摘要

An antifoaming agent for fermentation, which comprises (A) a reaction product obtained by the addition polymerization of 50 to 250 moles of ethylene oxide and propylene oxide (the molar ratio of ethylene oxide to propylene oxide = 1:1 to 1:4 ) to 1 mole of a mixture composed of an oil or fat and a polyhydric alcohol containing at least three hydroxyl groups; and (B) a fatty acid, an alcohol, a polyoxyalkylene polyhydric alcohol ether, a polyoxyalkylene alkyl ether, a polyoxyalkylene fatty acid ester, a polyoxyalkylene alkyl ether fatty acid ester and/or a polyoxyalkylene polymer. The above antifoaming agent has both foam-breaking effects and foam-inhibiting effects so that it has excellent antifoaming effects and does not adversely affect the fermentation production.
