Core Functions & Applications
Key Functions
1. Superior Anti-Caking Protection: Its unique porous microstructure effectively prevents particle agglomeration caused by moisture absorption during storage and transportation. This ensures that your powdered food products remain free-flowing and maintain consistent quality throughout their shelf life.
2. Optimized Flow for High-Speed Processing: Reduces inter-particle friction and static electricity to deliver smooth, consistent powder flow. This is essential for high-speed automated filling lines, where it helps minimize weight variations and improve production efficiency.
3. Neutral & Safe Formulation: When used within regulatory limits, ZLSIL-T38A does not react with food ingredients or alter the nutritional value, flavor, color, or texture of your products. Its excellent dispersion properties ensure uniform distribution throughout the food matrix.
Primary Applications
Perfect for high-purity and high-compliance powdered food production, including:
• Dairy Products: Whole milk powder, skim milk powder, whey protein powder, and formulated milk powders
• Infant & Toddler Foods: Infant formula milk powder and complementary food powders
• High-End Food Ingredients: Premium baking mixes and artisanal compound seasonings
• Other Categories: Dehydrated egg products, nutritional supplements, and compound food additives
