Comparing the results obtained in this work with those from the literature, three major differences can
be found. First, the moisture content in our samples is substantially higher (Lago et al., 2001). This may
be due to different coffee extraction procedures (pressures) that soak SCG differently with water or to
different storage conditions of the SCG. The second difference lies on the cellulose content (Mussatto
et al., 2011b). This may be due to different kinds of coffee used in the tests, since it is known that
arabica and robusta have different properties. Finally, the HHV determined in this work is lower than
the value referenced in the literature (Bizzo, 2003). This may be due to either the much higher water
content of our SCG as well as to the different nature of the coffee samples in both studies.
