Regulations allow: According to the Chinese national standard GB 2760-1996, dimercaptoacetone is allowed to be used as a food flavoring agent. Usage limit (FEMA standard): Baked products: 7.5 mg/kg Meat products: 2.0 mg/kg Safety: Listed as GRAS (Generally Recognized As Safe) substance by the US Food and Drug Administration (FDA). Other uses: It is also used as the raw material of synthetic perfume and used in daily chemical essence. ============================================================================== synthetic route The detailed synthesis route of dimercaptoacetone is not clearly provided in the public information. But according to its chemical structure (2,5-dimethyl-2,5-dihydroxy-1,4-dithiane), its synthesis can usually be achieved through the following pathways: Starting materials: Acetone and hydrogen sulfide (or thiol compounds) are used as raw materials. Reaction pathway: Acetone reacts with hydrogen sulfide under acidic conditions to produce 2-mercaptoacetone. Oxidative coupling reaction occurs between 2-mercaptoacetone molecules, forming disulfide bonds (- S-S -), and ultimately cyclizing to form 2,5-dimethyl-2,5-dihydroxy-1,4-dithiane (i.e. dimercaptoacetone). Reaction conditions: Usually carried out under mild heating and inert atmosphere to avoid excessive oxidation. Purification: The product can be purified by recrystallization (such as using ethanol or acetone) to obtain high-purity white crystals. This synthesis route is a common "one pot method" or two-step method in industry, which complies with the production standards of food grade spices six Uses : used to mix meat essence and enhance the flavor of meat products Synonyms : Dimeric mercapto propanone;Dimeril mercapto propanone;2,5-Dimethyl-2,5-dihydroxy-1,4-dithiane; Molecular Structure :
