Fractionation of oil palm fronds (OPF) by ozonolysis for enhanced sugar production

This study investigates the potential of ozonolysis pretreatment on oil palm frond (OPF) for enhancing total reducing sugar (TRS) recovery. The OPF is pretreated by ozonolysis prior to two-step acid hydrolysis. The effect of ozonolysis pretreatment on the physico-chemical properties of OPF is scruti...
