TERGITOL L-62 is used in foam control processes such as fermentation, food processing, food washing, water treatment, and metal working products. Advantages: Environment-friendly, high efficiency, no stain, low hygroscopicity, can satisfied defoaming requirement for most of non-silicone defoamer industries. You can read the details below. Federal government websites often end in .gov or .mil. The generation of foam during fermentation processes is caused by the existence of foam-active substances in the fermentation broth, escaping gas/air and turbulences within the fermenter. Fruit and vegetable washing and treating. Explanation: The antifoaming agents should not cause any problems in the extraction and purification of the product. Careers.

A defoamer is an antifoaming agent used to avoid the formation of foam in the industrial process liquids. The effects of antifoam addition are due to changes in culture density for P2000 and SB2121. The antifoaming agents in general use are silicone and polyoxyalkylene derivatives, and vegetable oil and animal oil derivatives.
