At the end of the target extraction time (t),
the resulting dispersion was filtered through three layers of
cheesecloth and the extracted germ residue was used to determine
the remaining oil. The filtrate was centrifuged at 1700 g for 15 min
(Filarbo SV11, Meyzieu, France) and the supernatant was used for
determining oil bodies mean diameter (see Section 2.3).
