Basic Product Information

Premium Sesamin by SRBio – High-Purity Lignan from Sesame Seed

SRBio Sesamin is a high-purity natural lignan extracted from the seeds of Sesamum indicum (sesame), one of the richest known sources of this bioactive compound. Sesamin is a furofuran lignan, a unique class of phytochemicals found almost exclusively in sesame seeds and sesame oil, where it serves as a key contributor to the oil‘s remarkable oxidative stability. The sesamin content in raw sesame seeds is naturally low—typically 0.5%–1.2%—making advanced extraction and purification technologies essential for producing high-purity sesamin isolates.

Produced using patented CO₂ supercritical extraction technology followed by precision chromatography, SRBio Sesamin achieves industry-leading purity of 98%–99.5% (HPLC-verified), significantly exceeding the typical industry standard of 90%–95%. This solvent-free, green extraction process preserves the molecular integrity of sesamin while eliminating toxic solvent residues. The result is a clean, high-purity product ideal for premium nutraceutical, functional food, and cosmeceutical formulations.

Sesamin has been the subject of extensive scientific research over the past three decades. Studies have demonstrated its potent antioxidant activity, ability to modulate fatty acid metabolism, vitamin E-sparing effects, and support for healthy liver function. As one of the most thoroughly studied sesame lignans, SRBio Sesamin offers manufacturers a science-backed ingredient with proven stability and consistent quality across every batch.

Manufacturing & Quality Excellence

• Raw material sourcing: Ethically-sourced Sesamum indicum seeds from Xinjiang, China, selected for high sesamin content and grown under non-GMO, pesticide-free conditions. DNA authentication ensures no adulteration with S. alatum or other species.

• Patented extraction technology: CO₂ supercritical extraction combined with multi-stage chromatography yields 98%+ sesamin purity without the use of toxic organic solvents. This green technology preserves the natural molecular structure of sesamin while eliminating solvent residue concerns.

• Customizable specifications: Available in multiple potency grades ranging from 10% to 98% sesamin content, allowing manufacturers to select the ideal concentration for their specific formulation needs and cost targets.

• Quality testing: Each batch undergoes rigorous quality control including HPLC assay for sesamin content, chiral purity testing to exclude inactive isomers, ICP-MS heavy metal screening (Pb <0.1 ppm, As <0.05 ppm), GC-MS residual solvent analysis (none detected), and microbial testing (TPC <100 CFU/g, zero pathogens).

• Certifications: Our facility complies with cGMP, ISO 22000, FSSC 22000, and HACCP standards. FDA Drug Master File (DMF) on file. Kosher, Halal, and Non-GMO certifications available upon request. Allergen statement and GMO-free declaration provided with each shipment.

Core Product Advantages

1. Industry-leading purity — 98% sesamin content (HPLC-verified), significantly exceeding the industry average of 90%–95%. Impurities such as sesamolin and sesaminol are controlled below 0.5%.

2. Superior antioxidant activity — Sesamin is a potent scavenger of free radicals (ROS and RNS), mitigating oxidative stress by donating electrons to reactive species and preventing cellular damage and lipid peroxidation. It also upregulates endogenous antioxidant enzymes including SOD, catalase, and GSH-Px.

3. Vitamin E-sparing effect — Sesamin inhibits vitamin E metabolism, resulting in increased circulating levels of γ-tocopherol and γ-tocotrienol. Oral ingestion of 100–150 mg of sesamin is sufficient to preserve vitamin E levels in the body, making it a valuable co-ingredient in antioxidant formulations.

4. Metabolic support — Research indicates sesamin modulates fatty acid metabolism and inhibits cholesterol absorption and biosynthesis, supporting healthy lipid profiles and liver function in connection with alcohol metabolism.

5. Low MOQ with flexible options — Minimum order quantity starts at just 1 kg, ideal for R&D projects, clinical trials, and small-batch production. Annual production capacity of 5,000 kg (expandable to 15,000 kg) supports seamless scaling from laboratory to commercial volumes.

6. Patented green extraction — CO₂ supercritical extraction + chromatography delivers 99.5% purity without toxic solvents, ensuring a clean, sustainable, and structurally intact product.

7. End-to-end traceability — Blockchain-tracked transparency with QR code access to seed origin (farm GPS coordinates), extraction batch logs, and third-party lab reports from Eurofins/SGS.

8. Excellent formulation compatibility — Available as white crystalline powder (adjustable mesh size up to 200-micron) compatible with capsules, tablets, oil suspensions, water-dispersible powders, and complex blends with other nutraceuticals.

Physical & Formulation Properties

Application Benefits

• Dietary supplements
  Sesamin is widely used in liver health formulations (200–400 mg/day, often synergized with milk thistle), weight management products (300 mg sesamin + 100 mg CLA supported by clinical data on fat oxidation), and antioxidant blends (2%–5% inclusion in premium multivitamins).

• Functional foods & beverages
  The clean, neutral taste profile allows seamless integration into functional food matrices. Oil suspensions (10%–50% sesamin) and water-dispersible powder formats are available for beverages, nutrition bars, and ready-to-mix drink powders.

• Cosmeceuticals
  Sesamin is valued in topical formulations for its UV-protective properties (inhibits MMP-1 collagenase) and anti-aging benefits (upregulates Nrf2 pathway). Suitable for serums, anti-aging creams, and sun protection products.

• Animal nutrition
  In aquaculture feed, 0.1% sesamin inclusion has been shown to enhance shrimp survival rates by 15%. For dairy cattle, sesamin supplementation reduces somatic cell count in milk.

• Sports nutrition
  Emerging research positions sesamin as a supportive ingredient for fat oxidation and metabolic efficiency, making it attractive for weight management and sports performance products.
