摘　　要：以二甲基硅油为原料,配制出有机硅复合乳液消泡剂,将其应用于模拟味精发酵过程中的发泡环境,并同现用的发酵消泡剂进行了对比检验。结果表明,有机硅复合乳液消泡剂具有消泡速度快、用量少的特点,同时能提高产能和发酵单位,对菌种无毒害作用,应用效果优于现用的聚醚消泡剂、植物油类消泡剂和有机硅消泡剂。Silicone emulsion defoamer was prepared using dimethly silicone oil as the raw material. It was compared with common fermentation defoamers in the monosodium glutamate fermentation process. The results showed that the silicone emulsion defoamer was more effective than the simple polyether defoamers, vegetable oil type defoamers or silicone - type defoamers. It had higher speed of defoaming, lower quantity required , and improved production capacity and fermentation units, with no poisoning effect on the bacteria. It was an ideal fermentation defoamer.
