Q: How does your product perform in high-temperature processing scenarios such as baking, candy boiling and spray drying? Will it cause yellowing, performance degradation or structural damage?
A: Our non-yellowing food-grade silicon dioxide is specially optimized for extreme high-temperature processing scenarios common in the food industry. It has excellent thermal stability, maintaining stable physical and chemical properties even under long-term high-temperature conditions up to 200℃, with no decomposition, no structural damage, and zero yellowing or discoloration. The ultra-low heavy metal (especially iron ion) control standard we adopt can fundamentally block the yellowing reaction between ethyl maltol and iron ions in high-temperature environments, perfectly solving the discoloration problem of baked goods, hard candies, powdered beverages and other products during high-temperature processing and subsequent storage.
Q: What complete set of compliance documents can you provide for export to global markets? Can it meet the customs clearance and market access requirements of different countries and regions?
A: We can provide a full set of authoritative and legally valid compliance documents for each batch of shipments to fully support your global customs clearance and market access. The standard supporting documents include but are not limited to: Certificate of Analysis (COA) with full test items, Food Additive Production License, Health/Phytosanitary Certificate, Commercial Invoice, Packing List, and Bill of Lading. For specific regional markets, we can also provide the full set of certification documents required for local access, including FDA attestation, SHC HALAL certificate, OU KOSHER certificate, ISO system certification, FAMI-QS certificate and SEDEX audit report, covering the access requirements of Southeast Asia, the European Union, North America, the Middle East, Oceania and other mainstream global markets.
Q: Can your food-grade silicon dioxide be compounded with other food additives such as sweeteners, flavors, spices and milk powder? Are there any compatibility precautions?
A: Our food-grade silicon dioxide has excellent chemical inertness and material compatibility, and can be safely compounded with almost all common food raw materials and food additives, including but not limited to white granulated sugar, glucose, maltodextrin, ethyl maltol, various sweeteners, edible flavors, milk powder, starch, seasonings and other raw materials. It will not react with the above materials, nor will it affect the functional properties of other additives. The only recommended precaution is to pre-mix it with powdered raw materials evenly in a dry environment before adding liquid ingredients, to avoid agglomeration caused by premature moisture absorption, and our technical team can provide targeted compounding process guidance according to your specific formula system.
Q: What is your internal control standard for ultra-low heavy metals? How is it superior to the national standard GB 25576-2010 and FDA 21 CFR regulations?
A: We have established a far stricter internal control system for heavy metal residues than international and national mandatory standards, targeting the core demand of non-yellowing in food processing. For iron ions, which are the core cause of food yellowing, our internal control limit is ≤5ppm, which is far lower than the 30ppm limit of the national standard GB 25576-2010 and the FDA regulatory limit. For lead, arsenic and other heavy metals that are critical to food safety, our internal control standards are also 50%-70% lower than the mandatory limits of national and FDA regulations. All control indicators are strictly implemented in 26 full-process inspection procedures from raw material incoming to finished product delivery, and each batch of products must pass the full inspection of precision testing equipment such as atomic fluorescence spectrometers before leaving the factory, ensuring that the heavy metal residues of each batch are stably controlled within the ultra-low internal control range.
Q: If we encounter problems such as uneven dispersion, poor anti-caking effect or unexpected discoloration during production and use, what after-sales technical support can you provide? What is the response time?
A: We have a dedicated technical service team with more than 20 years of industry application experience, providing full-process closed-loop technical support for all cooperative customers. For any problems encountered during production and use, we promise to give a preliminary solution and response within 2 hours after receiving your feedback (working days). For conventional application problems, we can provide remote formula adjustment, process optimization guidance and on-site operation training; for complex and special problems, we can arrange professional technical engineers to conduct on-site debugging and solution formulation according to your needs. At the same time, we can conduct targeted simulation tests in our laboratory to help you locate the root cause of the problem and optimize the formula and production process until the problem is completely solved.
Q: What raw materials are used to produce your food-grade silicon dioxide? Is there a complete traceability system for the whole production chain?
A: Our food-grade silicon dioxide is produced from high-purity sodium silicate raw materials that meet food-grade standards, with no use of recycled raw materials, industrial-grade raw materials or animal-derived ingredients throughout the process, fully complying with the requirements of HALAL and KOSHER dietary regulations. We have established a complete full-chain traceability system, covering raw material supplier qualification review, raw material incoming batch inspection, production process parameter recording, finished product batch testing, and shipment sales tracking. Each batch of products has a unique batch number, which can be traced back to all links of production, testing and raw material supply, fully meeting the global food safety traceability management requirements for food additives.
Q: Can your food-grade silicon dioxide be used in pet food, dietary supplements and other special food scenarios? Does it meet the corresponding regulatory requirements?
A: Yes, our food-grade silicon dioxide is fully suitable for pet food, pet nutritional supplements, human dietary supplements, health food and other special application scenarios. In terms of compliance, our product has passed the FAMI-QS European feed additive quality and safety system certification, fully meeting the production and use standards of pet food and feed additives in the European Union and global mainstream markets; at the same time, it fully complies with the relevant regulations of the US FDA and China's national standards for dietary supplements and health food. We can also provide targeted product parameter customization and application guidance according to the formula characteristics of pet food and dietary supplements.
Q: Do you provide environmentally friendly packaging solutions? Can it meet the plastic recycling and environmental protection regulations of the European Union and other regions?
A: We attach great importance to the global environmental protection and sustainable development requirements, and can provide a variety of environmentally friendly packaging solutions that meet international regulations while ensuring the moisture-proof and waterproof performance of the product. In addition to conventional composite packaging, we can provide recyclable PE packaging bags, fully degradable environmentally friendly inner bags, and packaging solutions that meet the EU's Single-Use Plastics Directive and plastic recycling labeling requirements. All packaging materials are food-grade, non-toxic and odorless, and will not cause contamination to the product. We can also customize exclusive environmentally friendly packaging solutions according to your brand's sustainable development needs and regional environmental protection regulations.
Q: How do you control the risk of cross-contamination in the production process? Does your production workshop meet the GMP requirements for food production?
A: Our production base is built in strict accordance with the GMP food-grade production management specifications, with a fully enclosed and dust-free production workshop, independent production lines for food-grade products, and a strict zoning management system for raw material areas, production areas, finished product areas and testing areas, which fundamentally avoids cross-contamination between different products and different grades of products. We have established a complete production sanitation management system, including personnel entry and exit disinfection procedures, equipment cleaning and disinfection protocols, and regular environmental microbial testing.
