4. 3. Cholesterol oxidation products : analytical methods and levels in sweets containing heated butter oil

   University essay from SLU/Dept. of Food Science

   Author : Sarojini Jayantha Kumari Ubhayasekera; [2004]
   Keywords : butter oil; cholesterol; cholesterol oxidation products; COP; ghee; lipid oxidation; saponification; tallow; transesterification;

   Abstract : Various methods are used to analyse cholesterol oxidation products (COP) due to the unavailability of a standard method. In order to select a suitable method for the enrichment of COP, three methods of saponication (A – C),and transesterication (D) of tallow with three levels (5,10 and 20 µg) of spiked COP, were evaluated.
