The branded vegetable oils were (U<sub>1 </sub>- U<sub>13</sub>), U<sub>14</sub>- U<sub>17 </sub>= unbranded vegetable oils; U<sub>18</sub>- U<sub>19 </sub>= branded palm oils; U<sub>20</sub>- U<sub>24 </sub>= unbranded palm oils. Percentage moisture content, colour, odour and rancidity were the physicochemical parameters analysed. The percentage moisture content was found to be within the ranges of 0.00 – 0. 33%. Higher moisture content was observed in samples U<sub>13</sub> and U<sub>24</sub>. The colours and odour are in line with the standard of SON except for sample U<sub>22 </sub>which had an objectionable odour. There were records of rancidity in four (4) vegetable oils U<sub>1, </sub>U<sub>5</sub>, U<sub>16 </sub>and U<sub>17</sub> and two (2) palm oils, U<sub>20 </sub>and U<sub>22</sub> analyzed. The FTIR analysis indicated that there is unsaturated C-H stretching vibration peak of carbon chain at 3006 and 3648 cm<sup>-1</sup> for the unheated samples. In comparison, peaks attributable to the presence of an aromatic group was not identified in samples U<sub>5 </sub>and U<sub>15</sub> but was identified in H<sub>5</sub> and H<sub>15</sub> respectively. There was an increase in the peaks of sample U<sub>5</sub> from 3008 and 2925 cm<sup>-1</sup> to 3853 and 3646 cm<sup>-1</sup> in sample H<sub>5</sub>.&nbsp;&nbsp; Heating of edible oils at smoke point changes the composition of the oil slightly by the formation of new additional compounds.</p&gt;}, number={5}, journal={FUDMA JOURNAL OF SCIENCES}, author={BabatundeO.
