Lower chain fatty acids are unique to milk fat and they impart characteristic BR reading to ghee. Unsaturated fatty acids in ghee are less compared to vegetable oil which imparts a lower iodine value to ghee. There is a need to check reliability of various methods suggested for the detection of vegetable oils in ghee. The present study is to assess the suitability of different published analytical methods and to develop reliable test for detection of vegetable oils (cotton seed oil, groundnut oil, sunflower oil, corn oil, rice bran oil, palm oil, coconut oil, HVO and sesame oil) in ghee using DPPH reduction reaction. Studies on sensory characteristics of ghee revealed that sensory analysis alone cannot establish the adulteration of ghee by vegetable oils. The present study showed that estimation of BR (RI) reading and iodine value confirmed the ineffectiveness of these method in detecting adulteration of ghee with vegetable oils.EnglishThesis
