Abstract
Fifteen commercial and 22 control samples of ghee were analysed for triglyceride compositions by
low-resolution short capillary column gas chromatography. Control samples of mixed milk and buffalo
milks exhibited maxima at C38 and C50. The detection level was found to be 2% in case of
beef tallow and coconut oil addition. Vegetable fat and lard addition could be detected at 5% and
6.3%, respectively. A sample survey based on triglyceride profile and standardised (S) values calculation
revealed up to 43% branded ghee samples and 87.5% samples of unbranded ghee did not
conform to triglyceride profiles of control ghee.
