HIFULL® Silica Food Additive in Food

Fumed silica is a non-toxic, harmless, and pollution-free nano inorganic material that can be used as a food additive in food production. In the production and transportation of powdered food, factors such as environmental humidity, air exposure, and compression can lead to clumping and moisture absorption of ingredients containing lactose and proteins.

Fumed silica can be uniformly dispersed on the surface of solid food particles, forming a barrier that prevents direct contact between food particles and reduces their interaction forces, thus maintaining their free flowability. At the same time, it acts as a desiccant by adsorbing moisture in the gaps between particles, effectively reducing the potential for moisture absorption by food powder and slowing down the process of moisture absorption. This helps prevent clumping from occurring.

Why add fumed silica to Food?

Anticaking: Fumed silica, with its high specific surface area, when uniformly dispersed on the surface of particles, can isolate the moisture within the particles and absorb ambient moisture, preventing the formation of lumps in food during storage. Learn More

Flow aid: Fumed silica can envelop individual powder particles, acting as a barrier that reduces the direct contact between food particles and weakens the interaction forces. This effect, combined with the isolation of moisture within the particles, promotes a “rolling ball” effect, improving flowability.
