To know more about the deodorization process, see the article written by Wim de Greyt, Desmet Ballestra 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 Deodoriser, the Multistock®.

For both systems, we can propose the Sublimax Ice Condensing System.
