one 20-foot reefer. Loading is approximately 10-12 MT for a 20-foot reefer and 22-24 MT for a 40-foot reefer. Shanghai or Ningbo is selected according to the production and shipment plan, with a normal 15-21 day planning window after deposit and packing confirmation.
Frozen storage, pallet control and carton condition support berry integrity before reefer loading.
Certificate copies and reports must be checked against the selected facility, product scope, market and order.
Certifications and Export Documentation
We review certification availability against the applicable production facility and product scope. Certified organic mulberry is supplied only when the raw material, facility and transaction documents are valid for the order.
Batch Traceability and Inspection Support
We link each commercial lot to raw-material origin, receiving date, production date, processing line, inspection result, laboratory testing, packing record, frozen-storage location and shipment information.
We can coordinate an on-site audit, remote review or third-party pre-shipment inspection under the purchase contract. Generic system evidence illustrates the control method; the final mulberry lot requires its own records.
Pre-shipment inspection can verify product, carton, quantity and loading readiness before release.
