发现索尔维的创新食品级硅石：可持续的高性能解决方案，服务于食品行业

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:

Solvay的食品级二氧化硅由Tixosil®系列代表，涵盖了各种细分型号，如T38A和68B FCC。这些产品具有以下显著特性：

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%.

In addition to anti-caking, Tixosil® also functions as a protein stabilizer, which can form a nano-scale colloidal network in acidic milk drinks to stabilize the protein structure and prevent stratification. In wet noodle production, it shortens the rehydration time by 15% by physically blocking the rearrangement of starch molecules and imparts a smooth taste. Moreover, some models (such as Tixosil Soft Clean™) have become the preferred raw materials for children's toothpaste and sensitive gum care products due to their low abrasion characteristics (Mohs hardness ≤ 4).

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.

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 dispersion rate in water by 40% and lowering aquaculture water pollution.

At the end of 2024, Solvay launched bio-circular silica at its Livorno plant in Italy, using rice husk ash to replace traditional silica raw materials. This process not only solves the problem of high transportation costs of rice husks but also reduces CO₂ emissions per ton of silica by 50% through the integration of renewable energy. Currently, this material has entered the sample evaluation stage for pet food and functional foods, with plans for large-scale production in 2025.

Solvay的食品级硅石已获得多个权威认证：

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%).

Solvay ha establecido una cooperación profunda con empresas alimentarias líderes a nivel mundial:

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.

Solvay参与了多个国际标准的制定，包括ISO 21587（食品添加剂二氧化硅的分析方法）和欧盟法规（EC）第1935/2004号关于与食品接触的材料和物品。其生物循环二氧化硅已被纳入欧盟“绿色公共采购”名单，促进了行业向低碳原材料的转型。

Solvay的食品级硅石业务以高性能、可持续性和定制化作为其核心竞争力，不仅满足食品行业的功能和安全需求，还通过生物基原材料和低碳工艺重塑行业生态。随着消费者对清洁标签和可持续产品的需求激增，Solvay在循环硅石方面的突破将进一步巩固其在全球食品添加剂市场的领先地位。
