シリコーンオイル

食品・飲料分野における食品グレードのシリコーンオイルは、加工中に既存の泡を破壊し新たな泡の発生を抑えるポリジメチルシロキサン（PDMS）系消泡剤エマルションです。 PDMSは表面張力が非常に低いため、気液界面に広がって気泡を保持する薄膜を破壊します。有効成分10-50%のエマルションとして供給され、少ない添加量で機能するため、小型のドラム1本で大きな生産量に対応できます。

A defoamer knocks down foam that has already formed; an antifoam added up front stops it from building. A silicone emulsion does both, which is its edge over organic defoamers. The trade-off is dose discipline: silicone is so effective that an overdose can carry into the finished product and flatten foam you want, such as a beer head or whipped-dessert aeration. Dose to the minimum that controls process foam, and control the point of addition.

Typical duties are foam control in fermentation, vacuum evaporation and concentration, frying oils, and high-speed bottling and filling. Polydimethylsiloxane is permitted as a defoaming agent under food-additive regulations (for example 21 CFR 173.340 in the United States and E900 in the EU); confirm regulatory status for your application and jurisdiction. Match the emulsion's active level and viscosity to your process, and run a small trial to set the dose before scaling up.
