Fumed Silica in Food Application
Each morning, a cup of coffee makes us refreshing before getting into one-day’s busy work; each evening, a cup of milk makes us relaxed and comfortable to get into good sleep ...... nowadays in high-speed busy society, health and nutrition are necessary.
If you see caked coffee powder or milk powder as below, will it ruin your beautiful day?
caked coffee powder and milk powder
Caked powder looks bad, you may wonder whether it’s expired or not, then lose your appetite. We want quality life, the same with our food, especially the appearance of food. And fumed silica has the function to avoid caked powders, it’s an safe food additive.
When it comes to food additives, you may wonder: is it innoxious? Does it have side effect? Will I get fat having this?
Here are the answers: Fumed silica is innoxious with no side effect and you will not get fat because it will be expelled out of your body. When you have some food which is added the food grade fumed silica, the human weak base cavity can’t not digest or absorb it, neither gastric acid or intestinal weak acid, so it will be expelled out with human waste.
Fumed silica is colorless, odorless and non-toxic. It’s a superfine inorganic nano material, it’s applied in many applications. When fumed silica is added into food, it can improve free flow property and anti-caking properties of powders, which have a positive effect on the storage and transport of the end products.
The magic fumed silica created in powder products comes from its two properties:
1. Large surface area. Large surface area enables fumed silica to cover all around the powder products, it can separate particles, so to avoid viscosity and to ensure excellent flowing property.
2. Strong adsorptivity. The special structure of fumed silica allows it to adsorb the oil and water on the surface of powders, then decreases viscosity.
