Diacetyl Tartaric Acid Ester of Mono- and Diglycerides (DATEM)
What is DATEM?
DATEM is an emulsifier used in bread making to strengthen the dough during processing. It helps improve texture and increase volume in a variety of products. Classified as an emulsifier, DATEM is derived from plant sources.
Even though it is characterized as an emulsifier, its function is not completely understood. It functions at the air/water interface within gluten proteins and flour lipids to improve gas-holding capacity of the dough.1 This provides a stronger dough that can be processed in a high-stress system, and a finer crumb grain with higher bread volume. It mainly interacts with gluten proteins to strengthen the dough, so it is redundant to use in gluten-free doughs.2
DATEM is naturally derived from vegetable sources, e.g. soybean oil. It is made by reacting diacetyl tartaric anhydride with mono- and diglycerides.
- Interacts with wheat gluten to strengthen its structure in yeast raised dough, contributing to tolerance towards variation in flour quality
- Creates better dough elasticity, resulting in better oven-spring and loaf volume, contributing to tolerance towards process variation
- Provides partial gluten replacement
- Excellent fat distribution, resulting in smaller cells, a more uniform structure and a smoother crumb texture
- Reduces fat usage (up to 20%) in biscuit formulas
- Replaces Lecithin
- Improves the volume of non-wheat flour inclusions3
Powder DATEM can be used at 0.25 to 0.5% (flour weight) at the mixer with flour or minor ingredients. The liquid form can be added along with the oil/fat.
