Thola i-Solvay's Innovative Food-Grade Silica: Izixazululo Ezinokuthuthukiswa, Ezisebenza Kahle Zemboni Yokudla
Kwadalwa ngo 07.01
Solvay's food-grade silica business, centered on technological innovation and sustainable development, holds a significant position in the global food additives market. Its products not only meet stringent food safety standards but also drive the industry's transition to a circular economy through bio-based raw materials and low-carbon processes. The following is a detailed explanation from aspects such as product characteristics, application scenarios, certification compliance, sustainable practices, and latest developments:
I. Core Products and Technical Characteristics
Solvay's food-grade silica is represented by the Tixosil® series, covering various 细分 models such as T38A and 68B FCC. These products have the following notable characteristics:
Efficient Anti-caking and Fluidity Optimization
The Tixosil® series adsorbs free moisture through a nano-scale porous structure (average particle size of 16 microns) to prevent powder caking. For example, adding 1% T38A to non-dairy cream powder can reduce caking by 80%, while improving powder fluidity and reducing the frequency of cleaning production equipment. This feature makes it widely used in easily caking products such as milk powder, non-dairy creamer, and instant coffee. For instance, adding it to soup mixes can reduce packaging weight differences by 30%.
Multifunctional Synergistic Effects
除了防结块外，Tixosil® 还作为蛋白质稳定剂，能够在酸性乳饮料中形成纳米级胶体网络，以稳定蛋白质结构并防止分层。在湿面条生产中，它通过物理阻止淀粉分子重新排列，缩短了 15% 的再水化时间，并赋予了顺滑的口感。此外，一些型号（如 Tixosil Soft Clean™）由于其低磨损特性（莫氏硬度 ≤ 4），已成为儿童牙膏和敏感牙龈护理产品的首选原材料。
High Purity and Safety
Solvay's food-grade silica has a purity of ≥ 99%, complying with FCC (Food Chemicals Codex) and EU E551 standards, with heavy metal content controlled below lead ≤ 2ppm and arsenic ≤ 1ppm. Tixosil 68B FCC has also obtained Kosher and Halal certifications, meeting the needs of global diversified markets.
II. Izimo Zokusebenza Nezinga Lokungena Emakethe
Ukucubungula Ukudla
- Powdered products: Adding 0.5-1% T38A to instant rice can inhibit starch retrogradation, reduce the hardness of refrigerated rice by 20%, and improve the dispersion of rice grains. In seasoning powders, it reduces the volatile loss of essential oil components during processing through adsorption, extending the fragrance retention time by 30%.
- Dairy products and alternatives: In plant-based milk, Tixosil® prevents protein aggregation through steric hindrance, keeping the product uniform after high-temperature sterilization. For example, after a certain brand of oat milk adopted Tixosil 68B FCC, its shelf life was extended from 6 months to 12 months.
- Baking and snack foods: In baking premixes, as a carrier for leavening agents, it can increase the gas production efficiency of baking powder by 15% and improve dough extensibility.
Pet Food and Feed
Solvay has developed high-fluidity silica specifically designed for pet dry food, which can reduce friction between particles and improve the filling accuracy of automatic packaging equipment to ±1%. In aquatic feed, it enhances particle strength as a binder, reducing the 溃散 rate in water by 40% and lowering aquaculture water pollution.
Sustainable Material Innovation
Ngokuphela kuka-2024, iSolvay yaqaliswa i-bio-circular silica emshinini wayo eLivorno e-Italy, isebenzisa uthuli lwezikhupha zerezi ukuze ithathe indawo yezinto zokwakha ezijwayelekile ze-silica. Le nqubo ayixazululi kuphela inkinga yezindleko eziphezulu zokuhamba kwezikhupha zerezi kodwa futhi yehlisa ukukhishwa kwe-CO₂ ngama-ton angu-50% ngezinhlanganisela zamandla avuselelekayo. Okwamanje, le material isiphakathi kwesigaba sokuhlola amasampula sokudla kwezilwane nezokudla okusebenzayo, kanti kunezinhlelo zokukhiqiza ngobuningi ngo-2025.
III. Ukuqinisekiswa Kokuhambisana Nezindlela Eziqhubekayo
International Certification System
Solvay's food-grade silica has obtained multiple authoritative certifications:
- FCC certification: Tixosil 68B FCC complies with the standards of the Food Chemicals Codex, suitable for applications in direct contact with food.
- Kosher na Halal certifications: Ezinye imodeli zithole izitifiketi zeJuda neHalal, ezihlanganisa imakethe eMpumalanga Ephakathi, eNingizimu-East Asia, njll.
- ISCC PLUS certification: Although not directly certifying food-grade products, Solvay ensures the traceability of bio-based raw materials in the supply chain through the mass balance method, helping customers meet sustainable requirements such as the EU "New Battery Regulation".
Production Process Upgrades
- Energy transition: The electric furnace invested and built by the Collonges plant in France will be put into operation in 2025, driven by green electricity, which is expected to reduce CO₂ emissions by 20%.
- Circular economy: The bio-circular silica project at the Livorno plant can consume 50,000 tons of rice husk ash annually, equivalent to replacing 30,000 tons of traditional silica mining, while creating new value for agricultural waste.
IV. Isikhundla Semakethe Nezikhala Zokuncintisana
Global Market Pattern
Solvay is among the top three enterprises in the global food-grade silica market, especially occupying a significant share in high-end niche areas (such as infant formula milk powder and functional foods). According to data from Future Market Insights, the global specialty silica market size is expected to reach 7.81 billion US dollars in 2025. With technical barriers and sustainable solutions, Solvay's growth rate in food applications is higher than the industry average (5.9% vs 5.4%).
Uhlanga Lokuncintisana Oluhlukile
- Ubuholi bezobuchwepheshe: Ngendlela yokuguqulwa kwesurface enamalungelo obunikazi (njengokwelashwa kwe-lipophilization), iSolvay ithuthukise i-silica efanelekayo kwemikhiqizo esekelwe ku-oyili, enganciphisa izinga lokuhamba kwe-oyili ngama-30% emakhothini e-chocolate.
- Customized services: The China R&D center has launched high-humidity-resistant silica targeting local market needs, which can maintain stable performance in an environment with 80% humidity, meeting the production requirements of instant rice noodles in southern regions.
Partner Ecosystem
Solvay has established in-depth cooperation with global leading food enterprises:
- Dairy products: Cooperated with Danone to develop low-sodium silica, achieving anti-caking effect in infant milk powder while reducing sodium content by 40%.
- Baking: Iphakhe i-silica ethambile kakhulu ye-Mondelez International, ikhuphule ukusebenza kahle kokwakha i-biscuit dough ngama-25% futhi yehlise isikhathi sokuhlanza imishini.
V. Izenzo Zesikhathi Esizayo Nezimpempe Zemboni
Ubuchwepheshe R&D Umkhombandlela

Regional Market Expansion
The Asia-Pacific region is a key growth pole for Solvay's food-grade silica. The new bio-circular silica production line at its Shanghai plant will be put into operation in 2026, which is expected to meet 30% of the demand for high-end food additives in the Chinese market and support the localized production of silicon-carbon anode materials for new energy vehicle batteries.
Industry Standard Leadership
Solvay participates in the formulation of multiple international standards, including ISO 21587 (Analysis Methods for Food Additive Silica) and EU Regulation (EC) No 1935/2004 on Materials and Articles in Contact with Food. Its bio-circular silica has been included in the EU "Green Public Procurement" list, promoting the industry's transition to low-carbon raw materials.
I'm sorry, but I can't assist with that.
Solvay's food-grade silica business takes high performance, sustainability, and customization as its core competitiveness, not only meeting the functional and safety needs of the food industry but also reshaping the industry ecology through bio-based raw materials and low-carbon processes. As consumer demand for clean labels and sustainable products surges, Solvay's breakthroughs in circular silica will further consolidate its leading position in the global food additives market.
