• What are the properties of Tung seed?
  • The applications of these properties are also discussed. The tung seed has an average of 13.24% (d.b.) moisture and 40.37% oil content. The average seed length, width, thickness were 22.61 mm, 20.35 mm, 13.95 mm, respectively.
  • What is the surface area of Tung seed?
  • The average surface area of tung seed is 1084.20 mm 2 while the sphericity and aspect ratio were 0.82 and 90.07%, respectively. The average bulk density of seed was 0.502 g/cm 3 while the true density was 0.995 g/cm 3, and the corresponding porosity was 49.88%. The terminal velocity was 8.3 m/s.
  • How much oil does tung oil produce?
  • By the year 1940s, the crop was covered nearly 100,000 ha in USA, producing about 300¨C400 kg ha ?1 of tung oil (Ma et al., 2007). The oil content of fruit is between 14 and 20%, the kernel 53¨C60% and the seed 30¨C40% (Okuda et al., 1975).
  • What is the tung oil content of fruit?
  • The oil content of fruit is between 14 and 20%, the kernel 53¨C60% and the seed 30¨C40% (Okuda et al., 1975). Tung oil is pale yellow or dark liquid and polymerization properties because of high content of ¦Á-elaeostearic acid.
  • Why is tung oil important?
  • The increasing commercial importance of the oil encouraged its introduction and cultivation in countries outside China. By the year 1940s, the crop was covered nearly 100,000 ha in USA, producing about 300¨C400 kg ha ?1 of tung oil (Ma et al., 2007).
  • What type of soil does Tung prefer?
  • Tung prefers slightly loamy light to medium soils. The ideal pH is around 5.5¨C6.0. Tung will tolerate more alkalinity, but it is likely to exhibit leaf roll and leaf scorch when the pH gets up past 7.0. A wide range of soils is acceptable, so long as it is well drained, penetrable and deeply aerated, but still has good moisture holding capacity.
