PQ Food-Grade Silica Anticaking Agent is a functional additive specifically designed for the food industry, playing a key role in powdered food processing with its unique physicochemical properties and broad compliance. Below is a comprehensive overview of its core information:

Product Characteristics and Technical Advantages

1.1 Propiedades fisicoquímicas

High Purity: PQ food-grade silica typically contains ≥99% SiO₂, complying with national standards such as GB 25576-2020. It appears as a white, free-flowing powder with uniform particle size distribution (e.g., the Gasil series has an average particle size of ~6.8 μm), effectively preventing particle aggregation.
```po msgid "Mesoporous Structure: The mesoporous design endows it with a high specific surface area (e.g., 185 m²/g as measured by BET method) and an oil absorption value of 280–300 g/100g. It can adsorb excess moisture and oil in foods, forming a barrier to prevent caking." msgstr "介孔结构：介孔设计赋予其高比表面积（例如，通过BET方法测得为185 m²/g）和280–300 g/100g的油吸收值。它可以吸附食品中的多余水分和油脂，形成防止结块的屏障。" ```
Chemical Inertness: Insoluble in water and most acids, reacting only with hydrofluoric acid and strong alkalis, ensuring no interaction with food components and preserving original flavor and nutrition.

1.2 过程适应性

Low Dust Emission: With a high bulk density (e.g., Gasil AB905 has a bulk density of 6.2 lb/ft³), it reduces dust generation during processing, meeting modern clean production requirements.
Thermal Stability: Maintains structural stability at high temperatures, suitable for processing scenarios like baking and frying.

Application Fields and Functional Analysis

2.1 核心应用场景

2.1.1 产品乳制品和营养补充剂

Milk Powder: Adding 1–3% PQ silica significantly improves flowability and prevents caking caused by moisture absorption. For example, in instant milk powder, its porous structure adsorbs moisture, keeping the product loose under 40℃/75% RH conditions.
Nutritional Fortifiers: Como portador de vitaminas, probióticos, etc., protege los componentes sensibles de la oxidación y degradación, extendiendo la vida útil.

2.1.2 调味品和速食食品

``` msgid "Powdered Flavors/Soups: By adsorbing liquid spices, it converts them into free-flowing solid powders for easy measurement and mixing. For instance, adding 2–5% PQ silica to chicken bouillon prevents caking and enhances dispersibility." msgstr "粉末调味料/汤：通过吸附液体香料，它将其转化为易于测量和混合的自由流动固体粉末。例如，向鸡肉高汤中添加2-5%的PQ硅石可以防止结块并增强分散性。" ```
``` msgid "Instant Coffee/Beverages: Improves particle flowability, reduces caking during brewing, and adsorbs excess moisture to maintain product stability." msgstr "速溶咖啡/饮料：改善颗粒流动性，减少冲泡过程中的结块，并吸附多余水分以保持产品稳定性。" ```

2.1.3 烘焙和谷物产品

Flour/Cake Mix: Previene el apelmazamiento debido a cambios de humedad, mejora el rendimiento del procesamiento de la masa y realza la textura de los productos terminados.
Puffed Foods: 作为一种抗结剂和润滑剂，它减少了包装中的粘连并改善了外观质量。

2.2 新兴应用

2.2.1 Alimentos de origen vegetal

In plant proteins (e.g., soybean protein powder), PQ silica adsorbs oil, prevents layering, improves solubility, and enhances product stability.

2.2.2 功能性食品

Used as a carrier for functional ingredients like dietary fiber and probiotics, enhancing their stability during processing and storage.

Compliance and Quality Assurance

3.1 监管认证

Domestic Standards: Complies with GB 25576-2020 National Food Safety Standard for Food Additive Silica, allowing use in dairy products, seasonings, and other food categories with a maximum addition of 15–20 g/kg.
``` msgid "International Certifications: Some grades are certified by FDA (21 CFR 172.480) for export foods, and also comply with EU EFSA (E 551), Kosher, and Halal standards." msgstr "国际认证：某些等级获得FDA（21 CFR 172.480）认证，适用于出口食品，并符合欧盟EFSA（E 551）、犹太洁食和清真标准。" ```
Special Compliance: While PQ products have limited use in table salt under 2025 regulations, they remain compliant in other food sectors.

3.2 生产管理

Certified by ISO 9001 quality management system, with some production lines complying with GMP standards to ensure batch-to-batch consistency.
Export products meet international market access requirements such as Russian EAC certification.

Differentiated Advantages vs. Competitors

4.1 Comparaison des performances

Anticaking Efficiency: PQ silica’s oil absorption (280–300 g/100g) is higher than some competitors (e.g., Grace SYLOID 63 FP’s 200 g/100g), performing better in high-humidity environments.
``` msgid "Processing Compatibility: Its high bulk density (e.g., 6.2 lb/ft³ for Gasil AB905) facilitates mixing with other excipients and reduces electrostatic adsorption." msgstr "处理兼容性：其高散装密度（例如，Gasil AB905 的 6.2 lb/ft³）有助于与其他辅料混合，并减少静电吸附。" ```

4.2 成本效益

High adsorption capacity reduces usage, with lower overall costs than traditional anticaking agents (e.g., sodium aluminosilicate).
Low dust emission minimizes processing loss and improves production efficiency.

Usage Recommendations and Precautions

5.1 控制剂量

Recommended addition: 0.5–3%, adjusted according to food type and environmental humidity. For example, milk powder in high-humidity regions may require 2–3% addition.

5.2 兼容性

Avoid prolonged contact with strongly acidic or alkaline substances to prevent affecting adsorption performance.
Can be used in combination with excipients like magnesium stearate and microcrystalline cellulose, but compatibility testing is required first.

5.3 条件存储

Store in a sealed container in a dry, cool place to avoid moisture affecting flowability.

Sustainability and Industry Trends

6.1 Producción Verde

PQ Group promotes process optimization to reduce energy consumption and waste emissions, aligning with China’s "Double Carbon" policy.

6.2 监管适应

In response to 2025 food additive regulations, PQ is adjusting product formulations to ensure compliance in core sectors like dairy and seasonings.

Conclusion

PQ food-grade silica anticaking agent stands out as the preferred additive for milk powder, seasonings, baked foods, and other fields, leveraging three core advantages: high-efficiency anticaking, broad compliance, and process adaptability. Its mesoporous design and high adsorption capacity not only solve caking issues but also support the development of functional foods.
