Impact of instant controlled pressure drop pre-treatment on solvent extraction of edible oil from rapeseed seeds
The fundamental analysis and modeling of kinetics of solvent extraction of rapeseed oil enable the quantification of the “washing” and “diffusion” steps. Both are illustrated through “starting accessibility” and “effective diffusivity”, respectively. This is a relevant...

| description | The fundamental analysis and modeling of kinetics of solvent extraction of rapeseed oil
enable the quantification of the “washing” and “diffusion” steps. Both are illustrated
through “starting accessibility” and “effective diffusivity”, respectively. This is a
relevant way to identify how to intensify and optimize the operating conditions in terms
of highest yield and lowest extraction time. Using the instant controlled pressure drop
(DIC) expansion as a pre-treatment for the intensification of the whole unit operation,
the starting accessibility ratio reached a value of 28.69% against 19.03% for the raw
material. Effective diffusivity of DIC treated samples reached a value of 2.05 × 10-12 m2/s instead of 0.72 × 10-12 m2/s for the raw material.
Regarding oil composition, predominant fatty acids in all extracted rapeseed oils are
oleic acid (C18:1 n9) ranged from 57.58 to 59.03%, linoleic acid (C18:2 n6) ranged from
21.23 to 21.89%, and linolenic acid (C18:3 n3) ranged from 9.11 to 9.45%. None of DIC
treatment produced a significant variation in relative fatty acid profile. |
