Antioxidants Mode of Action

Consumers Select Based on Colour

It is widely accepted that consumers select a food product with their eyes, so products need to look fresh and tasty.

Oxidation is the Enemy

Oxidation, a chain reaction that occurs in the presence of oxygen, is responsible for the deterioration of food products, including off-flavours and off-odours. This process is affected by processing, packaging and storing techniques, as well as product ingredients.

Process of Lipid Oxidation

What are Antioxidants?

Antioxidants are molecules that:

  • Significantly delay or prevent oxidation
  • Help maintain fresh appearance and colour
  • Extend shelf life

How Do They Work?

Antioxidants delay the onset of oxidation by donating hydrogen atoms to quench free radicals, forming a stable antioxidant radical that is unable to participate in propagation reactions, slowing down oxidation.
