I'd returned with juice before fruit goes off (10)
I believe the answer is:
disappears
'goes off' is the definition.
(I've seen this before)
'i'd returned with juice before fruit' is the wordplay.
'returned' says the letters should be written backwards.
'with' means one lot of letters go next to another.
'juice' becomes 'sap' (I've seen this before).
'before' is a charade indicator (letters next to each other).
'fruit' becomes 'pears' (I've seen this before).
'id' written backwards gives 'di'.
'di'+'sap'+'pears'='DISAPPEARS'
(Other definitions for disappears that I've seen before include "becomes lost" , "goes missing" .)
