This is the first detailed study of the pyrolysis kinetics of FRSC. In this study, the performance of five methods for the determination of the kinetic parameters of fodder radish seed cake (FRSC) pyrolysis was evaluated. The application of an unsuitable method may lead to unreliable kinetic parameters. The scientific community has shown concern about the suitable application of different methods (model-free/model-fitting) for the determination of kinetic parameters. Based on trace elements determined in this study, the suitable quantity of sunflower oil consumption varies according to individuals aged 8, 18, and 30 years and will be deemed 0.61, 1.46, and 1.65 g/kg, respectively, attending HI = 0.99 and CR < 10 ⁻⁴. Sunflower oil quantities daily consumption were calculated by taking into account non-carcinogenic risk (CR < 10 ⁻⁴ ), and total non-carcinogenic hazard index (HI < 1). Concentrations of Zn, Fe, Al, Cu, and Mn were lower than FAO/WHO and DRI/AI limits, while Cr concentrations exceeded the FAO/WHO limits, which can be used as an indicator of the polluted ambiance. In addition, the concentrations of trace elements by ICP OES were ordered Zn > Fe > Al > Cu > Mn > Cr. The oil presented linoleic (54.00%) and oleic (37.29%) primary unsaturated fatty acids (91.67%), in which atherogenic (0.05), thrombogenic (0.16), hypocholesterolemic/hypercholesterolemic (21.97), peroxide (16.16), saponification (141.80), and relative density indices (0.92) demonstrated to be suitable for human consumption and possible health promotion. This study evaluated fatty acids composition, physicochemical, thermal, oxidative, and optical properties, and quantified trace elements in the sunflower oil extracted by a domestic cold-press machine. The consumption of regular vegetable oils has been linked to energy acquisition, nutritional benefits, health improvement, and the regulation of metabolic diseases. ![]()
