FermCap AT
FermCap AT is a unique emulsion of an extremely effective surface active agent Dimethylpolysiloxane which prevents foam formation by reducing surface tension.
FermCap AT is classified as a "Process Aid" because of its novel feature of being completely removed from the beer under normal processing conditions. It is adsorbed onto the surface of the yeast, vessel walls and filter media.
Analytical techniques accurate to 0.005 ppm cannot detect FermCap AT in finished beer.
