Air-dried particles with an approximate size of 40/+60
mesh, were extracted in a Soxhlet apparatus to determine
the percentage content of extractives based on standard
process [19]. The extractive-free meals were used to determine
the percentage contents of cellulose [20], hemicellulose
[21] and lignin [19] according to the standard
methods. Un-extracted air-dried chips with the same mesh
size 40/+60 were also used to determine ash content
according to Tappi T 211 om-02 [22].
