  • Does refining temperature affect fatty acids in tea seed oil?
  • The traditional refining process for tea seed oil (Camellia oleifera oil) results in a severe loss of natural bioactive compounds and unsaturated fatty acids owing to the high operating temperatures. This study investigated the relationship between refining temperatures and the loss of various fatty acids and bioactive compounds in tea seed oil.
  • How to remove bioactive compounds from tea seed oil?
  • The losses of bioactive compounds in refined oil significantly reduced. The undesirable materials could be removed effectively by new refinery method. The traditional refining process for tea seed oil (Camellia oleifera oil) results in a severe loss of natural bioactive compounds and unsaturated fatty acids owing to the high operating temperatures.
  • What is the refining method for tea seed oil?
  • Currently, the traditional refining method for common vegetable oils is widely used for tea seed oil refining. This method comprises several steps: degumming, neutralization, bleaching, deodorization and dewaxing.
  • Can reducing operational temperatures improve the nutritional value of tea seed oil?
  • We have found that reducing the operational temperatures in most refining steps could effectively remove undesirable impurities and prevent the loss of bioactive compounds using the same processing times and vacuum pressures, thus preserving the nutritional value of tea seed oil.
  • Can tea seed oil be refined?
  • Crude tea seed oil is unpalatable owing to its bitter taste and the presence of phospholipids, so it must be refined to produce oil for human consumption. Currently, the traditional refining method for common vegetable oils is widely used for tea seed oil refining.
  • How to reduce BAP in tea seed oil?
  • The optimized refining processes can significantly decrease the level of BaP from 9.53 ± 0.02 µg kg ?1 in crude tea seed oil to 0.85 ± 0.10 µg kg ?1 in refined tea seed oil, and the other physicochemical indexes are in line with the international standard for refined oil.
