High-purity raw ingredients verified under international GMP, ISO, and Organic protocols.
Unlocking the power of plant-based lipids through sustainable agriculture, structural innovation, and highly optimized extraction protocols.
Flax (Linum usitatissimum) serves as one of the oldest cultivated crops globally. Northern China, particularly regions like Inner Mongolia, Gansu, and Ningxia, provides the optimal micro-climate—rich soil, long sunshine hours, and significant temperature swings—vital for producing seeds rich in Alpha-Linolenic Acid (ALA). Cold-climate agricultural mastery translates into higher fatty acid yields and superior nutrient stability.
Standard solvent extraction methods degrade sensitive Omega-3 double bonds. Leading Chinese factories implement state-of-the-art cold-pressing techniques maintained strictly below 45°C. By deploying a nitrogen gas blanket over the pressing chamber, our manufacturers shield the active oil from oxidation, keeping the acid value low and the sensory profile clean and nutty.
Omega-3 fatty acids are highly susceptible to rancidity. Advanced stabilization frameworks combine food-grade natural mixed tocopherols and rosemary extract to dramatically extend the shelf life of bulk oil. Furthermore, light-impermeable steel containers filled with high-purity nitrogen prevent photochemical and atmospheric degradation during export voyages.
Nanjing Tong Rui Bio-Tech Co., Ltd. (TRB) has been a leading Chinese manufacturer and exporter of high-grade herbal extracts, active plant lipids, and natural derivatives for more than 20 years.
TRB acts as a technology-based enterprise combining fundamental research, modern agricultural extraction development, industrial-scale production, and global supply chain services. Our product portfolio spans across Herbal extracts, Sweeteners, Nootropics, Vegetable & Fruit Juice powder, Essential oil, and Bee Products.
Driven by rapid development and dedicated service in the plant extract sector over the years, we are honored to announce that TRB has been awarded the 2026 "Global Biotechnology and Life Sciences Award" - ''Best Global Herbal Extract Provider 2026''.
To support international buyers, TRB runs three distinct modern manufacturing plants. One specializes in herbal extract extraction, another handles high-purity bee products, and the third processes premium animal-derived health extracts. All facilities conform to strict global compliance audits and hold a comprehensive suite of certificates: GMP, ISO, HACCP, ORGANIC, FDA, HALAL, and KOSHER Certificates.
Engineering trust through verification, scale, and multi-national execution.
How our advanced manufacturing plants ensure the high purity and structural integrity of Linoleic & Alpha-Linolenic Acid.
We source non-GMO flax seeds from audited agricultural collectives. High grain density, low moisture levels, and clean sorting eliminate foreign materials before pressing.
Single, low-temperature mechanical pressing. Temperature checks ensure cold-pressed processing parameters do not trigger thermal polymerization.
Removing wax particles and raw fibers using physical plate filters and low-temperature dewaxing systems. No synthetic chemical clarifying agents are added.
Flushing storage tanks and final packaging with nitrogen gas, achieving headspace oxygen levels below 2% for maximum shelf-life safety.
Bridging the gap between agricultural supply and global market innovations across diverse consumer sectors.
As the cleanest vegan source of Omega-3, Flax Seed Oil is formulated into liquid supplements, softgel capsules, and dietary emulsions. The rising shift away from marine-based fish oil due to environmental contaminants makes cold-pressed plant lipid alternatives highly desirable for cardiovascular and cognitive formulations.
From fortifying dairy products to stabilizing functional beverages, Flax Seed Oil offers rich texture and a heart-healthy lipid profile. It is also a staple in premium veterinary feeds for horses and dogs, supporting skin elasticity, coat shine, and joint function.
Thanks to its anti-inflammatory properties, cosmetic-grade flax seed oil is utilized as a natural emollient. It deeply moisturizes the skin barrier, reduces redness, and is easily integrated into anti-aging creams, body balms, and hair treatment serums.
To address the natural limitations of oil oxidation and formulation versatility, TRB is actively developing micro-encapsulated water-soluble flax seed oil powder. Through molecular encapsulation, the active lipids are protected in a starch or clean-label gum matrix. This roadmap aims to achieve:
