• 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).
  • 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.
  • 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).
  • What if the oil temperature exceeds 65¡ãC?
  • When the oil temperature exceeds 65¡ãC, the machine runs smoothly without cooling devices and has a long service life. Only physical pressing is used, the cold pressing process will not produce high temperature, will not damage the organic components of the oil, the oil output is high in purity, and the product quality is good.
  • What is a good soil pH for Tung?
  • Soils in the Florida tung belt are slightly to strongly acid, typically ranging from pH 5.0 to 6.5. Tung requires a moderately acid soil, but it is often recommended to lime acid soils to pH 6.0. This will increase available phosphorus and potentially cation exchange from soil colloids.
