Detection of animal fat contaminations in sunflower oil by differential scanning calorimetry

In this study, the use of differential scanning calorimetric (DSC) heating thermograms was investigated to detect the presence of lard (LD), beef tallow (BT), and chicken fat (CF) as contaminants in sunflower oil. Sunflower oil samples spiked separately with LD, BT, and CF in levels ranging from 1 t...
