ABSTRACT:
Troublesome foaming in the fermentation of yeast is suppressed by the addition of polyglycol ethers which are derived from saturated and monounsaturated C.sub.16 -C.sub.18 fatty alcohols and which contain on an average of from 1 to 4 ethylene and/or propylene glycol ether groups. Preferred defoamers contain oleyl and cetyl alcohol residues in a ratio of from 3:1 to 1:1, and on average 2 ethylene glycol ether groups. The defoamers do not inhibit yeast growth or lead to premature softening and liquefaction of the compressed yeast.
