Propylene Glycol Esters of Fatty Acids
E477
E477, INS 477, propylene glycol esters of fatty acids, propane-1,2-diol esters of fatty acids, propylene glycol fatty acid esters
What it is
An emulsifying and texturising additive consisting of esters of propane-1,2-diol (propylene glycol) with fatty acids, identified in the EU as E477.
Why BOTIA flags it
BOTIA flags E477 because the same additive may be declared using 'propylene glycol' or the systematic 'propane-1,2-diol' wording.
BOTIA CAN
- Detect E477 and the principal propylene-glycol/propanediol ester names.
- Show the texture and E-number information layers.
BOTIA CANNOT
- Determine fatty-acid composition, concentration or manufacturing feedstock from the ingredient list.
- Confuse E477 with free propylene glycol or with propylene glycol alginate (E405).
