CA 2358556

The invention provides a mixture comprising diacetyl tartaric acid esters on mono- and diglycerides based on C12 to C22 fatty acids which mixture comprises diacetyl tartaric acid glycerol monoesters containing: (A) one fatty acid group, one diacetylated tartaric acid monoester group and a free hydroxyl group and (B) one fatty acid group and two diacetylated tartaric acid monoester groups in which the molar percentages of (A) and (B) obtained by a specific NMR-technique which satisfies certain defined parameters. Preferably this mixture is based on mono- and diglycerides of substantially saturated C16 and/or C18 fatty acids. The invention further provides processes for preparing the mixture defined above and the use thereof as emulsifier, dough conditioner, in flour and in bakery improvers for yeast-leavened baked products. Also the invention provides baked products in which the mixture defined above has been incorporated.

L'invention concerne un mélange comprenant des diacétyl-esters d'acide tartrique de mono- et diglycérides d'acides gras en C12-C22, lequel mélange comprend des monoesters diacétyl-tartriques de glycérol contenant (A) un groupe d'acides gras, un groupe monoester tartrique diacétylé, et un groupe hydroxyle libre, et (B) un groupe d'acides gras et deux groupes monoester d'acide tartrique diacétylé, dans lesquels les pourcentages molaires de (A) et (B), obtenus par une technique d'imagerie par résonance magnétique nucléaire, correspondent à certains paramètres définis. De préférence, ce mélange est à base de mono- et diglycérides d'acides gras essentiellement saturés, en C16 et/ou en C18. L'invention concerne en outre des procédés de préparation du mélange ci-dessus décrit et l'utilisation de celui-ci, en tant qu'émulsifiant et agent d'amélioration de la panification, dans la farine et dans des dispositifs d'amélioration de la panification destinés à des produits de boulangerie à base de levure. De même l'invention concerne de tels produits de boulangerie dans lesquels on a incorporé le mélange décrit ci-dessus.
