What effect does defoamer have on people in soymilk


If the defoamer is added within the scope permitted by the state, it is not harmful to health. If it is excessive, it is harmful. If industrial defoamer is added, it is harmful.


Selection method of defoamer:


1. Insoluble or insoluble in foaming solution. To dissolve the foam, defoamer should be concentrated and concentrated on the bubble film. In the case of foam breaker, it should be concentrated and concentrated in an instant, and in the case of foam suppression, it should always be kept in this state. Therefore, the defoamer is supersaturated in the foaming solution, and only insoluble or insoluble can it easily reach supersaturated state.


Insoluble or insoluble, it is easy to gather at the gas-liquid interface, it is easy to concentrate on the bubble membrane, and it can play a role at a lower concentration. The antifoam used in water system, the molecule of active component, must be strong hydrophobic and weak hydrophilic, the HLB value is in the range of 1.5-3, the best effect is.


2. The surface tension is lower than that of foaming liquid. Only when the force between defoamers is small and the surface tension is lower than that of the foaming solution, the defoamer particles can be immersed and expanded on the bubble membrane. It should be noted that the surface tension of foaming solution is not the surface tension of solution, but the surface tension of foaming solution.


3. It has a certain degree of affinity with foaming solution. Since the defoaming process is actually the competition between the rate of bubble collapse and the rate of foam formation, defoamers must be dispersed rapidly in the foaming solution so as to play a role in the wider range of foaming liquid.


In order to make the defoamer diffuse quickly, the active components of defoamer must have a certain degree of affinity with the foaming solution. The active components of defoamer are too close to the foaming solution, which will dissolve; too sparse and difficult to disperse. Only when intimacy is appropriate, the effect will be good.
