White carbon black, as an inorganic material, has been widely used in the food industry due to its unique physical and chemical properties. However, its safety has always been a focus of public and regulatory attention. In recent years, with the continuous deepening of scientific research, the application value and safety of white carbon black in the food industry have been more comprehensively evaluated.

The main use of white carbon black in the food industry is as an anti caking agent and clarifying agent. It can prevent powder clumping in food, such as sugar, salt, milk powder, and spices, thereby extending the shelf life of the product and improving its quality. In addition, white carbon black can also be used for clarification treatment of beverages, improving the transparency and appearance quality of products. For example, in the production process of wine and juice, white carbon black can adsorb suspended particles, making the beverage clearer.


From a safety perspective, white carbon black is a non-toxic and odorless inert substance. It is insoluble in water and most organic solvents, and does not undergo chemical reactions with ingredients in food. Therefore, the use of white carbon black in food is usually strictly limited to ensure its safety. According to the Codex Alimentarius Commission and national food safety regulations, the maximum amount of white carbon black used in food is generally not more than 20 grams per kilogram of food.


In recent years, some studies have further confirmed the safety of white carbon black in food. For example, animal experiments have shown that white carbon black is almost not absorbed in the body, and most of it is excreted through feces, so the risk to human health is extremely low. In addition, the nanoparticles of white carbon black have also received widespread attention. Although nanoparticles may have higher biological activity, current research results indicate that white carbon black nanoparticles used in food do not have significant effects on human health at normal doses.


However, the safety of white carbon black still needs to be continuously monitored and evaluated. With the development of nanotechnology, the particle size and surface properties of white carbon black may change, thereby affecting its behavior and potential risks in vivo. Therefore, the food industry and regulatory agencies need to work closely together to ensure that the use of white carbon black complies with the latest scientific standards and safety requirements.


In short, white carbon black has important application value in the food industry, and its safety has been scientifically verified and regulated. In the future, with the advancement of technology and strengthened regulation, white carbon black will continue to provide support for the development of the food industry while ensuring the health and safety of consumers.
