Evonik Degussa 食品级硅石抗结剂：性能与挑战

Evonik Degussa的食品级硅石抗结剂，围绕Sipernat®和AEROSIL®产品线，在全球食品添加剂市场中占据重要地位，得益于先进的制造工艺和严格的质量控制。以下是从产品特性、市场定位、优势和局限性等方面的详细分析：

``` I. 核心产品信息和技术参数 ```

1. Product Lines and Process Characteristics

• Sipernat® 系列（沉淀二氧化硅）

Represented by Sipernat® 22S and 50S, they are produced through a precipitation process, featuring high oil absorption (e.g., Sipernat® 22S has a DBP oil absorption value of 265%) and uniform particle size distribution (average particle size 7-11.5 μm). Their porous structure can adsorb oils and moisture in food, forming a physical barrier to prevent caking, making them suitable for high-fat content foods (such as milk powder, baking fats) and powdered seasonings.

◦ 技术参数:

▪ SiO₂ content: ≥98% (Sipernat® 22S)

msgstr "特定表面积：190 m²/g (Sipernat® 22S)"
```

▪ Perda por secagem: ≤6% (a 105°C por 2 horas)

• AEROSIL® 系列（气相二氧化硅）

Representado por AEROSIL® 200F, se preparan utilizando un proceso de hidrolysis por llama, con partículas a nanoescala (tamaño promedio de partícula de 12 nm) y una superficie específica ultra alta (175-225 m²/g). Su estructura de red tridimensional puede mejorar eficazmente la fluidez de los polvos, adecuada para productos lácteos de alta gama, suplementos nutricionales y otros escenarios con estrictos requisitos de dispersabilidad.

msgstr "SiO₂ 內容：>99.8%"
```

msgid "Bulk density: approximately 50 g/L"
msgstr "密度：约 50 g/L"

▪ Compliance certifications: in line with EC No. 852/2004, FDA 21 CFR 172.480 and FAMI-QS standards

msgid "2. Analysis of Core Functions" msgstr "2. 核心功能分析"

• Anti-caking Mechanism: Through physical adsorption (oil absorption value 265-300 g/100g) and spatial barrier effect, it prevents particles from aggregating due to humidity or static electricity.

• Fluidity Optimization: La nanostructura de AEROSIL® 200F puede reducir significativamente el coeficiente de fricción de los polvos, manteniendo productos como la leche en polvo sueltos en un ambiente de 40°C/75% HR.

• Carrier Function: Sipernat® 50S puede adsorber sabores líquidos o vitaminas, convirtiéndolos en polvos sólidos de flujo libre, extendiendo así la vida útil de los ingredientes sensibles.

II. 全球市场定位与竞争格局

``` 1. Part de marché et classement de l'industrie ```

• Global Competitiveness: Evonik is one of the major suppliers of fumed silica (accounting for about 35% of the high-end food-grade anti-caking agent market) and precipitated silica globally, jointly dominating the market with Cabot and Wacker.

• Regional Layout: In the Asia-Pacific region, Evonik's food-grade silica has a market share of about 18%, especially in the high-end dairy products and health products fields.

msgid "2. Competitive Advantage Areas" msgstr "2. 竞争优势领域"

• 技术障碍：气相AEROSIL®系列在纳米级分散性和热稳定性（耐受超过200°C的温度）方面优于PQ和Grace等竞争对手。

• Compliance Coverage: The products have passed multiple international certifications such as FDA, EFSA, and Kosher, supporting export-oriented food processing enterprises to meet global regulatory requirements.

III. 差异化优势与技术亮点

msgid "Leading Performance" msgstr "领先表现"

• Anti-caking Efficiency: The oil absorption value of AEROSIL® 200F (280-300 g/100g) is higher than that of Grace SYLOID 63 FP (200 g/100g), performing better in high-humidity environments.

• 处理兼容性：Sipernat®系列的高体积密度（例如，Sipernat® 22S为6.2 lb/ft³）减少了静电吸附，促进了与其他辅料的混合。

msgid "2. Sustainability and Process Innovation" msgstr "2. 可持续性与流程创新"

• Green Production: Evonik promotes the resource utilization of wastewater from the precipitation process, reducing water consumption per ton of products by 40%, which is in line with China's "Dual Carbon" policy orientation.

• Customized Services: Hydrophobic modified grades (such as AEROSIL® R972) and high specific surface area models (such as AEROSIL® 300) are provided to meet special application needs.

IV. 限制与应用挑战

msgid "Cost and Economy" msgstr "成本与经济"

• 高成本的烟熏法：AEROSIL®系列的价格比沉淀产品高30-50%，限制了其在低端食品（如普通食盐）中的应用。

• 敏感性对添加量：过量使用可能导致粉末过度分散，影响食品口感（例如，冲泡奶粉时的颗粒感）。

msgid "2. Regulations and Compatibility" msgstr "2. 规章与兼容性"

• 限制区域：在欧盟，食盐中二氧化硅（E 551）的最大使用量为5 g/kg，部分Evonik型号因颗粒大小问题需要额外许可。

• Compatibilité des risques : Un contact prolongé avec des composants fortement acides ou alcalins peut réduire les performances d'adsorption, il est donc nécessaire de réaliser d'abord des tests de compatibilité.

msgid "3. Dust Control" msgstr "3. 控尘"

• Production Challenges: The low density (50 g/L) of the AEROSIL® series is prone to dust generation, requiring professional dust removal equipment in clean workshops.

V. 典型应用场景及效果

Field	Product Model	Core Function	Effect Data
Dairy Products	AEROSIL® 200F	Prevent milk powder from caking due to moisture absorption and improve fluidity.	In a 40°C/75% RH environment, adding 1-2% can reduce the caking rate of milk powder by 80%.
Seasonings	Sipernat® 22S	Adsorb liquid flavors, convert them into solid powders, and improve dispersibility.	Adding 2-5% to chicken essence reduces the caking rate from 35% to <5% and shortens the dispersion time to within 15 seconds.
Baked Foods	Sipernat® 50S	Prevent flour from caking due to humidity changes and optimize dough processing performance.	The ductility of the dough is improved by 12%, and the texture of the finished product is refined.
Nutritional Supplements	AEROSIL® 200F	Protect probiotics and vitamins from oxidative degradation and extend shelf life.	In the 40°C accelerated test, the retention rate of active ingredients increased from 60% to 92%.
