  • Does solvent extraction reduce -tocopherol in soybean oil?
  • Kania et al. (2004) reported that solvent extraction of soybean oil yielded higher total tocopherols content (1448 mg/kg) than cold pressing (1358 mg/kg), and the refining process led to the loss of ¦Á-tocopherol by 37%, ¦Â-tocopherol by 56%, ¦Ã-tocopherol by 17%, and ¦Ä-tocopherol by 34% in solvent-extracted soybean oil.
  • Can cold pressed soybean oil improve thermo-stability?
  • This study aims to improve the thermo-stability of refined soybean oil by blending it with some cold-pressed oils. For this, cold-pressed and soybean oils were firstly characterized (K 232, K 270, acidity, peroxide value, iodine value, induction time, phenolic contents, and antioxidant activity).
  • Is soybean oil better than cold pressed oil?
  • Indeed, it can be noted that despite the best physicochemical parameters of soybean oil, due to the refining process it has undergone, the phenolic content and antioxidant activity were significantly lower than those of cold-pressed oils.
  • How to improve the quality of refined soybean oil?
  • Thus, in order to improve the quality of refined soybean oil, each of the cold-pressed oils was mixed at a percentage of 30% with soybean oil (70%), and the different parameters of blends were analyzed before and after thermal treatment. Physicochemical parameters, total phenolic compounds, and RSA of analyzed studied oils.
