Last bit of fruit tortured soul eats? (5)
I believe the answer is:
lotus
'last bit of fruit' is the definition.
'lotus' can be an answer for 'fruit' (I've seen this before). I am not sure about the 'last bit of' bit.
I can't explain the rest of the clue.
(Other definitions for lotus that I've seen before include "Plant that mythically induces languor" , "Mythical plant inducing languor" , "Mythical fruit inducing dreamy state" , "One of the lilies" , "Aquatic plant" .)
