Preserve in the film arm, a laden swallow (9)

I believe the answer is:

marmalade

'preserve' is the definition.
(I know that marmalade is a type of preserve)

'in the film arm a laden swallow' is the wordplay.
'in' says the answer is hidden in the clue.
'MARMALADE' is hidden in the letters of 'film arm a laden swallow'.

(Other definitions for marmalade that I've seen before include "Orange conserve" , "Sweet food" , "Orange preserve" , "Preserve made with citrus fruits" , "Spread" .)

I've seen this clue in the Sydney Morning Herald.
