PQ Food-Grade Silica Series Products

1. PQ Corp's Neosyl GP: Multifunctional Liquid Carrier & Anti-Caking Core in Food Industry

As a basic model in PQ Corp's food-grade silica product line, Neosyl GP features synthetic amorphous silica as its core component, combining high-efficiency anti-caking performance and liquid carrying capacity. It serves as a key auxiliary material in food processing that balances stability and process adaptability. Its porous structure provides a high specific surface area, effectively adsorbing free moisture in the environment and breaking the adhesion between powder particles. Widely applicable to moisture-sensitive and caking-prone powdered foods such as milk powder, cocoa powder, and vegetable fat powder, it significantly enhances product fluidity and storage stability.

In terms of functional expansion, the liquid carrying property of this model is particularly prominent. It can convert liquid food additives, flavors and fragrances into free-flowing powder, which not only maintains the stability of active ingredients but also simplifies processing links such as mixing and metering. Complying with major global food additive standards including FDA 21 CFR (US) and GB 25576-2020 (China), it is free from heavy metal and microbial contamination risks. With a maximum usage level of up to 15g/kg in egg powder, solid beverages and other products, it fully meets large-scale production needs.

2. PQ Corp's Neosyl GP FF: Low-Dust Anti-Caking Solution for Fine Powders

Tailored to the processing needs of high-value-added fine powdered foods, Neosyl GP FF adopts a special surface treatment process. While inheriting the core anti-caking performance of the GP model, it achieves low-dust upgrading. Its narrow particle size distribution design (particle size parameters adapted to the adsorption needs of fine powders) greatly reduces dust emission during production, which not only improves the safety of the operating environment but also reduces material loss. It is especially suitable for products with small particle sizes and high added value such as chili powder, powdered flavors, and health product raw materials.

The core advantage of this model lies in the dual characteristics of "high-efficiency anti-caking + low-dust compatibility". By optimizing the pore structure and surface energy, it can achieve long-term anti-caking effect with only 50% of the addition amount of traditional anti-caking agents. The low-dust design is compatible with the closed processing needs of automated production lines, avoiding dust explosion risks and cross-contamination issues. Covering strict standards such as EU EC No 852/2004 in terms of compliance, it is the preferred auxiliary material for high-end fine food manufacturing.

3. PQ Corp's Neosyl GP LC: Stabilizing Agent for Liquid Food Systems

Specifically designed for liquid and high-humidity food systems, Neosyl GP LC features "low viscosity impact + high-efficiency adsorption" as its technical highlights, breaking the application boundary that traditional anti-caking agents are mostly limited to dry powder systems. Its special colloidal silica structure does not cause viscosity accumulation after dispersion in liquids and can stably exist in products such as lactic acid bacteria beverages, flavor syrups, and paste fillings. By adsorbing trace metal ions and oxidation products in the system, it delays food browning and flavor deterioration.

In terms of process adaptability, this model can form a synergistic effect with thickeners such as xanthan gum and carrageenan, which does not interfere with product texture but also enhances emulsion stability and avoids stratification and sedimentation. Complying with global food contact material safety regulations, it can be safely used in special foods such as maternal and infant formula foods. Its characteristics of no peculiar smell and no impact on taste make it irreplaceable in high-end liquid food processing.

4. PQ Corp's Neosyl TS: Long-Lasting Anti-Caking Benchmark in High-Humidity Environments

Developed by PQ Corp for high-humidity storage and transportation scenarios, Neosyl TS is a high-efficiency anti-caking agent. Relying on unique surface modification technology, it can still maintain stable anti-caking performance in high-humidity environments (relative humidity ≥85%), solving the storage problem of foods in tropical regions and high water activity foods. Its three-dimensional network pore structure can realize rapid adsorption and fixation of moisture. With an addition amount of only 2-5g/kg in salt, solid compound seasonings and other products, it can effectively prevent caking caused by pressure.

The core technological breakthrough of this model lies in the humidity-responsive surface design. When the environmental humidity rises sharply, the surface silanol groups can quickly combine with water molecules to form a stable water film, preventing powder particles from crystal transformation due to moisture absorption. Meanwhile, complying with the FAMI-QS certification standard, it can be cross-applied in the feed and food fields. Its high-temperature stability (withstanding processing temperature ≤200℃) also makes it suitable for heat-processed powdered foods such as baking premixes.

5. PQ Sorbsil R92: Efficient Impurity Removal & Safety Guarantee for Edible Oil Refining

As a food-grade silica hydrogel product specially developed by PQ Corp for the oil industry, Sorbsil R92 takes "precision impurity removal + ecological compatibility" as its core advantages and has become a benchmark auxiliary material for global edible oil refining enterprises. Its special formula containing citric acid and high specific surface area of 150-600 m²/g form a synergistic effect, which can efficiently adsorb polar impurities in crude oil such as phospholipids (especially non-hydratable phospholipids), metal ions (Fe, Cu), aflatoxin B1 and benzo(a)pyrene.

In terms of process value, this model can reduce the dosage of activated clay by 20-30% when used in combination with it, significantly reducing solid waste discharge while improving filtration efficiency and oil purity. Its acidic property with pH 2.2 makes it especially suitable for refining vegetable oils with high phospholipid content. It has stable performance at temperatures ≤200℃ and can retain the natural nutrients and flavors of oil products. Complying with FDA 21 CFR 172.480, EU food safety standards and China GB 25576-2010, it has no GHS hazardous component classification, and wastewater can directly enter the traditional treatment system, achieving dual optimization of environmental protection and efficiency.

6. PQ Synsilca 300: Versatile New Option for Food-Grade Silica Gel

As a featured model of PQ Corp's food-grade silica, Synsilca 300 is based on high-purity amorphous silica and combines multiple functions of anti-caking, flow aiding and adsorption, adapting to the processing needs of various food categories. Its optimized particle size distribution (referring to the particle size characteristics of similar food-grade silica gel) and pore structure can quickly disperse in powdered foods to form an anti-caking network, effectively preventing hard caking of milk powder, dehydrated protein products and other products during storage.

The differentiated advantage of this model lies in its carrying capacity for fat-soluble components. It can be used as a carrier for active substances such as essential oils and fat-soluble vitamins, realizing uniform dispersion and stable preservation of active ingredients in nutritional supplements and functional solid beverages. Complying with the Global Standard for Food Additives (GSFA), its heavy metal content is less than 0.1ppm. With a maximum usage level of up to 20g/kg in spices and compound seasonings, it provides a safe and reliable multifunctional auxiliary material option for the food industry.
