Leveraging over two decades of extraction expertise to deliver highly pure, standardized natural compounds for wellness formulations worldwide.
Black Garlic (fermented *Allium sativum*) has transcended its traditional culinary origins to become one of the most prominent ingredients in modern preventative wellness. The key driver of its therapeutic superiority is the water-soluble organosulfur compound, S-Allyl-Cysteine (SAC). Unlike raw garlic, which contains highly unstable, oil-soluble organosulfur compounds like allicin, the multi-stage fermentation process converts these harsh precursors into stable, highly bioavailable compounds.
"S-Allyl-Cysteine (SAC) acts as a powerful antioxidant that easily crosses cell membranes, neutralizing free radicals and exhibiting a bioavailability close to 98% in human clinical trials. This makes it an ideal core ingredient for anti-aging and cardiovascular formulations."
During the controlled thermal degradation process of raw garlic bulbs (under elevated temperatures of 60–80°C and relative humidity levels of 70–90%), gamma-glutamyl-S-allyl-L-cysteine is hydrolyzed by the enzyme gamma-glutamyl transpeptidase into S-Allyl-Cysteine. This chemical shift minimizes the pungent mercaptan compounds that cause malodorous breath and gastric distress, producing an ingredient that is sweet, odor-free, and highly concentrated with stable polyphenols and melanoidins.
Our extraction lines utilize non-thermal, eco-friendly solvent separation to yield standardized concentrations of SAC. The table below details the technical specifications of our premium grades:
| Parameters | Standard Specification (Grade A) | Premium Specification (Grade AAA) | Methodology / Standard |
|---|---|---|---|
| Appearance | Light Brown to Dark Brown Powder | Dark Brown Fine Powder | Visual Inspection |
| Active Compound: SAC | ≥ 1.0% | ≥ 3.0% | HPLC-DAD Analysis |
| Solubility | 100% Water Soluble | 100% Water Soluble | Gravimetric Analysis |
| Loss on Drying | ≤ 5.0% | ≤ 4.0% | 105°C / 3 Hours |
| Heavy Metals (Pb, As, Hg, Cd) | ≤ 10.0 ppm | ≤ 5.0 ppm | ICP-MS Method |
| Pesticide Residues | Compliant with USP <561> | Non-detectable | GC-MS / LC-MS |
The global pharmaceutical and nutraceutical sectors are moving rapidly toward natural longevity compounds. Standardized Black Garlic Extract SAC is utilized in four primary macro-industry formulations:
Nanjing Tong Rui Bio-Tech Co., Ltd. (TRB) has spent more than 20 years perfecting active plant ingredient separation. We employ advanced chromatography to isolate and stabilize SAC in industrial volumes.
Annual raw material processing exceeds 12,000 metric tons. Specialized sterile clean rooms (Class 100,000) are reserved for drying and packaging high-potency powders like SAC.
Addressing technical, formulation, and commercial challenges for brands scaling up black garlic extract formulations in international markets.
We offer customized mesh distributions ranging from 80 mesh (standard capsules/tablets) up to 200 mesh superfine powder, which is ideal for smooth incorporation into nutritional sachets, powder mixes, and protein blends.
Using state-of-the-art membrane filtration, we eliminate insoluble cellulose residues. This process creates a 100% cold-water-soluble extract powder that forms a clear liquid, perfect for carbonated or still functional beverages.
Even though fermentation reduces garlic odor, some scent remains. We provide specialized natural masking technologies and micro-encapsulated SAC powders to ensure flavor profiles remain clean and appealing.
Nanjing Tong Rui Bio-Tech Co., Ltd. (TRB), is the China Leading manufacturer and exporter of herbal extracts and its derivatives for more than 20 years.

TRB currently has three factories: one is a herbal extract factory, the second is a bee product factory, and the third is for animal extract products. Our factories carry comprehensive compliance documentation including GMP, ISO, HACCP, ORGANIC, FDA, HALAL, KOSHER Certificates.
In recent years, TRB has focused on the research and development of Nootropics products, such as Brain Health Herb Extract, Anti-Aging Herb Extract, and Longevity Herb Extract, which have received excellent feedback from our customers worldwide. TRB products have been exported to more than 60 countries and regions and have gained an outstanding reputation.
Providing localized quality assurance and fast shipping channels across North America, Europe, and Asia-Pacific.
We assist European brands with documentation for the European Food Safety Authority (EFSA), detailing safe intake concentrations and sourcing traceabilities. Our batch HPLC chromatograms verify that SAC thresholds meet EU Novel Food directives.
For US customers, we provide comprehensive NDI (New Dietary Ingredient) validation data, analytical heavy metal assays (USP <2232> limits), and residual solvent profiles to streamline your FDA GRAS self-affirmation processes.
TRB operates with experienced freight partners to maintain regular shipping routes to European ports (Rotterdam, Hamburg) and North American hubs (LA, NY). We offer DDP (Delivered Duty Paid) shipping to minimize import complications.
At TRB, we continuously innovate our manufacturing technologies to offer our clients superior product performance. Our research roadmap is focused on the following areas:
Encapsulating SAC in phospholipid bilayers to shield active ingredients from stomach acids and enhance cellular absorption rates.
