Oil Oxidation Prevention

Request Number N268198
Need details

Unilever wants to prevent oil oxidation in spreads and dressings emulsions, where the solution needs to be label-friendly.



Oil oxidation is a well-known problem in food emulsions. It has an adverse effect on the sensory perception of the product. The current challenge is to prevent oil oxidation through a label-friendly solution, i.e., the proposed ingredient/technology should meet the naturalness criteria without negatively impacting the flavour, appearance and overall quality of the product.

Various commercially available anti-oxidants have been tested, but so far with either limited anti-oxidant potency, or with taste problems.


Key Success Criteria

At the least, the proposed solution must meet the following criteria:

  • Work at pH < 4, and at high ionic strength
  • Proof of Principle already successfully tested
  • Works under chilled as well as under ambient conditions
  • Label-friendly / natural

Ideally, the solution will also meet these criteria:

  • Stop oxidation completely
  • Fit with standards of identity



Possible Approaches

Prevention or delay of oil oxidation through (combinations of):

  • Ingredients with anti-oxidant capacity
  • Specific processing techniques
  • Novel technologies
  • Packaging solutions


Approaches not of interest
  • Current commercially available natural anti-oxidants
  • Solutions with adverse sensory effects
  • Solutions with safety and/or regulatory issues
  • Solutions that contain GMO material
