FAQ
Frequently Asked Questions
Diglycerides (E471) are generally recognised as safe (GRAS) food additives. They are metabolised similarly to other fats. Concerns are less about diglycerides specifically and more about the overall quality and quantity of processed foods containing them.
The prefix refers to the number of fatty acid chains attached to a glycerol molecule: mono- (one), di- (two), and tri- (three). Triglycerides are the main form of fat in food and the body.
Yes, but in small amounts. They occur naturally as intermediates in the digestion of triglycerides in the gut and in the metabolic processes within cells. Most diglycerides in the food supply are manufactured.
Primarily as emulsifiers (E471) to help blend ingredients that normally separate, like oil and water, improving texture, consistency, and shelf-life in products like bread, cake, and ice cream.
A type of lipid (fat) molecule consisting of a glycerol backbone with two fatty acid chains attached.
Diglyceride is usually technical/scientific in register.
Diglyceride: in British English it is pronounced /daɪˈɡlɪs.ə.raɪd/, and in American English it is pronounced /daɪˈɡlɪs.ə.raɪd/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think: DI- (two) + GLYCER- (from glycerol, the backbone) + -IDE (like a chemical compound). It's a glycerol with TWO fatty 'rides' (acids) attached.
Conceptual Metaphor
A molecule is a connector (the glycerol backbone connecting two fatty acid chains).
