Dry powder food additive----fumed silica

What we are introducing today is a kind of food additive that can make these dry powder foods not agglomerate and harmless to human body - fumed silica.
When it comes to food additives, everyone must have a question: Is it toxic? Are there any side effects? Will eating make you gain weight?

Let’s go directly to the answer: it is non-toxic, has no side effects, will not gain weight, and will be directly excreted by you. (Of course, there is a premise for everything. Conscientious and regular merchants add the amount according to the national food standard. After all, it is not good to eat too much of anything!)

The scientific answer is: Silica is used as an additive into the human body through consumption, and it will not be decomposed or absorbed in the weak alkali cavity environment, strong acid gastric acid environment, and weak acid intestinal environment, and finally excreted with the feces.

Fumed silica is a colorless, odorless and non-toxic ultra-fine inorganic new material, which is widely used in people's production and life. As a food additive, the main function of fumed silica is to prevent powder food from caking and improve its fluidity, so as to maintain the good appearance of powder food. Moreover, for the entire industrial chain of powder food from production, processing to transportation, this characteristic will bring about a great improvement in efficiency.

The reason why fumed silica can produce such amazing effects in powdered food is mainly due to its two major properties:

1. Has a large specific surface area. This feature enables it to wrap on the surface of the powder material and act as a spacer between the powder particles, thereby preventing adhesion and promoting the free flow of the powder food.

2. Has strong adsorption. The specific structure of fumed silica can promote it to absorb oil and moisture on the surface of the powder, thereby reducing the adhesion between the powders.

It is precisely because fumed silica has such characteristics that it has been widely used in various powder foods such as milk powder, coffee, and seasoning. So, when you pour a cup of delicious milk and see the uniform and smooth milk powder particles, don't forget that there is a credit for fumed silica! Yichang Hui silicon-rich material produces hydrophilic and hydrophobic fumed silica.
