  • What is tung oil?
  • Tung oil or China wood oil is a drying oil obtained by pressing the seed from the nut of the tung tree ( Vernicia fordii ). Tung oil hardens upon exposure to air (through polymerization ), and the resulting coating is transparent and has a deep, almost wet look.
  • Are catechol-type lignan and neolignans found in tung tree seeds?
  • In this study, we show that the catechol-type lignan and neolignans are specifically present in the seed coat of the tung tree fruit seeds. The lignans were not detected in any other tissue, such as the pericarp, bark, leaves, or wood of the tree.
  • How much oil does a tung tree produce?
  • The tung tree produces large seeds with approximately 40¨C50% of their composition consisting of non-edible oil. ¦Á -Eleostearic acid makes up about 80% of tung oil, while linoleic acid and oleic acid make up 7 and 6%, respectively.
  • Can tung oil be oxidized?
  • The oil is readily oxidized due to the three conjugated double bonds in ¦Á -eleostearic acid. The drying oil has many applications in the lacquer industry and is used as a raw material for linoleum, resins, and artificial leather [ 4 ]. Tung oil is easy to dry by autoxidizing the oil components; however, it is stable inside the tung seed.
