The food-grade silica from zhonglian-chem（zhongqi silicon） appears as a white, fluffy powder, designed for easy incorporation into various formulations. The particle size range is customizable from 2 to 250 microns, catering to different processing and performance needs. This broad range makes the silica suitable for applications requiring fine powders or coarser particles for enhanced flow and anti-caking properties.

Maintaining a silica content of at least 99%, the product ensures minimal impurities and high efficacy. The pH of a 10% suspension solution typically ranges from 6.0 to 8.0, which is neutral to slightly alkaline, making it compatible with most food and health product matrices. The moisture content is controlled to a drying loss of ≤7.0% at 105°C over 2 hours, preserving the powder's free-flowing nature and stability.

The recommended addition rate of this silica ranges between 0.1% and 1%, depending on the specific formulation requirements. Its anti-caking effectiveness remains stable for up to 24 months under proper storage conditions. This extended shelf life ensures that manufacturers can stock adequate inventory without concerns about product degradation or performance loss over time.

Food-grade silica plays a crucial role as an anti-caking agent in powdered food products, preventing clumping and improving flow properties during processing and packaging. It is widely used in powdered spices, coffee creamer, powdered milk, and other dry food ingredients to maintain product quality and ease of handling. The inert nature of amorphous silica ensures it does not react chemically with food components, preserving flavor and nutritional integrity.

Beyond food, silica is an essential additive in health supplements and pharmaceuticals. It helps maintain the free-flowing nature of powdered vitamins, minerals, and herbal extracts, facilitating accurate dosing and manufacturing efficiency. The low heavy metal content and high purity of zhonglian-chem（zhongqi silicon）’s silica make it particularly suitable for sensitive health applications where safety and compliance with FDA and USP standards are paramount.
