Electrochemical nonenzymatic sensor for cholesterol determination in food
Original language description
The treatment of some inborn metabolism errors requires cholesterol substitution therapy. Cholesterol plays a vital role in the human body. Therefore, the majority of cholesterol determination techniques are targeted to blood and blood serum. Nevertheless, cholesterol determination in food is important as well. In this paper, cholesterol determination using differential pulse voltammetry (DPV) in dairy products (e.g., milk, clotted cream, yogurt, butter, etc.) is reported with a novel nonenzymatic sensor based on diphosphonic acid of 1,4-diacetylglycoluril (DPADGU) as an electrode surface modifier. Stable anodic response was obtained from cholesterol on the modified carbon-based electrode. The sensor has high stability, sensitivity (20 mu A mol L-1 cm(-2)), and a wide linear range from 1 up to 200 mu M. The LOD and LOQ values are 1.5 and 5.1 mu M, respectively. The developed methods were successfully applied to the above mentioned dairy products.
