Mono- and diacetyl tartaric acid esters

International Numbering System (INS) for Food Additives: 472e
Food additives Europe numbers: E472e 

Mono- and diacetyl tartaric acid esters of mono- and diglycerides of fatty acids, also known as DATEM (diacetyl tartaric acid ester of mono- and diglycerides) or E472e, is a food excipient used primarily in baking applications. Here's a breakdown of its components, functionalities, and safety considerations:

Components:

  • Mono- and diglycerides: As described previously, these are emulsifiers derived from fats and oils.
  • Tartaric acid: A naturally occurring organic acid found in fruits like grapes.
  • Acetic acid: Another organic acid commonly used as vinegar.

Function in Food:

DATEM functions primarily as a dough strengthener. It works by:

  • Emulsifying gluten and starches: It helps create a more stable gluten network within dough, leading to improved elasticity and structure.
  • Modifying starch behavior: It can influence starch gelatinization during baking, impacting crumb texture and volume.

Applications:

DATEM finds use in various bakery products where dough strength and texture are important:

  • Breads: Improves dough handling, elasticity, and loaf volume, particularly in crusty breads like rye bread.
  • Cakes and pastries: Can contribute to a finer crumb and improved texture.
  • Cookies and crackers: May help achieve a desired crispness and prevent excessive spreading.

Safety:

  • Generally recognized as safe (GRAS) by the FDA for its intended uses in food when used within limitations.
  • However, some people might have sensitivities to tartaric acid or acetic acid.

Alternatives:

There are alternative dough strengtheners used in baking, such as:

  • Salt: Improves gluten strength and fermentation.
  • L-cysteine: A naturally occurring amino acid that strengthens dough.
  • Vital wheat gluten: Concentrated gluten protein for added strength and elasticity.

Important Considerations:

  • While generally safe, DATEM might not be suitable for everyone due to potential sensitivities.
  • The amount of DATEM allowed in food is regulated to ensure safety.
