What is "datem"

DATEM (diacetyl tartaric acid ester of mono- and diglycerides, also E472e) is an emulsifier primarily used in baking to create a strong gluten network in dough. It is added to crusty breads, such as rye to impart a springy, chewy texture, as well as in the production of biscuits, coffee whiteners, salsa con queso, ice cream, and salad dressings.
