Estimating the term…
A mixture contains diacetyl tartaric acid esters of mono- and diglycerides based on C12 to C22 fatty acids or 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 satisfy certain defined parameters. Preferably the mixture is based on mono- and diglycerides of substantially saturated C16 and/or C18 fatty acids. Processes for preparing the mixture defined above and the use thereof as emulsifier, dough conditioner, in flour and in bakery improves for yeast-leavened baked products are disclosed as are baked products in which the mixture defined above has been incorporated.
A mixture comprising diacetyl tartaric acid esters of mono- and diglycerides based on C12 to C22 fatty acids which mixture comprises diacetyl tartaric acid glycerol monoesters containing:
A process for preparing a mixture comprising diacetyl tartaric acid esters of mono- and diglycerides based on C12 to C22 fatty acids, said process comprising reacting molten diacetylated tartaric acid anhydride with molten C12 to C22 fatty acids partial glycerides comprising 60-99 wt % of monoglycerides, optionally under an inert atmosphere, at 135 to 175° C. for a reaction period from 0.5 to 30 minutes in the presence of an effective amount of a catalyst.
A process for preparing a mixture comprising diacetyl tartaric acid esters of mono- and diglycerides based on C12 to C22 fatty acids, said process comprising allowing molten mono- diglycerides containing 60 to 99 wt % of monoglycerides and solid diacetylated tartaric acid anhydride to react in a liquid phase, optionally under an inert atmosphere, at a temperature between 60 and 120° C. for a period of 5 to 30 minutes in the presence of an effective amount of an alkaline catalyst.
