Flavour enhancers are commonly added to commercially produced food products (eg. frozen dinners, instant soups, snackfoods) to make them taste more 'savoury'.
The commonly used flavour enhancers are:
Australian
- 621 monosodium glutamate, MSG
- 622 monopotassium glutamate
- 623 calcium diglutamate
- 624 monoammonium glutamate
- 625 magnesium diglutamate
European
- E620 Glutamic acid [Flavour enhancer] [possible reaction] [possibly GM]
- E621 Monosodium glutamate [Flavour enhancer] [possible reaction] [LGM]
- E622 Monopotassium glutamate [Flavour enhancer] [possible reaction] [possibly GM]
- E623 Calcium diglutamate [Flavour enhancer] [possible reaction] [possibly GM]
- E624 Monoammonium glutamate [Flavour enhancer] [possible reaction] [possibly GM]
- E625 Magnesium diglutamate [Flavour enhancer] [possible reaction] [possibly GM]
- E626 Guanylic acid [Flavour enhancer]
- E627 Disodium guanylate, sodium guanylate [Flavour enhancer]
- E628 Dipotassium guanylate [Flavour enhancer]
- E629 Calcium guanylate [Flavour enhancer]
- E630 Inosinic acid [Flavour enhancer]
- E631 Disodium inosinate [Flavour enhancer] [possibly of AO]
