Abstract:

Cholesterol content was determined with HPLC method for identification of hogwash oil-adulterated rapeseed oil. A good linear correlation between the adulteration amount of hogwash oil and the cholesterol content, and cholesterol was not detected in qualified rapeseed oil. Thus cholesterol content could be used as an indicator for identification of oil adulterated with hogwash oil with the lowest detection limit of 0.05 mg/g.

Key words: rape seed oil, hogwash oil, cholesterol, chromatography
