Study of the effect of DATEM. 4: Optimization of DATEM synthesis

DATEM synthesis was optimized to produce samples with high amounts of activ e components for breadmaking. Therefore, the Parameters of a standard proce dure were modified systematically, and the amounts of the major components in the resulting samples were determined by high-performance liquid chromat ography. Standard solutions of the three most active components were used f or identification and quantitation. Molten reactions between monoacylglycer ols and diacetyltartaric acid anhydride at low temperature (100 degreesC) h ad a positive effect on the formation of active components, especially afte r the addition of sodium acetate as a catalyst. The yield of active compone nts increased up to 88% compared to similar to 60% obtained by a standard p rocedure, The highest yield of the major components was obtained by using t etrahydrofuran as a solvent and pyridine as a catalyst. Under these conditi ons more than 90% of the DATEM sample were components with high baking acti vity.
