With a minimum silicon dioxide purity of 98% and a fine particle size distribution optimized for direct consumption, this product ensures a smooth, grit-free experience in all approved food applications.

Core Functions & Applications
Key Functions
1. Effective Anti-Caking for Direct-Consumption Products: Prevents powder agglomeration during storage and transportation, ensuring that your products remain free-flowing and easy to use for consumers. This is particularly important for products that are consumed directly without further processing.
2. Improved Flow for Accurate Dosing: Enhances powder flow characteristics to ensure consistent dosing and mixing. This helps consumers achieve uniform results when preparing beverages or food products at home.
3. Superior Sensory Experience: The ultra-fine particle size and excellent dispersion properties ensure that ZLSIL-W50S dissolves completely without leaving a gritty residue or altering the flavor of your products. This maintains the premium sensory experience that consumers expect from direct-consumption food products.
Primary Applications
Specifically designed for direct-consumption powdered food products, including:
• Dairy Products: Milk powder, whey protein powder, and formulated milk powders
• Solid Beverages: Meal replacement shakes, high-protein powders, and fruit and vegetable powders
• Infant & Toddler Foods: Infant complementary food powders
• Other Categories: Nutritional fortifiers and compound food additives for direct consumption
Product Advantages
