Abstract
The seed and seed oil of Hura crepitans were analyzed for proximate composition and
physico-chemical characteristics. The seed is a good source of oil and protein; these were
found to be 37.78% and 22.20% respectively. The saponification and iodine values suggest
the use of this oil in liquid soap, shampoo and oil based ice cream production. The moisture
content is also low (3.00%) which indicates the possibility of long shelve-life. The
degradation kinetic of the oil was also investigated. The thermal oxidation of the double
bonds of the oil showed a first-order thermal oxidation kinetic and the Arrhenius plot
yielded a straight line with a slope equivalent to activation energy of 1.989KJ\mol.There is
the possibility of considering the seed as feed supplement and its oil for industrial
application.
