  • 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.
  • Who sells edible oil in Zambia?
  • They hold about 45% of the Zambian edible oil market. MMMZ has their own processing plant with an oilseed crusher (200,000MT/annum capacity) and an edible oil refinery (140,000MT/annum capacity). They sell refined oil to wholesalers and the hotel industry, big retailers and also offer oil through dispensers via smaller outlets.
  • 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.
  • 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.
  • 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.
