Product Description

Black pepper extract is derived from the dried mature fruits of Piper nigrum L. through modern extraction technology, enriched with piperine and other active compounds. The extract is a uniform light yellow to white fine powder, non-caking, with a strong characteristic pungent aroma of black pepper and no off-odor. It is soluble in organic solvents such as ethanol and methanol, with limited solubility in water. The resulting solution is clear, without significant precipitation, meeting solubility requirements for various applications. When stored under recommended conditions (cool, dry, light-proof, sealed), the product remains stable for 24 months with less than 5% variation in piperine content, ensuring consistent quality. Production follows GMP standards with 12 quality control checkpoints, including raw material identification, heavy metal screening, microbial tests, in-process monitoring, active ingredient analysis, and solvent residue testing. This ensures safety, purity, and efficacy for applications in food, dietary supplements, cosmetics, and pharmaceuticals.

Technical Analysis

1. Extraction Technology

The extract is produced using a combined supercritical CO₂ extraction + molecular distillation purification process:

- Supercritical CO₂ Extraction: Uses CO₂ under supercritical conditions (35–40℃, 20–30 MPa) to extract actives without toxic solvents. Low temperature protects heat-sensitive compounds, improving retention rate of piperine to over 98% (vs. ~85% by traditional ethanol reflux). CO₂ is recyclable, with 30% higher raw material utilization.

- Molecular Distillation Purification: Under high vacuum (≤1 Pa) and low temperature (80–100℃), molecular distillation separates actives from impurities (oils, pigments, sugars). Piperine content is enriched from 40–50% to over 95%, with high purity and low impurities (ash ≤5%, moisture ≤5%).

2. Piperine Characteristics

- Molecular Formula: C₁₇H₁₉NO₃, MW 285.34
- Structure: Contains a benzodioxole moiety and conjugated double bonds, giving strong lipophilicity. Enhances intestinal absorption of fat-soluble nutrients (vitamins A, D, E, K, curcumin, astaxanthin). Research shows it increases curcumin bioavailability over 20-fold.
- Stability: Stable between pH 3–9; under 121℃ for 30 minutes, loss ≤3–5%. Heat-stable for food processing. Light-sensitive, requires storage away from light.

Quality Control

- Raw Materials: Verified by Near-Infrared Spectroscopy (NIRS) to prevent adulteration; ICP-MS ensures heavy metals within safe limits (Pb ≤0.1 mg/kg, As ≤0.05 mg/kg).
- In-Process Control: Online HPLC for piperine content and real-time moisture monitoring.
- Finished Product Testing: Triple testing (HPLC for piperine, GC for solvent residues, microbial limits). Only fully compliant batches are released with COA.

Product Advantages

High Purity & Activity – Piperine up to 98%, higher than standard extracts (60–80%). Retains bioactivity, enhancing nutrient absorption efficiency by 15–20%.

Safe & Solvent-Free – Only food-grade CO₂ is used; no toxic solvent residues. Meets GB 2762 (contaminants) and GB 4789 (microbiology) standards.

Excellent Stability & Versatility – Stable under pH 3–9 and 80–121℃, suitable for baking, sterilization, beverages, and more. Fine powder form, easy to blend into diverse formulations.

Cost-Effective – Efficient extraction increases raw material utilization by 30%. Higher purity means lower dosage needed, reducing downstream costs.

Regulatory Compliance – Produced under ISO 9001, ISO 22000, and GMP certifications. Provides COA, third-party test reports, and manufacturing licenses for regulatory submission.
