The objective was to study changes in water-saturated biodiesel irradiated by electron beam and to analyse them considering the influence of absorbed dose. Based on obtained results it can be concluded that irradiation did not affect ester groups in FAME molecules, but strongly influenced on double bonds. Total ester content decreased linearly with the increase in absorbed dose, causing FAME not to meet the requirement of PN-EN 14214 concerning the ester content (96.5 wt%). Therefore, the use of ionizing radiation to improve biodiesel properties is unlikely, but it is worth to consider electron beam sterilisation of this biofuel.
目的是研究电子束辐照下水饱和生物柴油的变化，并考虑吸收剂量的影响对其进行分析。根据所得结果可以得出结论，辐照不会影响脂肪酸甲酯（FAME）分子中的酯基，但会对双键产生强烈影响。总酯含量随吸收剂量的增加呈线性下降，导致FAME不符合PN-EN 14214关于酯含量（96.5 wt%）的要求。因此，利用电离辐射改善生物柴油性能的可能性不大，但值得考虑对这种生物燃料进行电子束灭菌。
