Our TSG strictly complies with ISO 9001, ISO 22000, FSSC 22000, HACCP, and follows FDA GRAS and EU  regulations for food-grade steviol glycosides.

We use HPLC analysis for every batch, maintaining ≥95% total steviol glycosides content with ≤4% moisture, ≤1% ash, and ≤10ppm heavy metals through controlled crystallization processes.

All batches undergo heat sterilization with strict monitoring: aerobic plate count <1000 CFU/g, yeasts & molds <100 CFU/g

We implement food-grade ethanol purification with GC monitoring to guarantee <50ppm ethanol residue, meeting ICH Q3C guidelines for Class 3 solvents.

Each batch includes a Certificate of Analysis with HPLC assay, heavy metals, microbial test results, solvent residue analysis, and full traceability from raw leaves to final product.

TSG is vacuum-packed in food-grade PE bags with desiccant, stored at <25°C/<65% RH, maintaining quality for 36 months with periodic stability testing (color, moisture, purity).

We implement strict GAP standards for stevia leaves cultivation with pesticide/pollutant screening (≤0.01ppm for 208 pesticides) and glycoside content verification before processing.

Our triple-coating technology (food-grade dextrin+SiO₂+cellulose) reduces moisture absorption to <2% at 75% RH/25°C for 24h - 5× better than standard TSG products.

Our facilities hold NSF-cGMP certification with Class 100,000 clean rooms, automated process controls, and segregated production lines to prevent cross-contamination.

We maintain an allergen-free facility (no gluten, dairy, nuts etc.) with validated cleaning procedures and ATP swab testing to ensure <10μg/cm² protein residue between batches.

We use blockchain-enabled QR coding with complete genealogy tracking - from leaf cultivation lot numbers to extraction parameters, purification data, and final packaging records.

We conduct accelerated stability testing (40°C/75%RH for 6 months) and real-time studies per ICH Q1A guidelines, with monitoring of assay (>95%), moisture (<4%), and microbial growth at 0/3/6/12/24/36 month intervals.

Our micronization process ensures 95% particles are 80-120 mesh (125-180μm) with laser diffraction monitoring, achieving optimal solubility (>99.5% in water at 25°C) for consistent performance.

We use proprietary membrane filtration (0.2μm ceramic filters) followed by chromatography purification, achieving 92-95% recovery rates while eliminating 99.9% of impurities - far superior to conventional ethanol extraction.

Through our patented decolorization process, we guarantee ≤0.5% transmittance at 420nm with spectrophotometric monitoring every 30 minutes during production.

Our smart factory uses Siemens PLCs with PAT (Process Analytical Technology) for real-time HPLC monitoring and AI-driven parameter adjustments every 5 seconds, ensuring ±0.3% purity deviation.
