Evonik SIPERNAT 22S: Food-Grade Silica Dioxide, Empowering Anti-Caking and Thickening Solutions for the Processing Sector

Evonik SIPERNAT 22S has become a preferred raw material for many food manufacturers to optimize production and enhance quality, thanks to its stable performance and wide adaptability.


In the food processing industry, the selection of anti-caking agents and thickeners directly impacts product quality and consumer experience. As a representative product of food-grade precipitated silica dioxide (commonly known as silica white), Evonik SIPERNAT 22S has become a preferred raw material for many food manufacturers to optimize production and enhance quality, thanks to its stable performance and wide adaptability. This article will analyze how this raw material addresses processing pain points and supports food quality upgrading from three perspectives: product characteristics, core applications, and procurement logic, providing insights for industry practitioners.

1. Product Positioning: A Performance Benchmark for Food-Grade Silica Dioxide

Evonik SIPERNAT 22S is specifically developed for the food industry. Its core value lies in integrating the dual functions of "anti-caking" and "thickening" — it solves powder caking issues through precise physical properties while optimizing the texture of liquid foods. Throughout the process, it complies with food-grade safety standards, making it a typical raw material that balances "safety" and "functionality".

2. Core Characteristics: Four Advantages Supporting Processing Needs

  1. High Purity for Safety Assurance: The raw material strictly meets food-grade specifications with no impurity residues, eliminating food safety risks at the source. It is suitable for food scenarios that are directly consumed, such as baking, seasoning, and beverages.
  2. Uniform Particle Size for Improved Texture: The uniform particle distribution prevents caking and stratification of powders caused by uneven particle sizes. It also forms a stable dispersion system in liquids without affecting the food’s original taste (e.g., avoiding a rough granular texture).
  3. Efficient Anti-Caking for Enhanced Fluidity: For caking-prone powders like salt, sugar, and flour, it reduces adhesion between particles through physical barrier effects, maintaining a loose powder state. This facilitates metering, mixing, and packaging during production.
  4. Mild Thickening for Better Texture: In liquid foods such as fruit juices, dairy drinks, and sauces, it moderately increases viscosity to make products smoother and richer. It does not mask the original flavor of raw materials (e.g., preserving the sweetness of fruit juices or the aroma of sauces).

3. Application Scenarios: Covering Multiple Food Processing Categories

  • Baking Sector: As an anti-caking agent for flour and pre-mixed powders, it prevents caking during storage and mixing, ensuring uniform dough blending. This ultimately improves the fluffiness and taste consistency of baked products (e.g., bread, cookies).
  • Seasoning Sector: Added to powdered products like salt, chicken essence, and compound seasonings, it maintains particle looseness, preventing caking due to moisture absorption after opening (which affects usability) and ensuring accurate dosage for each use.
  • Beverage and Sauce Sector: It acts as a thickener in products such as fruit and vegetable juices, plant-based milks, and salad dressings. It makes liquids easier to adhere to surfaces (e.g., preventing sauce from dripping when spread) and enhances texture smoothness, solving the problem of "being too thin and lacking texture".

4. Procurement Logic: Why Prioritize Evonik SIPERNAT 22S?

The selection of food-grade silica dioxide should focus on three core dimensions: "safety compliance", "functional adaptability", and "strong stability" — and Evonik SIPERNAT 22S precisely meets these requirements:

  • Safety Aspect: It has obtained food-grade certifications from multiple countries/regions and is produced under a strict quality control system, eliminating concerns about compliance risks.
  • Functional Aspect: The integration of "anti-caking + thickening" reduces the types of raw materials used in a single product, lowering formula complexity and costs.
  • Stability Aspect: Minimal performance variation between batches ensures consistent food quality across different production cycles, avoiding instability in product taste and shape caused by raw material fluctuations.

In summary, Evonik SIPERNAT 22S is not merely an "additive" but a "quality collaborator" in the food processing sector. It addresses practical production pain points (e.g., caking, uneven texture) and indirectly enhances consumers’ eating experience. Whether you are a large-scale food manufacturer or an entrepreneur focusing on niche categories, this raw material can lay a solid foundation for product quality and help build competitive differentiation in the market.
