  • 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.
  • Where do tea seeds come from?
  • Tea seeds (C. oleifera Abel var. Changeling) were collected from Kaihua Farm in Zhejiang Province, China, then cold-pressed with the oil being filtered through fine cheesecloth by the Health-Coming Camellia Oil Ltd. (Changshan, China).
  • 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.
  • 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 is the refractive index of tea seed oil determined?
  • The standard methods adopted for analyzing various chemical and physical properties were the Chinese National Standards for Tea Seed Oil (CNS-TSO), GB11765 and reports described elsewhere. Briefly, the refractive index was determined using a method similar to a previous report (Yunus and Rahman, 1988).
