What is the effect of defoamer

Introduction: defoamer is used in both food industry and industrial production With such a wide range of applications, what's the effect of defoamer? Can defoamer be used? Please introduce it to you in the following Generally speaking, foam is a coarse dispersion of gas in liquid and belongs to gas-liquid heterogeneous system A gas-liquid dispersion with a bulk density close to that of a gas and not close to that of a liquid The gas-liquid dispersion is divided into "bubble dispersion" with less liquid and more gas, and "foam" with less gas and more liquid Foam can be defined as a stable gas in a liquid medium Foam is a dispersion system of gases in liquid Gas is separated from many bubbles by continuous phase liquid Gas is dispersed phase and liquid is dispersed medium Foam is a thermodynamically unstable system It can not be stable The thermodynamic instability of foam is due to the large decrease in the total surface area of the system after the bubble breaking, resulting in the reduction of the energy (free energy) of the system Defoamer, also known as anti foaming agent, will produce many harmful foam in the process of industrial production, and need to add defoamer Defoamer is to reduce the surface tension in food processing, inhibit foam to produce or eliminate froth food additives The defoamer that our country permits to use is emulsified silicone oil, high alcohol fatty acid ester complex, polyoxyethylene polyoxypropylene pentaerythritol ether, polyoxyethylene polyoxypropanol amine ether, polyoxypropylene glycerol ether and polyoxypropylene polyoxyethylene glycerin ether, poly two methyl silicon There are 7 kinds of oxyalkanes What's the function of defoamer? It's believed that defoamer has the function of breaking and defoaming, reducing the surface tension, dispersing the active ingredients into small particles, so that they can be easily dispersed in water and have better defoaming and antifoaming effect It is helpful for the combination of carrier and foaming system, easy to disperse into the foaming system, and the combination of the two, its own surface tension is low, it is helpful for foam suppression, and it can reduce the cost Make emulsification effect better Can defoamer be used? As long as the added defoamer is not excessive, it is harmless, but if it is excessive Like other food additives, they have a great impact on human body Therefore, it is OK to eat defoamer, but it depends on the content of defoamer in food We can learn more about food additives and defoamers through the detection of food safety detector, or through the understanding of food safety knowledge Editor in charge: he xianrob
