E640Fine

Glycine

Group: Flavour enhancers

Harm level1 of 5No concern

In plain words

Glycine is the simplest amino acid, which the body makes itself and which tastes slightly sweet. It is added as a flavour enhancer to some drinks, sauces and flavoured products.

Where you find it: sauces, drinks, supplements

Our recommendation

No need to avoid it.

Possible risks and effects

  • No relevant risk known at normal intake.

For experts

E640 covers glycine and its sodium salt; a non-essential amino acid that is a normal component of proteins, especially collagen. In food it acts as a flavour enhancer and buffer; intake from the additive is small compared with that from ordinary diet.
