Digest half of Chinese food stored in freezer regularly (6)
I believe the answer is:
resume
'digest' is the definition.
(thesaurus)
'half of chinese food stored in freezer regularly' is the wordplay.
'half of' suggests halving the letters.
'chinese food' becomes 'dim sum' (I've seen this before).
'stored in' indicates putting letters inside.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
The alternating letters of 'freezer' are 'ree'.
'dimsum' with half the letters taken is 'sum'.
'sum' placed into 'ree' is 'RESUME'.
(Other definitions for resume that I've seen before include "Short descriptive summary" , "Begin activity again" , "Abstract" , "Go on after a pause" , "proceed" .)
