Ingredient in chocolate lures me, if I stray (10)

I believe the answer is:

emulsifier

'ingredient in chocolate' is the definition.

'lures me if i stray' is the wordplay.
'stray' is an anagram indicator.
'lures'+'me'+'if'+'i'='luresmeifi'
'luresmeifi' is an anagram of 'EMULSIFIER'.

(Another definition for emulsifier that I've seen is " Chemical agent".)

I've seen this clue in The Independent.
