Food trapped, starter refused (4)
I believe the answer is:
tuck
'food' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for tuck that I've seen before include "stuff" , "Food - fold edges in" , "Fold - grub" , "Friar friend of Robin Hood - to gather - food" , "legendary friar" .)
