- •
Sunflower biodiesel was stabilized with a hindered phenol antioxidant.
- •
Oxidative stability is defined by the length of the Rancimat induction period (IP).
- •
A novel Rancimat response function allows automated IP determination.
- •
IP follows an Arrhenius temperature dependence.
- •
IP increased linearly with antioxidant concentration.
