Precipitated Silica Food Anti Caking Agent 7631-86-9 Food Agent Wanted

SDF series for food grade is white granule or fluffy powder with high purity and excellent fluidity. It is characterized as moisture absorption and flow promotion. The product is used in various powdery food to improve fluidity of powder so as to prevent caking or improve the diffusion ability of dry power in liquid. Therefore, it can play the good role in antimildew application. The product is mainly used in food caking inhibiter, thickening agent, stabilizer, essence and spice desiccant and clarification filter aid, etc.
