Abstract:
      The effects of initial peroxide value, headspace residual oxygen content in packaged sunflower seed oil and temperature on oxidative stability of sunflower seed oil within the shelf life were mainly studied. The results showed that the combination of oxygen and high temperature could accelerate the oxidation of sunflower seed oil, and the effect of pure high temperature on sunflower seed oil was not significant under anaerobic condition. When the initial peroxide value of sunflower seed oil before filling was less than 2.5 mmol/kg, the peroxide value of the packaged sunflower seed oil could meet the national standard within the shelf life in the state of the maximum residual oxygen content. The lower the residual oxygen content in the headspace of the bottle, the more favorable for the quality of packaged sunflower seed oil.
