Can sulfur dioxide be used as food bleaching agent

Introduction: the chemical properties of sulfur dioxide are extremely complex Different temperatures can be used as aprotic solvent, Lewis acid, reductant, oxidant, redox agent, etc Can sulfur dioxide be used as food bleaching agent? Sulfur dioxide is the most common sulfur oxide Colorless gas with strong pungent smell One of the main air pollutants When a volcano erupts, it emits the gas, which in many industrial processes produces sulfur dioxide Since coal and oil usually contain sulfur compounds, sulfur dioxide will be generated during combustion When sulfur dioxide dissolves in water, it forms sulphurous acid (the main component of acid rain) If SO2 is further oxidized, sulfuric acid will be generated in the presence of catalyst such as nitrogen dioxide This is one of the reasons for concern about the environmental effects of using these fuels as energy Can sulfur dioxide be used as food bleaching agent? Sulfur dioxide can't be used to bleach food The bleaching mechanism of sulfur dioxide is to react with colored substances The ingredients of food have changed after being bleached by sulfur dioxide The residual sulfur dioxide will affect human body and cause damage when it comes close to human body after being used Sulfur dioxide is toxic to people If there is water and oxygen, it will react to form sulfuric acid, which is harmful At room temperature, sulfur dioxide reacts with hydrogen sulfide to form sulfur Under the condition of high temperature and catalyst, it can be reduced by hydrogen to hydrogen sulfide and carbon monoxide to sulfur Strong oxidants can oxidize sulfur dioxide to sulfur trioxides Only in the presence of catalysts can oxygen oxidize sulfur dioxide to sulfur trioxides It has the characteristics of spontaneous combustion and helplessness Liquid sulfur dioxide can dissolve organic compounds such as amines, ethers, alcohols, phenols, organic acids, aromatic hydrocarbons and so on It has certain water solubility, and reacts with water and steam to generate toxic and corrosive steam Many foods use bleach, so is it safe to bleach? In fact, if it is used according to the national regulations, it will not be dangerous Now the state has a food safety detector, which can quantitatively detect 50 parameters in the food on the spot So that we can eat more safe food, more food safety knowledge in the hundred safety net Editor in charge: he xianrob
