Discover our comprehensive range of high-efficacy botanical extracts engineered to global pharmaceutical and nutraceutical standards.
Exploring the active components, scientific processing pathways, and raw-material properties of bulk *Sesamum indicum* supply chains.
Black Sesame (Sesamum indicum) seeds represent one of the most chemically complex oilseeds in botanical nutrition. High-performance liquid chromatography (HPLC) profiles verify that its active therapeutic properties reside primarily in its specific lignan structures—principally Sesamin, Sesamolin, and Sesamol. These lipid-soluble phytoestrogens provide strong antioxidant defenses, promote cardiovascular system health, and help inhibit lipid peroxidation in functional applications.
For global enterprises sourcing raw materials, the concentration of active constituents determines product potency. In addition to lignans, our premium black sesame crops are rich in essential unsaturated fatty acids, including oleic and linoleic acids, along with calcium, iron, magnesium, and vitamin E. Sourcing directly from verified Chinese agriculture zones ensures access to raw seeds with optimized chemical profiles.
How Chinese raw material bases and modern processing facilities deliver quality and cost advantages to the international market.
By coordinating closely with local farmers, UniCare manages dedicated black sesame planting areas strictly aligned with GACP guidelines. This direct connection limits contamination risks, supports pesticide-free farming practices, and guarantees raw material origin tracing for every production batch.
Equipped with modern optical sorting technologies, Buhler color sorters, and X-ray scanners, Chinese factories effectively remove physical impurities like glass, stones, dust, and foreign organic matter to protect the purity of the raw inputs.
Our extraction facilities process substantial volumes daily. Automated, continuous-flow production lines allow us to handle large-volume orders without sacrificing ingredient quality or batch-to-batch uniformity.
Entering overseas markets like the United States, EU, Japan, and Korea requires adhering to rigorous regulatory guidelines. At UniCare, we provide detailed regulatory documentation to support custom clearance, product registration, and compliance tracking.
We specialize in monitoring heavy metals (including Lead, Arsenic, Mercury, and Cadmium), pesticide residues (tested via GC-MS/MS), and minimizing Ethylene Oxide (EtO) risks. This careful testing process helps our products meet or exceed the standards set by US FDA, EFSA, and international pharmacopoeias.

Our central laboratory covers a large layout and is qualified by CNAS. It is staffed by professional chemists and analysis specialists. Important testing instruments include:
From seed breeding research to raw material extraction, ensuring complete vertical integration.
UniCare invests 10% of our annual net profit in research and development. In addition to optimizing and developing the existing natural plant extraction processes, we have established a professional R&D department focused on natural fermentation products. By increasing investment in natural fermentation solutions, we aim to break through traditional extraction limits and explore new possibilities for the industry.
We work in close cooperation with Beijing University of Chemical Technology in the field of fermentation, jointly developing and scaling up raw materials for pharmaceuticals, cosmetics, and natural health products into mass production.
To control raw material quality effectively, we developed a procurement system that traces materials back to individual planting fields. The storage of raw materials follows our quality management process, where active ingredients, moisture, ash, heavy metals, and pesticide residues are inspected upon arrival.
For key products, UniCare cooperates with growers to establish dedicated planting bases for Ginkgo leaf, Epimedium, Phellodendron, and Olive leaf. Select bases are managed according to GACP models. We also partner with seed research firms to develop high-yield crop varieties through hybrid selection and optimized cultivation to improve raw material concentration.
Understanding what global buyers prioritize and where the market is moving.
Global procurement teams prioritize purity and safety. Main criteria include zero-tolerance policies for Salmonella, low heavy metal levels (Pb < 0.2ppm, As < 0.1ppm), and minimal microbial counts. Providing certified batch COAs is essential for supply chain approval.
Consumers increasingly look for clean-label, non-GMO, and organic options. Meeting these expectations requires clean extraction methods, zero synthetic carriers, and transparent raw material sourcing, which is supported by our detailed documentation.
As plant-based diets grow in popularity, demand for plant proteins and high-stability oils has risen. Our black sesame materials are optimized to preserve nutrient integrity and functional performance in food and beverage formulas.
How manufacturers formulate our high-grade black sesame derivatives across different industries.
Formulated into capsules and tablets standardized to high Sesamin percentages to support liver function, metabolic balance, and cardiovascular health.
