What is antifoam agent in fermentation?
Antifoaming agents are added to prevent or counter the foam generation in the formulation. ... Commonly used antifoaming agents are certain alcohols (cetostearyl alcohol), insoluble oils (castor oil), stearates, polydimethylsiloxanes and other silicones derivatives, ether and glycols (Karakashev and Grozdanova, 2012).
Examples of defoaming agents are 2-octanol, Oleic acid, paraffinic waxes, amide waxes, sulfonated oils, organic phosphates, silicone oils, mineral oils, and dimethylpolysiloxane.
Answer:
Explanation:
Concept:
By converting starch or sugar to alcohol or an acid anaerobically, fermentation is a metabolic process that is enzyme-catalyzed and releases energy. Zymology is the field of study that studies fermentation.
Solution:
To stop or reduce foam development in the formulation, antifoaming chemicals are included. Some alcohols, such as cetostearyl alcohol, insoluble oils, such as castor oil, stearates, polydimethylsiloxanes and other silicone derivatives, ether, and glycols are frequently used antifoaming agents (Karakashev and Grozdanova, 2012).
2-Octanol, Oleic acid, paraffinic waxes, amide waxes, sulfonated oils, organic phosphates, silicone oils, mineral oils, and dimethylpolysiloxane are a few examples of defoaming agents.
