DATEM - Reference Information
| Application | diacetyl-tartaric acid monoglyceride is a food emulsifier and is present as a predominantly white or yellowish powdery solid. Commonly used in bread production in Europe, it can interact with protein, especially gluten, promote the formation of gluten-starch-fat network structure, and improve the stretch resistance and gas holding capacity of dough, it is beneficial to increase the volume of bread and improve the structure of bread. The molecule contains a large number of double acetyl, hydroxyl and other hydrophilic groups, which is conducive to maintaining the moisture of the dough and preventing the aging of the bread. |
| preparation | preparation of diacetyl tartaric acid monoglyceride: 1kgL-tartaric acid and 2.2kg acetic anhydride were pumped into a reaction kettle, add 5g of acetic acid and 10g of benzalkonium bromide, stir well, react at 75 ℃ for 2H to obtain an intermediate product containing diacetyl tartaric anhydride; Add 2.5kg of glyceryl monostearate to the intermediate, stir well, reaction was carried out for 3H at 110 ° C. Under vacuum of 0.08MPa. After completion of the reaction, the temperature was lowered and distilled to obtain 84.3% of final product. The content of diacetyl tartaric acid monoglyceride was 402, the acid value was 67, and the saponification value was. The physical and chemical indexes of diacetyl tartaric acid monoglyceride all meet the relevant requirements of food additive diacetyl tartaric acid monoglyceride GB25539-2010. |
| properties | milky white powder or granular solid, can be dispersed in hot water, can be miscible with oil, soluble in ethanol, organic solvents such as propylene glycol. |
| Use | for non-ionic food emulsifier, China can be used for whipping cream, bread, cakes and hydrogenated vegetable oil, the maximum use amount is 10g/kg; The maximum use amount is 5.0g/kg in the plant fat powder. |
| production method | tartaric acid reacts with acetic anhydride to form a solution of diacetyl tartaric anhydride and acetic acid, the acetic acid was distilled off under reduced pressure to obtain diacetyl tartaric anhydride, which was reacted with Molecular distillation monoglyceride at 120 ℃ to obtain the product. |
