Orange juice bits (4)
I believe the answer is:
pulp
'orange juice bits' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for pulp that I've seen before include "Soft plant tissue" , "Soft fruit flesh" , "Soft moist mass, may be crushed" , "Soft, soggy mass" , "Mush" .)
