Defoamer, also known as defoaming agent, is a food additive that reduces surface tension, inhibits foam generation or eliminates foam that has been generated during food processing. There are 7 kinds of defoamers approved for use in China, such as emulsified silicone oil, higher alcohol fatty acid ester compound, polyoxyethylene polyoxypropylene pentaerythritol ether, polyoxyethylene polyoxypropanolamine ether, polyoxypropylene glycerol ether and polyoxypropylene polyoxyethylene glycerol ether, polydimethylsiloxane, etc.
Physical properties
1. Fast defoaming and good foam inhibition performance.
2, does not affect the basic properties of the foaming system.
3. Good diffusivity and permeability.
4, chemical stability.
5, no physiological activity, no corrosion, non-toxic, no adverse side effects, non-flammable, non-explosive, high security.
