Electron beam irradiation (EBI) pretreatment on lignocellulosic biomass (LCB) enables the usage of lignin or cellulose/hemicellulose for value-added products. Empty fruit bunch (EFB) and oil palm frond (OPF) were EBI-wet-soaked pretreated (under vacuum VC or non-vacuum NVC conditions), investigating for the change of crystallinity as indicated by the crystallinity index (CrI) values. Under VC and NVC conditions, the CrI was found to be decreasing and nearly all increasing at various EBI irradiation doses, respectively. The calculated CrI effectiveness percentage (CrI%) of the EBI-wet-soaked pretreatment, in preliminary indicating, relatively higher CrI% for the VC preparation, being preferred during EBI-wet-soaked pretreatment prior for the enzymatic hydrolysis for biofuel route. © 2023 Elsevier Ltd.
