| dc.description.abstract | The environmental influence on the oxidative rancidity of tropical soybean oil found in local markets in Ogun state Nigeria has been investigated in aqueous, alkaline, neutral, metal and acid environments and the results shows that the peroxide values measured as MeqO2/Kg were in the range of 3.48 – 11.82 for the acid environment, 3.24 – 10.94 in alkaline environment, 3.27 – 10.22 in metal environment, 3.16 – 9.86 in aqueous environment and 2.48 – 4.46 in neutral or normal environment. The peroxide value showed significantly high values for the acid environment and closely followed by the alkaline and metal environments. The aqueous environment also showed high values as compared to the neutral or normal environment. The % FFA showed similar profiles in the range of 1.46 8.87 for the acid environment, 1.42 – 8.66 in alkaline environment, 1.28 – 6.48 in metal environment, 1.24 – 6.22 in aqueous environment and 1.12 – 2.48 in neutral or normal environment with the acid and alkaline environments showing high values of over 8.7. There was an observed close relationship in the acid and alkaline environments as well as metal and aqueous environments as shown in the plot. The Saponification values measured as mg(KOH)/g of oil also showed similar trend in the range of 194 – 284 for the acid environment, 192 – 285 in alkaline environment, 188 – 278 in metal environment, 186 – 273 in aqueous environment and 182 – 248 in neutral or normal environment. The effect of increasing the temperature on the peroxide value of the oil was also marked. It was shown that as the temperature increased from 30 °C to 120 °C, the peroxide value increased from 3.16 Meq/Kg to 15.22 MeqO2/Kg. | |
