Direct supply from Xi'an manufacturing facilities with zero secondary repacking exposure. Every botanical batch is quantified for active marker content and strictly calibrated against tropical transport degradation.
From the industrial corridors of SIER (Surabaya Industrial Estate Rungkut) to processing plants in Gresik and Sidoarjo, natural antioxidants resolve unique environmental and chemical hurdles.
Surabaya operates within a year-round humid tropical climate with average relative ambient humidity exceeding 75% to 85%. For food processors across East Java blending palm fractions, coconut derivatives, and ready-to-eat seasoning sauces, auto-oxidation and hydroperoxide formation present major shelf-life bottlenecks.
By substituting vulnerable synthetic preservatives (such as BHT and BHA) with oil-soluble Astaxanthin oleoresin and water-soluble Instant Black Tea theaflavins, Surabaya manufacturers protect lipid structures against secondary aldehyde rancidity while meeting modern export clean-label mandates.
Our micro-milled polyphenols act as primary chain-breaking electron donors, effectively quenching free peroxide radicals without impacting final sensory aromas or altering the crispness of finished snack foods.
Surabaya’s vibrant beauty, personal care, and topical wellness brands demand natural actives that resist intense UV exposure and rapid temperature cycling in regional distribution routes. Conventional botanical preparations often suffer enzymatic browning and active degradation within weeks of shelf storage.
Xi'an Sirn Bio-Tech integrates specialized vacuum spray drying and microencapsulation technologies to deliver botanical powders such as Rosa Roxburghii and Aronia Concentrate with preserved natural organic acids, maintaining active color retention and radical absorption capacity throughout the product lifespan.
These bioactives integrate cleanly into dermo-cosmetic toners, anti-pollution sunscreens, and brightening face creams without causing phase separation or gritty tactile anomalies.
A closer look at how regulatory requirements, export standards, and supply chain logistics are shifting antioxidant purchasing across Surabaya and East Java.
Mass-market food, ready-to-drink (RTD) beverage, and culinary sauce producers across Rungkut and Pasuruan are phasing out artificial preservatives. Natural plant flavonoids and polyphenol extracts now serve dual functions: acting as declared antioxidants while preserving original food hue without artificial colorants.
Navigating oceanic freight through Tanjung Perak Harbor requires stable packaging. Local procurement managers favor ingredients packed in multi-layered, vacuum-sealed aluminium pouches and robust fibre drums with food-grade desiccant liners to prevent hygroscopic clumping during customs staging.
Formulators catering to domestic and broader ASEAN retail channels demand raw extracts free of forbidden processing aids, synthetic carriers, or unlisted solvent traces. Source factories must deliver full chromatographic verification and transparent process flowcharts to clear BPOM registration requirements.
Combining the botanical wealth of the Qinling Mountains with advanced academic extraction engineering, our facilities support your product pipeline from pilot testing to multi-ton container shipments.
Xi'an Sirn Bio-Tech Co., Ltd. operates two primary industrial plants running 4 standardized high-capacity production lines and 2 dedicated pilot lines, fully built to meet GMP operational criteria. Our technical team includes 18 experienced technicians and 5 licensed TCM pharmacists working across extraction, drying, and batch purification.
Rather than relying solely on third-party test houses, our in-house QC laboratory houses gas chromatographs (GC), high-performance liquid chromatographs (HPLC), UV spectrophotometers, and ultrasonic extraction test setups. We quantify and certify active markers—such as icariin, anthocyanins, polyphenols, and pure astaxanthin—for every single manufacturing lot.
Furthermore, our joint research laboratories with Xi'an Jiaotong University, Northwest University, and Xi'an University of Science and Technology allow us to develop custom botanical isolation methods, stabilize sensitive active fractions, and support complex OEM/ODM projects.
Direct technical and logistical clarity for procurement directors, QC heads, and formulation scientists importing botanical raw materials to East Java.
