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.
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 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.
