NON-CONVENTIONAL OILSEEDS: UNLOCKING THE GLOBAL POTENTIAL FOR SUSTAINABLE BIOFUEL PRODUCTION

Renewable energy sources have become an urgent worldwide concern due to the impacts of global warming. Globally, biofuels can significantly reduce greenhouse gas emissions, which are major contributors to global warming. The use of biofuels has the poten-tial to transform the energy landscape while mitigating the adverse effects of traditional fossil fuels. This study examines the water features, biochemical compositions, and fatty acid profiles among various plant species. The results reveal significant variations in water features as a consequence of the relative water content and water potential of each seed. Also, we note that some non-edible species like A. blanchetii, C. procera, E. oleracea, P. juliflora, M. oleifera, and J. curcas have good attributes that confer a biofuel-like species. These attributes are high in oil content and have a good profile content of long-chain polyunsaturated fatty acids (LC-PUFAs), ranging from 35% to 80% among the different oilseeds. Fatty acid profiling reveals distinct compositions among the plant species. Stearic acid (C18:0), oleic acid (C18:1), and linoleic acid (C18:2) were the principal oils in A. blanchetii, J. curcas, P. juliflora, M. oleifera, and S. tuberosa compared to other species. M. oleifera stands out with a high linoleic acid (C18:1) content, while C. maxima, J. curcas, and P. juliflora are even higher (C18:2). A principal component analysis (PCA) and Pearson correlations analy-sis also confirmed that alternative oilseeds exhibited similarities to standard oilseeds and have the potential to replace them for biofuel production. These findings demonstrate the potential of non-conventional oilseeds for sustainable biofuel production. By unlocking their global potential, we can advance towards mitigating environmental impacts and fostering a sustainable biofuel industry.
