Abstract

Thermal and oxidative stability of sunflower and rapeseed oils were investigated by a complex thermoanalytical method using a derivatograph both in dynamic and static operating systems. A new heating unit facilitated a highly reproducible isothermal heating program. Thermal curves obtained under dynamic conditions were characteristic for the composition and pretreatment of the samples. Results gained under static conditions gave information on storability and oxidative changes occuring in the course of regular storage.
