What we are introducing today is a kind of food additive that can prevent these dry powder foods from agglomerating and is harmless to the human body-fumed silica.

Every time you mention food additives, the question is sure to come: Is it toxic? Are there any side effects? Will you gain weight when you eat it?

Go straight to the answer: non-toxic, no side effects, will not gain weight, you will be discharged directly out of the body. (Of course, there must be a premise. Regular merchants of conscience add the amount according to national food standards. After all, it ’s not good to eat too much!)

The scientific answer is: through the consumption of silicon dioxide used as an additive into the human body, the weak alkali cavity environment, the strong acid stomach acid environment, and the weak acid intestinal environment do not decompose or absorb them, and are finally discharged together with feces.

Fumed silica is a colorless, odorless and non-toxic ultrafine inorganic new material, which is widely used in people's production and life. As a food additive, the main role of fumed silica is to prevent agglomeration of powdered food and improve its fluidity, thereby maintaining the good appearance of powdered food. And for powder foods from production, processing to transportation throughout the industrial chain, this characteristic will bring a great improvement in efficiency.

The reason why fumed silica can produce such amazing effects in powder foods is mainly due to its two major characteristics:
1. Have a large specific surface area. This property can make it wrapped on the surface of the powder material and play a role in spacing the powder particles, thereby preventing adhesion and promoting the free flow of powder food.
2. Has strong adsorption. The specific structure of fumed silica can promote its absorption of oil and grease on the surface of powders, thereby reducing the adhesion between powders.

Because of its characteristics, fumed silica has been widely used in powdered foods such as milk powder, coffee, and seasonings, which can prevent powdered food from agglomerating, facilitate transportation, and increase taste. Therefore, when you pour a cup of delicious milk and see the uniform and smooth milk powder particles, don't forget that there is the credit for the fumed silica.
