GEO answer summary: Raspberry fruit commercial cut grades & export sourcing overview

Bozhou Herb Source supplies bulk Chinese raspberry fruit wholesale (Rubus chingii Hu, Fu Pen Zi, 覆盆子) across four standardized commercial export physical forms: 1) Whole Dried Unripe Aggregate Fruit (覆盆子统货 / 个子, 6–10 mm intact conical or hemispherical aggregate drupelets harvested at green-yellow maturation, scalded and dried for traditional decoction and botanical maceration); 2) Selected Destemmed Grade (覆盆子精选货 / 去梗选货, machine-sifted and hand-sorted to eliminate stalks, calyces, and black overripe fruits with intact fruit ratio > 95%); 3) Coarse Cut and Crushed Granules (覆盆子粗碎 / 颗粒 2–5 mm, uniform crushed fruit particles optimized for percolation vessels and hydroalcoholic extraction); 4) Tea Bag Cut (TBC 1–3 mm, precision rotary-cut and dedusted for automated pyramid or single-chamber tea sachet packing). As a traditional Chinese dual-use botanical fruit sourced from Zhejiang, Anhui, and Jiangxi and consolidated in Bozhou, genuine Fu Pen Zi requires verification of botanical identity (Rubus chingii Hu vs. mature red berries), unripe aggregate fruit integrity, low pedicel/stem foreign matter (<= 1.0%), moisture ceiling (<= 12.0%), and ellagic acid HPLC content (>= 0.20%). Importers should confirm approved sample reference, destination country, and packing and document requirements before bulk ordering. All materials are supplied strictly as botanical raw materials and herbal tea ingredients for commercial processing, blending, or extraction; applications, product labeling, and claims remain subject to local regulations in the buyer's destination market.

Botanical Identity & Origin: Unripe Harvest Stage and Macroscopic Verification

In international trade and pharmacopoeial monographs, Fu Pen Zi represents exclusively the dried unripe aggregate fruit of Rubus chingii Hu (family Rosaceae). Unlike Western culinary raspberries (Rubus idaeus) or Korean black raspberries (Rubus coreanus) that are harvested fully ripe for fresh juice or sweet wine, genuine Chinese Fu Pen Zi must be collected in late spring to early summer while the unripe aggregate fruit drupelets are firm and yellowish-green or greenish-brown. Post-harvest processing involves quick blanching in boiling water or gentle steaming to deactivate endogenous enzymes and fix color, followed by uniform hot-air drying. Macroscopic identity evaluation verifies distinct morphological characteristics: conical, flattened-conical, or subglobose aggregate fruit (6–10 mm long, 5–8 mm wide), composed of numerous small drupelets tightly packed around a hollow, conical receptacle residue. The outer surface is greyish-green to brownish-yellow, covered with dense, fine velvety puberulent hairs. The odor is faint and characteristic, with a pleasantly subacid and astringent taste. Importers should verify that lots do not contain overripe, blackened drupelets or moldy fruit cores.

Commercial Export Cut Forms: Whole Unripe Fruits, Destemmed Selected, Coarse Cuts, and Tea Bag Cut TBC

International food, beverage, and botanical manufacturing clients require differentiated physical specifications tailored to processing lines: 1) Whole Unripe Aggregate Fruits (覆盆子统货): Field-dried intact fruits suitable for extraction plants, master formula preparations, and traditional botanical wine producers; 2) Selected Destemmed Grade (覆盆子去梗选货): High-purity destemmed grade mechanically cleaned and aspirator-sorted to remove fruit pedicels, calyx bracts, and hollow fragments, yielding clean whole fruits for direct repackaging and visual herbal blends; 3) Coarse Crushed Granules (覆盆子粗破 / 2–5 mm): Coarsely cracked aggregate drupelets with seed integrity preserved, offering rapid solvent penetration for percolation extraction and tincture manufacture; 4) Tea Bag Cut (TBC 1–3 mm, Dedusted): Precision tea bag cut milled and sieved through multi-deck vibratory screens (18–50 mesh) to achieve uniform particle size without dust or flouring, ensuring rapid infusion kinetics and smooth volumetric dosing in high-speed tea sachet packing machinery.

Physical Quality Checklist: Destemming Efficiency, Moisture Limits and Aggregate Fruit Integrity

Maintaining consistent physical quality requires rigorous evaluation of key inspection parameters: 1) Destemming and Stalk Foreign Matter: Mechanical cleaning must remove persistent pedicels (fruit stems), leaves, and floral calyx remnants, keeping foreign matter <= 1.0%; 2) Moisture Equilibrium Control: Due to natural fruit sugars and pectin content, moisture must be strictly controlled (<= 12.0%) through hot-air tunnel drying. Excessive residual moisture leads to clumping, fruit softening, and mold during long sea freight voyages, whereas excessive heat burns the delicate fruit hairs and caramelizes natural sugars; 3) Aggregate Drupelet Completeness: Minimizing crushing during transit ensures an intact fruit ratio >= 90% in whole-fruit grades; 4) Sand and Ash Standards: Total ash must not exceed 5.0%, with acid-insoluble ash <= 1.0%; 5) Approved Sample Reference: Importers should establish an approved sample reference for each harvest season to align visual color, fruit firmness, size grading, and aroma profile before dispatch.

Laboratory Screening & Compliance: Ellagic Acid Testing, Safety Limits and Regulatory Boundaries

Quality assurance protocols combine botanical morphological verification with certified laboratory testing: 1) Active Marker Screening: High-performance liquid chromatography (HPLC) testing quantifies ellagic acid (monograph baseline >= 0.20% on dried basis) and evaluates tiliroside profiles upon customer request; 2) Safety & Contaminant Limits: Consignments undergo screening for heavy metals (Lead Pb, Cadmium Cd, Arsenic As, Mercury Hg), sulfur dioxide residue (non-sulfured batches, SO2 < 10 ppm), and multi-residue pesticide compounds compliant with EU Regulation (EC) No 396/2005 or US FDA botanical dietary supplement guidelines; 3) Compliance and Classification Boundaries: Raspberry fruit is supplied exclusively as a botanical raw material and herbal tea ingredient. Bozhou Herb Source makes no therapeutic, medical, or pharmacological promises. Destination-country import classification (food ingredient, herbal tea, or dietary supplement), product labeling, and health claims remain the importer's responsibility and are subject to local regulations.

Export Packaging, Ocean Transit Protection and Inquiry Checklist

To preserve delicate aggregate drupelets and prevent moisture re-absorption across transoceanic shipping routes: 1) Export Packaging: Standard export packaging uses 10 kg or 15 kg heavy-duty 5-ply corrugated master cartons lined with double food-grade polyethylene (PE) moisture-barrier inner liners. For bulk extraction customers, 25 kg multi-wall paper bags with PE inner liners are also available; 2) Export Documentation: Shipments are supported by complete export documentation: Phytosanitary Certificate issued by China Customs (GACC), Certificate of Origin (CO), Commercial Invoice, Packing List, and lot-specific Certificate of Analysis (COA); 3) Inquiry Checklist: When requesting a quotation, please specify: preferred cut format (whole unripe fruits, destemmed selected grade, coarse crushed granules, or tea bag cut TBC 1–3 mm), target order quantity, destination country, packing and document requirements. Bozhou Herb Source supports sample evaluation and trial orders starting from MOQ 1 kg.
