Entrained air bubbles are agglomerated, and the larger bubbles rise to the surface of the bulk liquid more quickly. These anti-foaming agents collapse the foam and retard the formation of additional foam. Colorants and Auxiliaries Invariably, the resulting foam impairs product properties in many different ways and greatly disrupts the process flow. endstream KJ"#zMCW?\3ngMM&0Y3\Kx#p)K As the microorganisms break down the nutrients, they release out the desired enzymes into the solution. 2. During such processes, anti-foaming agents are used as excessive foaming results in a reduced rate of processing, packaging and losses in the product volume. endobj This method is an alternative to the production of enzymes in liquid by submerged fermentation enzymes. 4 Resulting k L a values are different from those predicted from correlations for oxygen absorption into water.
