Application of a DSC model for the evaluation of TPC in thermo-oxidized oils
Abstract
This paper deals with the measurement of total polar compounds in thermo-oxidized vegetable oils. A rapid method based on differential scanning calorimetry (DSC) is developed and validated against the reference method based on column chromatography. A not oil-specific correlation was established between total polar compounds (TPC) and crystallization parameters of vegetable oils taking into account their polyunsaturated fatty acid content (PUFA).
