The stabilization of vegetable oil with antioxidant combinations

In this paper, the effect of using hindered phenol, zinc dialkyl dithiocarbamate (ZDDC), tolutriazole derivative and combinations thereof to inhibit a blend of commodity Canola Oil and high oleic content soybean oil (1: 1) was investigated.Specifically, oils were oxidized by bubbling oxygen through 300 mL samples heated at 95 ℃. Antioxidant depletion rates were indirectly monitored by measuring oxidation induction times (OIT) as determined by Pressure Differential Scanning Calorimetry (PDSC). Preliminary data indicated that oil treated with only ZDDC had the slowest rate of antioxidant depletion.
