AB - A comparative study of sorption isotherms of sheanuts kernel
and Canarium pulp was conducted at 25, 35, 45 and 55°C. A semi-empirical
model was used to determine monolayer energy while an empirical method was used
to estimate hysteresis loop energies. Results indicate that Canarium has a thinner
hysteresis loop which decreases with increasing temperature. On the contrary,
sheanuts kernel hysteresis loop was constant through out the temperature range
studied. The estimated energies of the monolayer intermolecular attraction gave
a difference of 0.67-0.02 kJ mol•1 for Canarium which was lower
than that of sheanut kernel (1.09-0.29 kJ mol•1). The energy
of the hysteresis loop of sheanut kernel (103.60-63.89 kJ mol•1
from 25-55°C) was higher than that of Canarium pulp (10.18-2.94 kJ mol•1
from 25-55°C). It appears that dehydration of sheanuts kernel requires more
energy than Canarium pulp.
