Abstract

One of the procedures for the stabilizing of frying oil, in order to preserve the synthetic antioxidants, is adding oils containing antioxidant and high Oxidative Stability compounds. The objective of this research was the quality evaluation of three frying oils mixture (Sunflower, Ladan and Iran) due to the addition of purslane and Corn Seed Oils and frying over 12 h at 170± 2  C for this reason, the mixed frying oil, containing corn and Purslane Seed Oil in the proportion of (70: 15: 15 w/w) called mixture 1, mixed frying oil containing corn and Purslane Seed Oil in the proportion of (75: 15: 10 w/w) called mixture 2, Corn Seed Oil, Purslane Seed Oil and mixture of three frying oils in terms of qualitative indexes (peroxide, p-anisidine, totox, total polar compounds, Oxidative Stability and conjugate-DNs), were evaluated. At first the antioxidant activity rate of Purslane Seed Oil was assessed and the value of 52. 9± 0. 19 percent was measured. The comparison of two types of frying oil mixtures indicated that the values of peroxide, p-anisidine, totox and conjugate-DNs, indicators of mixture 1 and 2 were (25. 83 meq/kg, 80. 63, 132. 29 and 15. 01 μ mol/g) and (28. 13 meq/kg, 85. 73, 141. 99 and 17. 17 μ mol/g) respectively which had significant difference with frying and other oils (P<0. 05). The higher ratio of purslane oil in the frying oil, mixture 1, increased its Oxidative Stability in contrast to oil mixture 2 and purslane preserved it against early degradation at high temperature.
