The influence of metallic ions (Fe (II), Fe (TII), Cu (II)) and the effect of antioxidants and chelating agents on the dissolved oxygen in O/W type emulsion was in vestigated by employing Beckman Oxygen Analyzer Model 777.
Vegetable oils with different P.O.V. and water were emulsified into O/W type emulsion using Tween-40, and the absorption of dissolved oxygen was investigated under the presence of Fe (II), Fe (III), and Cu (II) ions. Then citric and tartaric acids as chelating agents, and PG and BHA as antioxidants were added and their influence were investigated. The result showed that the oxygen absorption increases in the order of Fe (II) >> Fe (III) > Cu (II) and this effect was suppressed by the addition of PG and BHA. Chelating agents also showed their effects for low P.O.V. samples, but the effect was not observed for Fe (II) ion for high P.O.V. samples.
