Deodorising
To know more about the deodorization process, see the article written by Wim de
Greyt, Desmet Oils & Fats R&D Manager, available at the AOCS
Lipid library.
Final stage in refining process
Deodorising is the final stage in oil refining. Deodorising removes odoriferous
material, free fatty acids and other undesired minor components to produce a
bland oil with a good shelf life.
State-of-the-art deodorising
Over the latest years, the aim of a state-of-the-art deodorising became:
Maximise:
-
odour, flavour removal
-
free fatty acid removal
-
colour reduction (heat bleaching)
-
peroxides destruction
Minimise:
-
losses in essential fatty acids (EPA/DHA)
-
creation of transisomerisation (TFA)
-
polymerisation
-
breakdown vitam. A+D+E
Organoleptic & Nutritional Value Shelf life
Final customers require a perfect oil with high organoleptic and nutritional
values, even one year after production.
Deodorising stages
The different stages in deodorising are :
-
Deaeration
-
Heating
-
Deodorising / steam stripping
-
Heat recovery / cooling
-
Final cooling
-
Polishing filtration
Top quality products require optimal conditions at all stages.
Available deodorising technologies
We supply a Continuous Deodoriser, the Qualistock® and a Feedstock change
