  • 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.
  • When was tung oil produced?
  • Commercial tung oil production in the southeastern United States began with the first commercial processing plant in 1927 and increased rapidly from 1,000 tons produced in 1939 to 132,000 tons in 1952, yielding 42 million pounds of oil in this year of peak production (Potter and Crane 1957).
  • Where are tung trees grown?
  • Tung trees ( Vernicia fordii Hemsl.) are native to China and were grown in the U.S. Gulf Coast region, mostly U.S. Department of Agriculture (USDA) cold hardiness zones 8 and 9, for tung oil production from 1937 to 1969 ( Robb and Travis, 2013 ). Tung oil production ranged from northern Florida to Texas during the tung oil industry boom.
  • Where does tung tree oil come from?
  • Historically, tung tree ( Aleurites fordii Hemsl.) oil production occurred within a 75- to 100-mile-wide belt through the Gulf Coastal Plain, from east Texas to Georgia and south into the Florida Gainesville area (Snow 2013).
  • How much oil does a tung tree produce per acre?
  • At peak production, tung orchards typically produce 2 to 2.1 tons of fruit per acre that contains 18.5% to 20% oil content by weight (Duke 1983). Tung tree seed is a potential alternative crop in northern and central Florida on sites having relatively well-drained, fertile soils and adequate moisture.
  • What are tung trees used for?
  • At the current time, the most prominent use of tung trees is for landscape purposes including the recent release of ¡®Anna Bella¡¯, a nutless tung tree, from the TCSHL germplasm collection ( Rinehart et al., 2013 ). Recent studies on the unique qualities of tung oil have revived interest in domestic tung oil production as a specialty crop.
