Can silicon dioxide be used as food additive?
In the morning, when we are ready to start the day's work, we will have a cup of coffee, and the whole person will be full of vitality; Make a glass of milk before going to bed, and sleep with milk fragrance. In the modern high rhythm life, healthy life and nutrition supplement are essential. But when you see caked milk powder and caked coffee, will it affect your appetite?
At the moment, it is believed that the first reaction of many people may be whether the milk powder has detiriorated, and the appetite is estimated to have lost most of it. In this era of constantly improving high-quality life, the appearance and appearance of food are also indispensable.
What we are talking about today is a kind of food additive that can prevent these dry powder foods from caking and is harmless to human body ---- silicon dioxide.
When it comes to food additives, we are sure that the question arises: Is it toxic? Are there any side effects? Will you gain weight after eating?
The answer is: non-toxic, no side effects, no obesity, you will be directly discharged into the body. (Of course, everything should have a premise. Conscientious and regular businesses should add according to the national food standard.)
The scientific answer is: the additives that enter the human body through eating are silica, which will not be decomposed or absorbed by weak alkaline cavity environment, strong acid stomach acid environment, and weak acid intestinal environment, and will be discharged with feces
Silica is a colorless, tasteless, 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 silicon dioxide is to prevent powdered food from caking and improve its fluidity, so as to maintain the good appearance of powdered food. Moreover, for the whole industrial chain link of powdered food from production, processing to transportation, this feature will bring great improvement in efficiency.
The reason why silica(SiO2) as food additive can produce such a magical effect in powdered food is mainly due to its two characteristics:
1. It has a large specific surface area. This feature can enable it to wrap on the surface of powder material, play a role in spacing between powder particles, thus preventing adhesion and promoting the free flow of powder food.
2. It has strong adsorption. The special structure of silicon dioxide can promote its absorption of oil and water on the surface of the powder, thus reducing the adhesion between the powder.
It is precisely because silica has such characteristics that it has been widely used in milk powder, coffee, spices and other powder foods. So, when you pour a cup of delicious milk and see the even and smooth milk powder particles, don't forget that there is silica in it
