HPLC-verified purity profiles, customizable mesh density, and low-solvent residue solutions formulated for Japanese dietary supplement manufacturers.
Analyzing why Nagoya and Aichi Prefecture represent Japan’s fastest-growing corridor for ocular health, anti-fatigue functional beverages, and high-purity xanthophyll carotenoid imports.
Nagoya’s vast network of R&D engineers and precision assembly specialists faces prolonged VDT (Visual Display Terminal) strain. Local nutraceutical brands are rapidly formulating softgels and jelly sticks combining Lutein (10mg–20mg) with Zeaxanthin at a 5:1 bio-identical ratio to support macular pigment optical density (MPOD) and reduce visual fatigue.
Under the CAA framework, Japanese importers require rigorous clinical literature, batch stability logs, and precise analytical testing (HPLC). Raw material supplied to Nagoya factories must exhibit strictly controlled residual solvents (ethanol extraction over acetone/hexane) and clear non-GMO, pesticide-free documentation.
Traditional oil-soluble lutein paste is unsuitable for Nagoya’s expanding functional RTD tea and wellness shot market. We supply cold-water dispersible (CWS) beadlets (5% to 10% assay) manufactured via spray-drying microencapsulation that resist sedimentation and clarity degradation across shelf life.
Selecting the optimal carotenoid substrate based on dosage form, bio-accessibility, and process stability under Japanese manufacturing parameters.

Operating dedicated plant extract synthesis and purification facilities since 2014, backed by full batch documentation and regulatory audit readiness.
Our extraction, crystallization, and drying lines operate under strict GMP, ISO9001, ISO22000, HALAL, and KOSHER systems. Every batch intended for the Japanese market undergoes rigorous multi-stage testing including heavy metal ICP-MS screening (Lead <0.5ppm, Arsenic <0.5ppm, Cadmium <0.2ppm, Mercury <0.1ppm).
To meet Japan's stringent organic solvent residual standards, RAAG Biotech employs supercritical CO2 fluid extraction and membrane purification columns. This ensures target carotenoids (Lutein, Zeaxanthin) and flavonoids (Quercetin) are isolated without residual chlorinated solvents or acetone traces.
From non-GMO Tagetes erecta L. (Marigold) flower fields to raw resin saponification and finished crystal powder, every drum is linked to a batch record sheet detailing harvest region, drying conditions, pesticide screening (GC-MS/MS 400+ panel), and retained quality control samples stored for 36 months.
Clear, direct responses addressing customs clearance, import testing, documentation packages, and logistics via the Port of Nagoya.
Every commercial invoice and packing list is paired with a batch-specific Certificate of Analysis (COA by HPLC), Material Safety Data Sheet (MSDS), Technical Data Sheet (TDS), Flow Chart, Non-GMO Statement, Allergen Declaration, and Pesticide Residue Test Report compliant with the Japanese Food Sanitation Act.
We utilize food-grade ethanol reflux extraction or solvent-free Supercritical CO2 extraction. Total residual ethanol is strictly controlled below 1,000 ppm (far below international ICH guidelines), with zero detectable class 1 or class 2 toxic solvents, ensuring smooth entry through Port of Nagoya Customs Quarantine.
In-stock powders ship from our primary warehouse within 3 to 5 business days. Sea freight transit from major Chinese ports (Shanghai/Ningbo) to Port of Nagoya typically takes 3 to 5 days, while air express (DHL/FedEx) delivers directly to Nagoya Airport (NGO) in 2 to 4 days.
Yes. We tailor particle size from standard 80 mesh down to micronized 320 mesh for rapid dissolution. For microencapsulated CWS powders, we offer custom carrier matrices including Gum Arabic, Maltodextrin, Modified Starch, or clean-label Rice Starch to align with your brand's label claims.
Our standard MOQ for commercial Lutein Free Powder and Quercetin Extract is 1 kg. For custom-engineered microencapsulated beadlets, liposomes, or private specifications, the pilot batch MOQ starts at 25 kg, with complimentary 20g–50g pre-shipment lab samples provided for QA verification.
Yes, we formulate synergistic pre-mixes matching clinical gold standards (e.g., Lutein 10mg : Zeaxanthin 2mg or 20mg : 4mg) in oil, beadlet, or dry powder formats, complete with dual-assay HPLC batch certificates.
