High-purity botanical products processed under stringent international standardization frameworks.
Konjac Extract, derived from the tuber of the perennial plant Amorphophallus konjac, has transitioned from a traditional Asian culinary ingredient to one of the most sought-after polysaccharides in modern industry. At the chemical level, its active component, Konjac Glucomannan (KGM), is a soluble, dietary fiber consisting of D-mannose and D-glucose residues connected by β-1,4 linkages. This unique molecular architecture grants it unmatched physical properties, notably its extreme water absorption capacities and the ability to form highly viscous pseudoplastic solutions.
As global consumer preferences shift toward natural, clean-label, and plant-based alternatives, Konjac Extract has emerged as an indispensable hydrocolloid. Its exceptional gelling capabilities, combined with thermal reversibility or irreversibility under specific pH controls, make it a core ingredient across food processing, nutraceutical formulations, cosmetic gels, and drug delivery platforms.
For procurement professionals, understanding the science of KGM viscosity, acetyl group structure, and molecular weight distribution is vital. Controlling these attributes during industrial refining ensures stable formulation outcomes, which is why working directly with an experienced producer like TRB is essential.
A pioneer in botanical extraction, combining industrial scale with scientific precision for over two decades.
Founded on principles of innovation and rigorous quality control, Nanjing Tong Rui Bio-Tech Co., Ltd. (TRB) has established itself as a leading global manufacturer and exporter of botanical extracts and active phytocompounds for more than 20 years. We offer a comprehensive commercial portfolio that bridges the gap between raw botanical resources and modern manufacturing requirements, supplying sectors such as pharmaceuticals, functional food, sports nutrition, and personal care.
TRB operates as a high-technology enterprise that integrates agricultural sourcing, scientific research and development (R&D), GMP-compliant extraction, and dedicated international sales channels. Beyond our signature Konjac Extract products, TRB's capabilities extend to Herbal Extracts, Natural Sweeteners, Nootropics, Fruit & Vegetable Juice Powders, Pure Essential Oils, and Standardized Bee Products.
Our commitment to technical excellence and client service has earned us global recognition. We are proud to announce that TRB has been honored with the 2026 "Global Biotechnology and Life Sciences Award" as the ''Best Global Herbal Extract Provider 2026'', reinforcing our standing as a trusted partner in the international health ingredient supply chain.
Over two decades of optimizing extraction processes, maximizing active yield efficiency, and isolating challenging complex polysaccharides like Glucomannan.
Formulation of custom particle sizes, granular solutions, and specialized blends targeting brain health (Nootropics), metabolic optimization, and weight management.
Our operations are backed by global food safety, quality, and dietary certifications, ensuring quick custom clearance and strict downstream compliance.
TRB's industrial footprint comprises three specialized factories designed to mitigate contamination risks and optimize operational throughput: one dedicated to herbal extraction, another to standardized bee products, and a third focused on specialized animal-derived biological products.
All production lines adhere strictly to international manufacturing regulations. Our facilities maintain active compliance credentials including GMP, ISO, HACCP, ORGANIC, FDA registration, HALAL, and KOSHER Certificates. These standards enable us to deliver traceable, audit-ready products for demanding pharmaceutical and food manufacturers globally.
Our mills feature low-temperature dry air systems that prevent polysaccharide degradation, producing premium Konjac powders with viscosity profiles ranging from 20,000 mPa.s to over 40,000 mPa.s.

How TRB utilizes digital manufacturing to ensure consistent pricing, safety, and supply continuity.
Our extraction lines feature closed-loop, automated controls that protect the raw material from atmospheric humidity, preventing starch gelatinization and maintaining consistent mesh size and bulk density.
By using multi-stage alcohol precipitation, we eliminate starch, soluble sugars, and sulfur dioxide residues, resulting in high-purity Glucomannan that meets global clean-label standards.
We work directly with major agricultural co-ops in optimized Chinese cultivation zones. This vertical connection protects our clients from market price swings and guarantees reliable supply year-round.
From standard meat alternatives to pharmaceutical excipients, how our customers deploy KGM globally.
In Europe and North America, plant-based food manufacturers use Konjac Glucomannan to replicate the texture of animal fat in vegan burgers and sausages. Its heat-stable gel properties keep these products juicy and structural during cooking.
With consumers rejecting synthetic modified starches and gums, KGM provides a natural, gluten-free, and calorie-free thickener. It remains stable in acidic environments, making it ideal for salad dressings and sauces.
Thanks to its ability to swell in water, Konjac Extract is widely used in weight management supplements. Its prebiotic properties also support metabolic health by promoting beneficial gut bacteria.
Our pharmaceutical-grade Konjac powders serve as natural binders and disintegrants. In excipient design, KGM is utilized in controlled-release tablets, protecting therapeutic molecules through the stomach for target release in the colon.
TRB is dedicated to expanding the potential of plant-based materials. In recent years, our R&D team has focused on utilizing nootropics and cellular health properties of botanical extracts, creating options designed to support brain health, active aging, and longevity.
Our global shipping network distributes standardized products to over 60 countries. We prioritize batch consistency, absolute purity, and reliable delivery, helping brand owners bring high-quality formulations to market with confidence.
