Food grade silica, also known as silicon dioxide, is a vital additive widely used in the food and health industries for its anti-caking, flow-enhancing, and adsorption properties. It is a form of crystalline silica that meets stringent purity and safety standards, ensuring it is safe for human consumption. Shandong Zhonglian Chemical Co., Ltd. (山东中联化学有限公司) is a leading manufacturer specializing in premium food grade silica, offering high-purity silicon dioxide products that comply with international food safety regulations such as GB 25576-2020 and FDA standards.

Unlike industrial silica, food grade silica has extremely low heavy metal content, making it suitable for use in food and pharmaceutical applications. Its crystalline structure is carefully controlled to avoid health risks associated with harmful forms of silica. As silicon and silicium compounds, food grade silica plays an essential role in improving the quality and shelf life of food products, while also supporting health supplements. This article explores the key advantages, product specifications, and applications of Shandong Zhonglian's silica products, highlighting why they are the best choice for businesses.

Shandong Zhonglian's food grade silica offers several advantages that distinguish it from competitors. First and foremost, the silica boasts a high purity level with silicon dioxide content of ≥99%, ensuring excellent performance in food and health applications. The heavy metal residues, including lead and arsenic, are maintained well below international safety limits, with lead ≤0.1 mg/kg and arsenic ≤1 ppm, providing peace of mind for manufacturers and consumers alike.

The company utilizes advanced molecular-level production technology, which enhances the silica's anti-caking and flow properties. This results in superior dispersibility and adsorption efficiency, essential for maintaining product quality during processing and storage. Additionally, Shandong Zhonglian offers customizable particle size ranges from 2 to 250 micrometers to meet diverse application needs, from powdered supplements to complex food formulations.

With a stable production capacity supported by an intelligent manufacturing line capable of producing tens of thousands of tons annually, Shandong Zhonglian ensures consistent supply and quality control. This reliability makes them a trusted partner for global businesses seeking high-quality silica additives.

The food grade silica from Shandong Zhonglian is presented as a white, fluffy powder with a particle size customizable between 2 to 250 microns. The product maintains a pH range of 6.0 to 8.0 in a 10% aqueous suspension, making it compatible with a variety of food matrices. The drying loss is controlled to ≤7.0% at 105°C over 2 hours, ensuring product stability and low moisture content.

Typical application dosages range from 0.1% to 1%, depending on the specific use case. The anti-caking effect of the silica can last up to 24 months under proper storage conditions. Packaging options include 10, 15, or 20 kg valve paper bags or woven bags, with customization available to suit client requirements. The company offers fast delivery with stock items shipped within 5-10 days and custom orders fulfilled in 15-20 days. Free samples are available for quality assessment.

These specifications align with major international standards such as GB 25576, USP, FCC, and FDA, underscoring the product's compliance and suitability for global markets. To explore the full range of their silica products and detailed specifications, please visit the Products page.

Food grade silica by Shandong Zhonglian is predominantly used as an anti-caking agent in food and dietary supplements, where it prevents clumping and improves powder flowability. This ensures consistent quality and dosage accuracy in powdered foods, spices, and nutraceutical products. Its adsorption capacity also aids in moisture control, extending product shelf life without compromising safety.

In health industries, silica serves as an inert carrier for active pharmaceutical ingredients, contributing to better formulation stability. The non-toxic nature of this silicon dioxide makes it suitable for inclusion in tablets, capsules, and powdered supplements. Furthermore, its use is safely approved by regulatory authorities globally, making it a preferred choice for manufacturers aiming for high-quality, compliant products.
