Fermcap S possible precautions and Fermcap AT
Posted: Fri Jun 29, 2012 9:25 am
We haven't talked much about the different Fermcap that is available. Seems like people are switching to Fermcap AT (canola oil) which does not contain silicone. Supposedly there was a FDA statement about Fercap S (silicone) should not be used in unfiltered beers. That would be us. I cant think of many homebrewers who filter beers. Denny Conn spoke with Birko and this is what was said....

Here is the spec from the manufacture of Fermcap. Notice it doesnt say a word about FDA but does indeed say:

Something to think about.
Here are some interesting links discussing this issue further. From a personal standpoint when racking the stuff always sticks to the sides of the fermenter. Im not exactly worried about using the Fermcap S but just because of this thread Im going to look for the AT canola oil based version."Brewers should not use silicone-containing antifoam for unfiltered beers. The FDA allows active silicone to be used up to 10 parts-per-million (ppm) but stipulates that the silicone must be removed prior to packaging by either filtration or centrifugation. In the case of unfiltered beers, use a food grade, non-silicone antifoam. We sell a food grade, canola oil based antifoam that works well for this purpose and has an added benefit of being yeast-friendly at the same time. Look for my article on antifoams in the brewery in the July/August issue of The New Brewer. Please contact me directly if you would like to discuss this or any other matter further."

Here is the spec from the manufacture of Fermcap. Notice it doesnt say a word about FDA but does indeed say:
FermCap is a unique emulsion of an extremely effective surface-active agent, which prevents foam formation by reducing surface tension. It is classified as a "process aid" because of its novel feature of being completely removed from the beer under normal processing conditions.
