Evonik Food Grade Silica: Innovative Solutions Driving Food Processing & Nutrition Upgrade

Created on 04.30

With the upgrading of global food consumption trends, the food industry has put forward more diversified requirements for functional additives, from clean label formulas to plant-based food, from personalized nutrition to sustainable production. As a global leader in synthetic amorphous silica technology, Evonik has more than 50 years of R&D and manufacturing experience, and has created a full range of food grade silica solutions with four major product lines: SIPERNAT®, ZEOFREE®, AEROSIL® and SIDENT®, which have become indispensable functional ingredients in the global food, animal nutrition and oral care industries.

Laboratory setting with food grade silica products

Evonik achieves precise customization of product performance through advanced precipitation and fumed production processes, to meet the unique needs of different food systems. For conventional powdered food anti-caking and flow aid needs, hydrophilic SIPERNAT® 22 S and 50 S can significantly improve powder fluidity with an addition amount of 0.5-2%, solving the agglomeration problem during storage and transportation; for high-humidity and high-fat powder systems, the hydrophobic SIPERNAT® D 17 can achieve excellent anti-caking effect at an ultra-low dosage of 0.1-0.5%, far lower than conventional hydrophilic products. The AEROSIL® food grade fumed silica series has ultra-high purity and extremely low impurity levels, which is perfectly suitable for formulas with sensitive ingredients, and provides excellent thickening and rheology control in liquid and semi-solid food systems. The ZEOFREE® series has excellent mechanical stability, which is suitable for production processes with high-shear mixing; the SIDENT® series is specially developed for toothpaste and oral care products, with tailored RDA and PCR values, covering all oral care formula needs.
