To assess whether differential scanning calorimetry can reliably detect and quantify pig and buffalo body fat adulteration in cow and buffalo ghee.
Analyzed the melting and crystallization curves of cow and buffalo ghee samples adulterated with pig body fat, buffalo body fat, or coconut oil using differential scanning calorimetry (DSC).
Evaluated detection thresholds down to 5% adulterant concentration and compared thermal behavior against pure ghee and ghee from cottonseed-fed buffaloes.
Adulteration with pig or buffalo body fat produced a distinct high-temperature peak in melting and crystallization curves, reliably detecting contamination down to 5%.
Quantitative measurement was achieved for buffalo body fat adulteration based on crystallization curve analysis.
The assay failed to detect vegetable fats such as coconut oil and yielded false-positive profiles for ghee derived from cottonseed-fed buffaloes.
