Abstract:
The synthetic antioxidants like Butylated Hydroxyanisole, Tertiary Butyl hydroquinone are permissible to the tune of maximum 200 ppm in fats and oils. In the present study the possibility of using Cerium (IV) oxide nanoparticles (CeO₂) to detect adulteration of these antioxidants in milk fats. 20% dispersion of CeO₂ 20 µL of CeO₂ as well as CeO₂ impregnated dried paper discs did not show a change in color after the addition of antioxidant BHA and TBHQ (0.02, 0.01, 0.005 and 0.0025%) solutions in acetonitrile. Discsensor wasfabricated by using whatman filter paper 4 and cut into small squares of approximately (0.5x0.5 cm) size by using a scissor. The CeO₂ 20% dispersion was directly absorbed into square disc and evaporated at 85 °C for 5 min. The standard antioxidants were applied 20 µL in different concentration for BHA and TBHQ (0.0025, 0.005, 0.01and 0.02%) and for other antioxidants (0, 1, 2, 3, 4, 5 and 10 mM) into disc. The color change was observed in Gallic Acid, Ascorbic Acid and Ascorbyl Palmitate by using the same concentration of CeO₂ dispersion and dried paper discs.
