'excessively worrying about e-numbers do cooking' is the definition.
I can't judge whether this definition defines the answer.

'about e-numbers do cooking' is the wordplay.
'about' becomes 'over' (both can mean around).
'cooking' indicates an anagram (cook can mean to falsify or distort).
'e'+'numbers'+'do'='enumbersdo'
'enumbersdo' anagrammed gives 'burdensome'.
'over'+'burdensome'='OVERBURDENSOME'
