Water was added to the dry groundnuts and the dried coconuts prior to pressing in order to raise the moisture content to 12 ± 1% (w.b.). Hammonds et al., 1991a and Hammonds et al., 1991b, Etherington et al. (1998) and Mpagalile and Clarke (2005) suggested that the moisture contents in the range of 10–13% had good oil extraction efficiency.
