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.
