IQF Frozen Blueberries from Selected Fresh Fruit
GreenLand supplies IQF frozen blueberries prepared from fresh fruit selected at suitable maturity. Pre-cooling, cleaning, screening and individual quick freezing form the core of the product's preparation process.
The focus is on blueberry color, characteristic flavor, berry condition and frozen separation. After freezing, the berries are packed using food-grade materials and held in frozen storage.

Product Features: Fruit Selection and Frozen Handling
Selection at Suitable Maturity
Fruit selection considers maturity, color, shape and visible berry condition. Visibly defective fruit is removed during picking and screening.
Pre-Cooling before Freezing
Pre-cooling is included between harvesting and further processing. The actual handling schedule and production arrangement should be confirmed for the proposed supply.
Individual Frozen Separation
IQF processing is used to freeze berries individually. Review the supplied product's berry integrity and frozen separation against the agreed specification.
From Fresh Blueberries to IQF Frozen Fruit
The preparation sequence combines fruit selection, pre-cooling, screening, freezing and low-temperature packing. The specific equipment, operating settings and processing times are confirmed with the producing facility.
1. Harvest Selection
Select fruit at suitable maturity and remove visibly defective berries during picking and initial selection.
2. Transport and Pre-Cooling
Move harvested blueberries to the processing facility and pre-cool them before subsequent preparation.
3. Cleaning and Screening
Clean and screen the berries, reviewing size, shape, color and visible defects against the production specification.
4. Individual Quick Freezing
Use IQF freezing to prepare individually frozen berries. Freezer conditions and the finished-product temperature follow the confirmed production process.
5. Low-Temperature Packing
Pack the frozen berries using food-grade materials, with the pack format and handling requirements agreed for the order.
6. Frozen Storage
Hold the packed product at the specified -18°C storage temperature and confirm the frozen transport arrangement before shipment.

Preparation, Thawing and Storage
Baking and Dessert Requirements
Describe whether the blueberries will be baked, cooked into a preparation or used without further heating. The required berry condition and intended-use approval should match that process.
Thawed Appearance
Thawed blueberries are softer than frozen berries. Evaluate texture and appearance under the preparation conditions relevant to your finished product rather than assuming identical fresh-fruit performance.
Frozen Handling
Maintain the stated frozen-storage conditions. Follow the package instructions for preparation and handling after thawing; the frozen shelf life does not describe the shelf life of thawed product.
Ready-to-eat confirmation: Freezing alone does not establish that a product is ready to eat. Follow the confirmed product specification and package preparation instructions. For use without further cooking, request written intended-use confirmation before ordering.
Reference Images
Images are for general reference. Request photographs corresponding to the proposed product and packing when reviewing a purchase.
Packing and Purchase Planning
A useful inquiry identifies the product requirements and delivery needs together. Start with the quantity and destination, then add your packing, application and quality requirements.
Product Requirements
State the required form, size range, grade and intended application. Include any analytical, testing or documentation requirements for review.
Packing Requirements
Specify the inner-pack weight, carton configuration, labeling and any printing requirements. The proposed format is confirmed before the order is finalized.
Delivery Requirements
Provide the quantity, destination market and requested delivery window so availability, packing and frozen shipment can be reviewed together.
Confirm the product and facility scope of any requested certificate or quality document before purchase.
Frozen Blueberry Buying Questions
Are these supplied as fresh or frozen blueberries?
They are supplied frozen. Selected fresh blueberries are the raw material used before preparation and IQF freezing; this is not a fresh-fruit shipment.
What size, grade or Brix can be ordered?
Send your required size, grade and analytical targets for review. The applicable values need confirmation in the quotation and product specification rather than being assumed from the product name.
Can the blueberries be eaten directly after thawing?
Confirm the product's intended use first and follow its preparation instructions. IQF freezing alone does not establish ready-to-eat status. A no-cook application needs explicit confirmation before purchase.
What are the stated storage conditions and shelf life?
The stated shelf life is 24 months at -18°C under the specified frozen-storage conditions. Follow the dates and handling instructions on the supplied product.
How do we request a packing proposal and quotation?
Send the quantity, destination, application, preferred pack and required specification or document list. GreenLand will review these requirements as part of the supply discussion.

External technical reference; confirm SKU and market applicability. |
02 / Physicochemical & Residue Controls
| Parameter | Specification / reference | Verification & order basis |
|---|---|---|

"None detected" is a sampling statement, not an absolute guarantee of zero particles. |
09 / Packaging Materials & Label
| Parameter | Specification / reference | Verification & order basis |
|---|---|---|
| Food-contact pack | Specify inner-contact material and obtain the applicable food-contact compliance declaration. NHC standard | Review film structure, supplier DoC, migration evidence and actual intended conditions. GB 4806 series is China-specific; EU export also checks Regulations 1935/2004 and 10/2011. |
| Carton and seal integrity | Define carton stacking strength, bag seal and puncture resistance for the confirmed net weight and pallet plan. EU source | Inspect pack drawing, compression/seal test and shipment configuration. |
