Naringin 98% Powder (Grapefruit Extract)

What is Naringin 98% Powder (Grapefruit Extract)?

Naringin 98% Powder (Grapefruit Extract) is a standardized, crystalline phytochemical monomer raw material designed for structural dietary supplements and functional nutrition。 The core molecular identity features the precise formula C27H32O14 (CASない 10236-47-2, 分子量: 580.53 g/mol). Commercially categorized under grapefruit extract, the active ingredient is sustainably extracted from the immature exocarp of Pomelo (Citrus grandis L.) to guarantee supreme biological yield.

Processed via validated aquatic-ethanol extraction and multi-stage recrystallization, the ingredient provides a minimum 98.0% Naringin content verified via HPLC. The matrix contains zero added excipients, flow agents, or synthetic fillers, preserving the pure crystalline structure of the active bioflavonoid. The refined molecule serves as a critical industrial precursor for advanced downstream derivatives, including the high-intensity alternative sweetener Neohesperidin Dihydrochalcone (NHDC).

For contract manufacturers (CMOs), the refined crystalline grain profile delivers optimal physical stability, completely eliminating the hygroscopic clumping common in lower-assay fruit extracts. The free-flowing material eliminates static agglomeration and powder bridging in automated hoppers, preventing die-sticking and punch surface fouling on high-speed rotary tablet presses. Its high chemical purity ensures reliable dissolution kinetics and matrix compatibility, guaranteeing zero structural separation.

仕様

Quality & Compliance

Global Food Safety Registrations: The processing infrastructure operates under a quality management matrix audited and certified by premium global standards, actively holding BRCGS (Grade A), IFS Food (Higher Level), and US FDA Facility Registration. These baseline manufacturing benchmarks ensure total compliance with corporate vendor qualification audits for international dietary supplement networks.

Dietary Identity and Organic Integrity: Complete traceability and identity purity are verified across global consumer markets, fully backed by active Kosher, Halal, COSMOS Approved, EU Organic, and USDA Organic credentials. The ingredient is strictly certified non-irradiated, ethylene oxide free (ETO-free), and contains zero carriers, fillers, or synthetic anti-caking additives.

Strict Heavy Metal Limits: In absolute compliance with California Proposition 65 and international pharmacopeia criteria, analytical batch release thresholds enforce Pb ≤ 0.5 ppm, As ≤ 0.5 ppm, Cd ≤ 0.2 ppm, and Hg ≤ 0.1 ppm. Quantitative analysis is conducted via validated ICP-MS protocols to pass strict heavy metal breakdowns during customs clearance.

Pesticide and Solvent Controls: Multi-residue screening systematically satisfies Regulation (EC) No 396/2005 for European food safety pesticide residue boundaries. The purification loop utilizes specialized alcohol-water recrystallization, with residual solvent levels locked at Ethanol ≤ 5,000 ppm, fully conforming to USP <467> Class 3 specifications.

Key Advantages

Excellent Powder Flowability and Kinetics: The refined crystal grain geometry of the ingredient creates a highly uniform bulk density matrix (0.35 g/mL - 0.50 g/mL). This optimized density distribution establishes a Hausner ratio under 1.30, ensuring frictionless mass flow and zero mechanical bridging inside feed hoppers during automated blending.

Hygroscopic Stabilization and Moisture Resistance: Unlike crude fruit powders, this multi-stage recrystallized single monomer eliminates sticky botanical pectin and free sugars. The low moisture retention profile prevents static agglomeration and atmospheric moisture absorption, successfully eliminating tooling surface caking, punch fouling, and tablet lamination on high-speed rotary presses.

Thermal Resilience and Formula Stability: The fully bound crystalline chemical framework features an advanced degradation threshold, surviving extreme thermal environments with zero molecular shifting or active breakdown. The ingredient remains chemically inert when subjected to high-shear blending and sub-pasteurization processing, maintaining a stable, standardized minimum 98.0% Naringin content throughout manufacturing.

Advanced Formula Excipient Compatibility: Due to the pristine yellow-white flavanone glycoside structure, the unbuffered material exhibits neutral chemical reactivity with diverse downstream matrices. It prevents cross-linking degradation of HPMC capsule shells and maintains zero negative interaction with blending excipients, active vitamins, or complex co-enzymes, ensuring excellent long-term batch uniformity.

Applications

Solid Dosage Encapsulation (Hard-Shell Capsules): The crystal particle profile (100% through 80 mesh) optimizes mass flow parameters on automated rotary encapsulation machinery. The predictable loose bulk density (0.35 g/mL - 0.50 g/mL) ensures clean cavity packing and exceptional fill weight uniformity within standard HPMC or gelatin capsule shells, maximizing machine running efficiency.

Ready-to-Mix (RTM) Powders and Stick Packets: Free of hygroscopic botanical pectins and plant sugars, the crystalline monomer prevents flavor carrier clumping and moisture absorption in instantized dietary supplement drink mixes. The odorless, low-ash (≤ 0.5%) characteristics guarantee immediate dispersion without localized sedimentation, maintaining high clarity and taste stability in beverage formulations.

Direct Compression Tableting (Solid Oral Dose Blends): The refined crystalline matrix exhibits strong plastic deformation and compressibility indices under low mechanical forces, avoiding common industrial defects such as tablet capping, laminating, or tablet face cracking. It satisfies strict physical hardness thresholds while maintaining a predictable tablet disintegration profile compliant with USP and EP regulatory standards.

Industrial Substrate Synthesis (Downstream NHDC Production): Functioning as a high-purity regulatory-grade precursor, the ≥ 98.0% active Naringin core is highly optimized for catalytic ring-opening and hydrogenation processing loops. This standardized purity guarantees maximum molecular conversion rates and consistent batch yields on industrial synthesis lines for the alternative sweetener Neohesperidin Dihydrochalcone (NHDC).

Technical FAQ

Q1: How does the bulk density and grain distribution profile of Citrus grandis L. extract prevent mechanical bridging and fill weight variations during automated hard-shell encapsulation?
A1: The crystalline grain geometry where 100% of particles pass through an 80 mesh screen yields a predictable bulk density of 0.35 g/mL - 0.50 g/mL and a tapped density of 0.50 g/mL - 0.65 g/mL. This delivers a Hausner ratio under 1.30 monitored via USP <616> Method I, eliminating powder consolidation inside feed hoppers. This rheological control ensures frictionless mass flow and uniform die cavity filling across automated high-speed encapsulation lines.

Q2: What manufacturing controls are implemented during the purification of anhydrous crystalline naringin to eliminate high-speed tableting defects like punch fouling and tablet lamination?
A2: The substance undergoes an alcohol-water recrystallization that locks Loss on Drying at <= 5.0% evaluated under USP <731> and Ash Content at <= 0.5% under USP <561>. Removing sticky botanical pectins eliminates static charge buildup and capillary moisture bridges under high compression forces. This precise control prevents tooling surface caking and tablet capping on rotary presses while maintaining USP/EP compliant disintegration profiles.

Q3: Why is an assay threshold of minimum 98.0% active naringin core required for downstream industrial substrate synthesis, and how is it qualified to clear international regulatory audits?
A3: An assay of >= 98.0% on anhydrous basis determined via HPLC is required to guarantee maximum molecular conversion rates during catalytic hydrogenation into Neohesperidin Dihydrochalcone (NHDC). To clear global supply chain audits, this regulatory-grade grapefruit bioflavonoid enforces Pb <= 0.5 ppm, As <= 0.5 ppm, Cd <= 0.2 ppm, and Hg <= 0.1 ppm via validated ICP-MS (USP <232>/<233>). This rigorous purity validation ensures compliance clearance under California Proposition 65 and BRCGS Grade A standards.
