    Introduction: emulsifier and dispersant are common substances in our industrial production What are the differences between emulsifier and dispersant? Is it harmful to eat emulsifier? These problems can be understood together with the small edition of Baibai safety net Emulsifier usually refers to surfactant Surfactant is a kind of substance When a small amount of surfactant is added into the solvent, the surface tension will be significantly reduced, and the interface state of the system will be changed, thus a series of functions such as wetting, emulsifying or demulsifying, dispersing or agglutinating, foaming or defoaming, solubilizing will be produced, so as to meet the application requirements Emulsifiers have the ability to interact with emulsified particles, so they can be added to the protected particles in the way of complexation, which can enhance the charge of the protected particles and the solvate film, and improve the stability of the system The emulsifier can reduce the interfacial tension between two phases and form a single molecular boundary film to stabilize the emulsion It can also form a space or electrostatic barrier layer, prevent emulsion particles from aggregated, and also stabilize the emulsion The elasticity of the interfacial film and the viscosity of the system are important factors for the stability of the emulsion The function of dispersant is to use wetting dispersant to reduce the time and energy needed to complete the dispersing process, stabilize the dispersed pigment dispersion, modify the surface properties of pigment particles, and adjust the movement of pigment particles, which is embodied in the following aspects: shorten the dispersing time, improve the luster, improve the coloring power and covering power, improve the color development and color matching, and prevent the floating and blooming To prevent flocculation and sedimentation What's the difference between emulsifier and dispersant? Dispersant refers to the substance dispersed in dispersion system For example, when salt is dispersed into water, water is the dispersant, salt water is the dispersing system and salt is the dispersing substance Emulsifier is to help the emulsion disperse Emulsifier can make some immiscible liquid merge into stable emulsion, and improve flavor and prolong shelf life in food processing Dispersant is to keep the solution in a stable state; continuous phase and dispersed phase are slightly different Is it harmful to eat emulsifier? The standard of food additives in China also allows emulsifier to be added into food If you eat too much emulsifier, it will do harm to the health of people with poor kidney function Therefore, you should pay attention to appropriate amount of emulsifier and not use it too much In general, the emulsifier in food is not excessive, but if it is suspected that the food safety detector can be used to detect the content, we should also have a deep understanding of food safety knowledge, so that we can understand the relevant problems of food emulsifier Editor in charge: he xianrob
